How do scientists infer the internal structure of the Earth?

Back

Scientists analyze how earthquake waves move through Earth's interior to infer its structure.

What is the significance of planetesimals in Earth's formation?

Back

Violent collisions of planetesimals during the formation of the planet generated a significant amount of Earth's internal heat.

Front

What is the Earth's crust?

Back

The Earth's crust is the outermost layer of the Earth, composed of solid rock and minerals.

Front

What is the mantle?

Back

The mantle is the layer of the Earth between the crust and the outer core, composed of semi-solid rock that flows slowly.

Front

What is the outer core?

Back

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

Front

What is the inner core?

Back

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

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact with each other, causing geological events.
