Eighth Grade - A1.3-4: Where Plates Meet.
This week we continue talking about plate tectonics, focusing on the boundaries where different plates meet.
Answer this: What are the different types of boundaries? What happens at each of these boundaries?
Contract 2 to be presented on Friday.
Seventh Grade - C1.3-4: Protista.
This week we examine more complex single-celled organisms.
Answer this: Where can protists be found? How are they more complex than bacteria?
Contract 2 to be presented on Friday.
Why do the plates move?
ReplyDeleteHe thoes a contracts are very good ones.
ReplyDeletebooyah! What makes the oceanic plates more dense than continental plates?
ReplyDeletetaylor, it's the convection currents in the mantle
ReplyDeleteWhy is the buttom of the ocean so cold if it is so far down?
ReplyDeletehow are mountians made
ReplyDeletei think the class is really fun but i wish the kids would talk more.
ReplyDeletehow are volcanos made?why?
ReplyDeleteWhy do hot stops stay in one spot?
ReplyDeleteumm what does dense mean??? i forgot hahah
ReplyDeleteWhat caudes the convection currents?
ReplyDeleteWould it be possible to go into the mantle useing a deep ocean trench?
ReplyDeletehow do they know that the core is so hot?
ReplyDeleteDense means the amout of mass in a given space.
ReplyDeleteWhy does the earth have tectonic plates?
ReplyDeleteWhy does the earth have tectonic plates?
ReplyDeleteWhy is the inner core solid?
ReplyDeletecody, mountains are made when tectonic plates hit each other
ReplyDeletewhy is the mantle so big
ReplyDeletewats mass then????
ReplyDeleteHow are deep ocean trenches made
ReplyDeleteWhy does the earth have weather
ReplyDeletePreston, the inner core is solid because of pressure
ReplyDeletehow is earth made
ReplyDeletewhat do u think what will happen with the land in 100,000,000 years? i think that all the land willbe gone because of erosion
ReplyDeleteI don't Know how to spell erosion.
ReplyDeletedeep ocean trenches are made by subduction
ReplyDeletemass is the space that matter takes up really, krissy
ReplyDeleteHey Mr. Hoopman Why is the Mantle hot?Tricky question Eh?
ReplyDeleteMatt, really tricky. It has to do with pressure and heat.
ReplyDeleteWhy is the San Andreas fault line not divided California yet?
ReplyDeleteWhere does the old oceanic crust go.
ReplyDeleteTate, the mantle is thicker because there is less pressure on it then the layers below. The crust is not6 thick because its a solid.
ReplyDeletemr.hoopman if the core is so hot and it only has to do with the pressure and heat how can the scientists tell how hot it is?
ReplyDeleteWhat happens with old ocean crust?
ReplyDeleteTaylor, the plates move because they're floating on the astenosphere; a hot layer of magma!
ReplyDeleteWhat are the plates underneath yellowstone???
ReplyDeleteMountains are made when a continental-continetal collision happens.
ReplyDeleteNatalie,mass is howmuch space somthing takes up.
ReplyDeletewouldn't the old ocean crust fill up the trenches
ReplyDeletedelany what do you mean by how mountains are made i dont get that!?
ReplyDeleteThat's volume, Randy
ReplyDeleteRift valleys are awesome.
ReplyDelete~Daniel
why is the in side of the earth so hot
ReplyDeleteWhat are the most common boundaries???
ReplyDeleteYellostone is like 1-8 of our core it is really cool!!
ReplyDeleteSteph, it happens when two plates carrying continental crust with the same density crash into each other.
ReplyDeletewhat is your prediction on what the earth will look like in the next 100million years
ReplyDeleteWhat happened during the San Franciso Earthquake
ReplyDeleteDid the earth ever not have plates???
ReplyDeleteThis comment has been removed by the author.
ReplyDeletemr hoopman why dont you answer our questions? you only comment on randy jkjk
ReplyDeleteWhat do scientists use to record and graph movments of earths tectonic plates
ReplyDeleteY is the Earth round???
ReplyDeletehow do trenches form
ReplyDeletevivien the earth always had plates because otherwise the pangaea thing wouldnt be able to happen
ReplyDeleteRandy, Heat rises.
ReplyDeleteSteph, because.
Kedie, gravity.
Why in the old days did people think the eath was the center of the univers and that eath was sqaure.
ReplyDeleteJack, different.
ReplyDeletewhy are the north and south pole the coldest when heat sinks and cold rises
ReplyDeletejacob ocean plates are more dense because they have the wieght of the water on them and the gravity of earth so that would make ocean plates more dense than continental plates
ReplyDeletei like the constracts we havedone
ReplyDeletewhy does the inner core get so hot?
ReplyDeletethe plates move because of the convection cells in the asthenosphere
ReplyDeletehow are the plates made???
ReplyDeletehow are mountains made
ReplyDeleteWhy do plates move?
ReplyDeleteHow are volcanoes made?
ReplyDeletewhy do the plates move?
ReplyDeleteHow far do plates move in a year?
ReplyDeleteWhat are convection cells?
ReplyDeletewhat are rift valleys
ReplyDeleteHow do we know what is in the middle of the earth...
ReplyDeletehow do the plate move
ReplyDeletemr. hoopman, why is there a trend in earhtquakes. For instance, why does the San Andreas fault line tend to have earthquakes every 150 years?
ReplyDeletewill we ever collasps in to the center of the earth someday
ReplyDeleteHow can we be sure that all of the layers of the Earth exist?
ReplyDeletehow do underwater earthquakes happen?
ReplyDeletewhat is a convection current
ReplyDeleteWhy would earthquakes happen more in one spot on a fault like on the San andreas fault earthquakes happen every 20-24 years near the town of Parkfield?
ReplyDeletelike mike said do people go into trenches
ReplyDeleteWhat is the difference of convection currents and convection cells?????????????
ReplyDeletehey mitch what is continental-continental collison
ReplyDeleteHoopman
ReplyDeleteIs this the kind of comment you would reject
Cooper,
ReplyDeleteYes.
do you think it will ever be possible to reach the center of the Earth?
ReplyDeletePlates move at 2-7 centimeters per year, depending on the plate. (very cool)
ReplyDeleteis magma just melted rock? or is it some other substance???
ReplyDeletei dont think so jessica it is to hot near the center of the earth
ReplyDeletethe earth is way to deep to dig to the center and to hot
ReplyDeletethe Earths magnetic field is from the Inner Core.
ReplyDeletebrady, pressure tends to build up in one area more than others, like on the bend near Parkfield.
ReplyDeleteProtists are fun.
ReplyDeletewhat are some kinds of bacteria
ReplyDeleteWhere can I find a good,bad virius
ReplyDeleteWhat is a protist?
ReplyDeletewhat does protist live on or in???????????
ReplyDeleteWhat are the biggest type of protist?
ReplyDeletewhy are all bacteria different shapes?
ReplyDeletewhat is encephalitis??
ReplyDeletewhat is a protist???
ReplyDeleteAre protist like little animals?
ReplyDeletewhat are protist?
ReplyDeleteis bacteria alive
ReplyDeletehow often do people get encephalitis...is it rare?
ReplyDeleteWhat is a virus?
ReplyDeletehow small are protist?
ReplyDeletehi mr.hoopman why do you think protist are cool?
ReplyDeleteare bacteria alive
ReplyDeleteHow Large and small can bacteria get to be????
ReplyDeletedo they have brains?
ReplyDeleteHow large can bacteria get?
ReplyDeleteis bactirea alive
ReplyDeleteAbout how many differents kinds of viruses are there?
ReplyDeletewhat is the werst virus??????????????????????
ReplyDeletewat r some kind of viruses
ReplyDeleteAbout how many different kinds of bacteria are there?
ReplyDeletewhat is the biggest kind of bacteria
ReplyDeleteJessica, no beacuse the futher do u go the hotter it gets so u'd burn up before u got there
ReplyDeletedo protists eat bacteria?
ReplyDeletehave u ever got sick from a virus???
ReplyDeletedo they hav organs
ReplyDeletehow long do viruses live? do they ever die?
ReplyDeletehow is a virus formed?
ReplyDeletewhat is the smallests bacteria
ReplyDeleteMr.hoopman do u think the world will ever find a way for us to survive and dwell under water
ReplyDeletemr hoopman what is ur belief on the world blowing up in 2012
ReplyDeletewest nile virus
ReplyDeleteWhy nis a viruse called a virus?
ReplyDeleteWhatis a protist and what does it do?
ReplyDeletewhy do measles cause you to get a red bumpy rash?
ReplyDeletebout how many types of bacteria are there in the world?
ReplyDeleteA protist s anorganism that has only one cell. They can be harmful and helpful
ReplyDeletehow many kinds of protists are in the world?
ReplyDeletewhat are the main protists
ReplyDeletebecause of gravity
ReplyDeletehow many proticts are there?
ReplyDeletewhat are small pox
ReplyDeletewhat exactly is tonsillitis is it a virus bacteria or what
ReplyDeleteshauna tonstillisious or wat ever you said is...a bacteria..well thats wat i think
ReplyDeleteRyan i am pretty sure that there are several groups
ReplyDeleteit is a baterial infection
ReplyDeleteHow fast do virisis kill sells?????
ReplyDeleteCan virisis get sick???????????????
ReplyDeleteHow do you know whats in the middle of the earth
ReplyDeleteJacob maybe in like 1or2 minutes
ReplyDeleteVirusus can't get sick because there not alive
ReplyDeleteJacob viruses kill cells as soon as the virus is done injecting and the new viruses break out or destroy the cell
ReplyDeletenate you should reaserch 1 of the groups
ReplyDeletemichael they dig a hole all the way down and look whats in the middle
ReplyDeleteHow long dose it take fore virisis to infect your body
ReplyDeleteTechnically, Viruses Can Get Sick From Bacteria That Attack It, And It Kills It After.
ReplyDeletelithosphere is mooooving
ReplyDeleteAre there some viruses good for you? or are all bad for you?
ReplyDeleteHow do viruses get inside and attack the human body?
ReplyDeleteA protist is a single cell organism that can be like a plant(photosynthesis),animal(eats organisms), or decomposer(breaks down dead plants & animals)
ReplyDeleteA protist is a single celled organism that can be like a plant(photosynthesis), an animal(eats other organisms), or a decomposer(breaks down dead organisms.) They live in places with water.
ReplyDeleteThe "scientists" say that in like 10-100 million years the continents will be conected again due to plate movement but what hapens after that?
ReplyDeletecompressional waves move back and forth, creating a ripple. they move through solids, liquids, and gases. (also called primary waves)
ReplyDeletetate, the mantle is so big because there is a larger quantity of the materials that make up the mantle than the materials that make up any other layer. get it?
ReplyDeleteWhy do we need good bacteria in our body
ReplyDeleteGood question, Jake. I would ask those scientists if the course plates are on today is the same course they will be on in 100 million years.
ReplyDeletealex, I would like to say "beacuse they are good" but I will say it is because we need them to do what they do. Your body is full of microscopic organisms that help you digest, get rid of wastes, etc.
In the ocean don't some waves that crash into each other either die out or grow larger? Then if it works in the ocean when the energy combines is it the same way with p+s earthquake waves or does it not work with land?
ReplyDeleteTaylor
ReplyDeletePlates move because underneath they're convection currents that repeat and move over and over just like water underneath a leaf (example of the water as the magma and a leaf as the plates)
how do most cells survive
ReplyDelete
