Tectonic Plates, Plate Boundaries

hardness

A property of minerals determined by scratching a mineral with objects of known hardness levels

divergent boundary

This boundary causes plates to move apart. Magma rises between them, creating new ocean basins.

transform boundary

This type of boundary has plates that slide past each other, build friction, and release energy as an earthquake.

convection

This type of heat transfer in the mantle causes the lithospheric plates to move.

mountains

What landform results when 2 continental plates collide?

continental drift

What theory did Alfred Wegener propose?

subduction

When an oceanic plate collides with a continental plate, the oceanic plate is pushed back into Earth's mantle by the process of ____________________________.

volcanoes

When an oceanic plate collides with a continental plate, the oceanic plate is subducted, melts, and rises back to the surface causing _____________________________ to form.

asthenosphere

Which layer of Earth contains the middle mantle, and is a solid that flows like a liquid?

lithosphere

Which layer of the Earth contains the crust and upper mantle mantle, and is broken into plates?

North American Plate

Which plate do we live on?

Eurasian Plate

Which plate includes Europe and Asia?

Antarctic Plate

Which plate includes the South Pole?

Pacific Plate

Which plate includes the coast of California and extends all the way to Japan?

radiation

Which type of heat transfer causes the sand in a desert to get hot during the day?

sedimentary rock

a rock that forms from compressed or cemented layers of sediment

metamorphic rock

a rock that forms from millions of years of heat and pressure

igneous rock

rock that forms when magma cools and solidifies
