Plate Tectonics

Front

What type of boundary occurs when two plates slide past each other?

Back

Transform boundary: A type of plate boundary where two tectonic plates slide past one another, causing earthquakes.

Front

A rift valley occurs at a ____________ boundary.

Back

Divergent boundary: A type of plate boundary where two plates move away from each other, creating rift valleys.

Front

What is the outermost layer of the Earth called?

Back

Crust: The outer layer of hard, solid rock that is underneath the soil, vegetation, and water.

Front

What is convection in the context of plate tectonics?

Back

Convection: The process in which hot molten rock rises, cools, and then sinks back towards the core, driving plate movements.

Front

What is a convergent boundary?

Back

Convergent boundary: A type of plate boundary where two plates move towards each other, often causing one plate to be forced beneath another.

Front

What is a divergent boundary?

Back

Divergent boundary: A type of plate boundary where two tectonic plates move apart, leading to the formation of new crust.

Front

What geological feature is formed at a transform boundary?

Back

Fault lines: Transform boundaries can create fault lines, which are fractures in the Earth's crust where earthquakes can occur.

Front

What is the mantle?

Back

Mantle: The layer of the Earth located between the crust and the core, composed of semi-solid rock that flows slowly.

Front

What is the inner core?

Back

Inner core: The solid, innermost layer of the Earth, composed mainly of iron and nickel, and extremely hot.

Front

What is the outer core?

Back

Outer core: The liquid layer of the Earth located beneath the mantle and surrounding the inner core, responsible for Earth's magnetic field.
