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
