What are the layers of the Earth?

Back

The Earth has four main layers: the crust, mantle, outer core, and inner core.

Front

What is the crust?

Back

The crust is the outermost layer of the Earth, which is solid and relatively thin compared to the other layers.

Front

What is the mantle?

Back

The mantle is the layer beneath the crust, made of semi-solid rock that flows slowly over time.

Front

What is the outer core?

Back

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

Front

What is the inner core?

Back

The inner core is the solid innermost layer of the Earth, made primarily of iron and nickel.

Front

What causes mountains to form?

Back

Mountains typically form at the borders of tectonic plates due to the collision and movement of these plates.

Front

What is the Ring of Fire?

Back

The Ring of Fire is a region in the Pacific Ocean known for its high volcanic and seismic activity, formed by tectonic plate movements.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's crust that move and interact with each other.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces due to environmental factors.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another by wind, water, or ice.
