Earth's Layers Flashcard

Front

What is the outer core of the Earth?

Back

The outer core is a liquid layer composed mainly of iron and nickel, located beneath the mantle and above the inner core.

What happens to temperature as you move towards the Earth's core?

Back

The temperature increases dramatically as you move closer to the core.

Front

How does the crust differ from the other layers of the Earth?

Back

The crust is thinner compared to the mantle and core, and it is the outermost layer of the Earth.

Front

What powers the convection currents in the Earth's mantle?

Back

The convection currents are powered by the heat from the Earth's core.

Front

What can be concluded about the density of the Earth's layers?

Back

The density of the Earth's layers increases as you move closer to the core.

Front

What are the main layers of the Earth?

Back

The main layers of the Earth are the crust, mantle, outer core, and inner core.

Front

What is the composition of the Earth's crust?

Back

The Earth's crust is primarily composed of solid rock, including minerals and various types of soil.

Front

What is the mantle made of?

Back

The mantle is made of semi-solid rock that flows slowly over time, composed mainly of silicate minerals.

Front

What is the inner core?

Back

The inner core is a solid sphere made primarily of iron and nickel, located at the center of the Earth.

Front

How does pressure change as you go deeper into the Earth?

Back

Pressure increases dramatically as you go deeper into the Earth.
