8th Grade Science CH 4 Review

the process by which molten material adds new oceanic crust to the ocean floor

Since this is happening on land, what is it called?

Which type of convergent boundary is this?

where tectonic plates move apart from each other

deep underwater canyons

Which type of convergent boundary is this?

What is happening here?

uneven pieces of Earth’s lithosphere

What type of boundary is this?

mountain ranges that run along the middle of some ocean floors

any trace of an ancient organism that has been preserved in rock

What do you see happening here?

process by which the ocean floor sinks beneath a deep-ocean trench and back into the mantle

Earth’s lithosphere is in constant motion, driven by convection currents in the mantle

The idea that continents slowly moved over Earth’s surface

What type of boundary is this?

the last supercontinent where all the continents were joined together

breaks in Earth’s crust where rocks have slipped past each other

where tectonic plates come together

What type of boundary is this?

where tectonic plates slip past each other

deep valley where pieces of Earth’s crust diverge on land
