Earth's Structure and Movement

The San Andreas Fault in CA is an example of this type of plate boundary

• Divergent - dividing

• Convergent - colliding

• Transform - sliding

The Great Rift Valley in Africa and the Mid-Atlantic Ridge in the Atlantic Ocean are both results of this type of plate boundary - where new land is being created!

• Divergent - dividing

• Transform - sliding

• Convergent - colliding

Mountains are formed at this type of plate boundary, specifically the Himalayas and Appalachians

• Transform - sliding

• Divergent - dividing

• Convergent - colliding

When an oceanic plate and a continental plate meet, which will subduct under the other?

• oceanic under continental

• continental under oceanic

• depends on how hot and heavy they are

Tectonic plates can melt and create new land

• never, that's crazy!

• if they are sucked inside a volcano and turn to goo because the lava is so hot

• if they are pushed under other plates into the mantle where heat and pressure turn the plate back into magma and then it is spewed out of a volcano and hardens into new crust

• When the crust splits open and the magma cools off

Mountains are formed when

• One plate subducts under another one

• When plates slide past one another and get stuck

• When two plates push towards one another and the land bulges up

• When there is a weak spot in the Earth's crust, and magma shoots out as lava

• Crust

• Outer Core

• Mantle

The portion of the Earth that supports the crust
