Plate Tectonics

Most geologists think that the movement of Earth's tectonic plates is caused by

• the rotation of the Earth.

• the Earth's magnetic field.

• subduction.

• convection currents.

The theory that giant pieces of the Earth move over time is called

• plate tectonics

• tectonic plates

• seismology

• cryptozoology

It is most common for a ________________ to form at divergent plate boundaries.

• mid-ocean ridge and new ocean basin

• giant hole

• earthquake

• tornado

Mountains on land are/were usually formed at __________ plate boundaries.

• transform

• divergent

• convergent

When plates collide we get ________.

• crumbles

• volcanos

• trenches

• mountain ranges

A valley in the ocean created when one lithosphere plate subducts under another

• Canyon

• Ridge

• Mountain

• Deep-ocean Trench

The divergent plate boundary found in the Atlantic Ocean is creating

• an underwater mountain chain

• islands

• massive earthquakes

• hurricanes

A tectonic plate is a giant piece of the Earth's

• lithosphere that moves

• lithosphere that stays in place

• lower mantle

• outer core

The place where two plates come together is known as a _______

• transform boundary.

• divergent boundary.

• convergent boundary.

• rift valley.

• the process of one tectonic plate sliding beneath another

• convergent boundaries

• tectonic plates that make up the continents

• oceanic plates

• tectonic plates that make up the ocean floor
