the supercontinent that used to exist where all of earth's landmasses were connected together

A type of plate boundary where the two tectonic plates are moving away from each other

A type of plate boundary where the two tectonic plates are moving towards each other

A type of plate boundary where the two tectonic plates are sliding past each other

the theory that the Earth's crust/lithosphere is broken up into sections, called plates, that move around due to convection currents in the asthenosphere

currents that run through the asthenosphere due to the heat from the earth's core, these currents move the lithospheric plates

a process occurring at a divergent boundary under the ocean, where two tectonic plates move away from each other and magma comes rising up to form new ocean floor

a deep crack in the ocean floor, located at the subduction zones of the earth

any crack in the earth's lithosphere, such as the one in California between the Pacific plate and the North American plate

when sediments are moved from one place to another by wind, water, or ice

when sediments are laid down in a new location

a new piece of land created at the mouth of a river where sediments from the river are deposited into the ocean

A place where the earth's lithosphere is weak, and the earth's core is particularly hot, so the magma breaks through the lithosphere in that place and forms a volcano

A place around the Pacific plate where many volcanoes and earthquakes occur because this plate is so seismically active

pebbles and pieces of material left behind from a glacier moving

A type of plant that lived millions of years ago, and its fossils are found on 5 continents despite the large seeds it has that cannot cross oceans

The layer of the earth made up of crust AND upper mantle, this makes up the "tectonic plates" of the earth

The layer of the earth made up of middle mantle, where convection currents occur that move the plates

A large wave that results from an earthquake near the ocean
