Earth Science Flashcard

Front

What happens at a convergent plate boundary?

Back

At a convergent plate boundary, the denser crustal plate is pushed below the less dense plate, leading to subduction and destruction of the plate.

Front

What are stony meteorites?

Back

Stony meteorites are types of meteorites made up of minerals that contain silicates.

Front

What does the continental drift theory state?

Back

The continental drift theory states that continental landmasses were moving or drifting across the Earth.

Front

What is the lithosphere?

Back

The lithosphere is the outermost layer of the Earth, made up of the crust and the upper mantle, which is broken into large, irregularly shaped slabs of rock.

Front

What is the role of the inner core in Earth science?

Back

The inner core is responsible for generating the Earth's magnetic field.

Front

What occurs at mid-oceanic ridges?

Back

At mid-oceanic ridges, the seafloor separates, allowing new crust to form from rising magma.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate is pushed below another into the mantle.

Front

What are the three main types of meteorites?

Back

The three main types of meteorites are stony meteorites, stony-iron meteorites, and iron meteorites.

Front

What is plate tectonics?

Back

Plate tectonics is the theory that explains the movement of the Earth's lithosphere, which is divided into tectonic plates.

Front

What is the outer core?

Back

The outer core is a liquid layer of the Earth located beneath the mantle and above the inner core, contributing to the Earth's magnetic field.
