I bet you I can! Inner core, outer core, mantle, asthenosphere, lithosphere, crust
Hah! That's easy. The outer core is a liquid.
Can you tell me the formula for finding density?
Anything that is more dense than water will float, right?
Yeah! It's mass divided by volume.
No! Anything more dense than water will sink.
Oh really? Cool! How to you know?
The continents fit together like puzzle pieces and land forms and rock layers on different continents match. Also, alike species are separated by oceans and climate changes all prove that Pangaea was real.
Did you know that all of the continents used to be connected? It was called Pangaea.
Wait, what even is sea floor spreading?
Sea floor spreading is the process in which molten material from the mantle is pushed upward towards the surface and spread apart, creating new sea floor.
Today I found out that pillow lava, drill core samples, and magnetic striping is evidence of sea floor spreading.
Hey, do you know what the three types of boundaries are?
What are the results from each?
Convergent, divergent, and transform
Continental-continental convergent results in mountains. Continental-oceanic convergent results in volcanoes. Oceanic-oceanic results in island arcs. Divergent results in rifts and valleys. And transform boundaries have no result towards land forms.
Yea, sure. Convection currents are currents that occur in the asthenosphere...
Yeah. Gravity causes the convection cell to turn.
When convection currents rotate, they take the crust with them, causing some boundaries.
What are effects of convection currents?
Can you please tell me what convection currents are?
