6.E.2.1 Layers of the Earth (snet)

Front

What is the inner core of the Earth?

Back

The inner core is the solid innermost layer of the Earth, composed mainly of iron and nickel, and is under extreme pressure.

Front

What are the main components of Earth's core?

Back

The Earth's core consists of a solid inner core surrounded by a liquid outer core.

Front

Why is the inner core solid despite high temperatures?

Back

The inner core is solid due to the immense pressure that prevents the iron and nickel from melting.

Front

What is the difference between oceanic crust and continental crust?

Back

Oceanic crust is more dense than continental crust and is primarily composed of basalt, while continental crust is primarily composed of granite.

Front

What is the composition of the Earth's crust?

Back

The Earth's crust is composed of a variety of rocks, including igneous, sedimentary, and metamorphic rocks.

Front

What is the outer core of the Earth?

Back

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

Front

What role does pressure play in the state of the Earth's inner core?

Back

The extreme pressure at the Earth's center keeps the inner core solid despite its high temperature.

Front

What is the primary element found in the Earth's crust?

Back

Oxygen is the most abundant element in the Earth's crust, followed by silicon.

Front

How does the density of oceanic crust compare to continental crust?

Back

Oceanic crust is denser than continental crust, which is why it sits lower in the mantle.

Front

What is the temperature range of the Earth's inner core?

Back

The temperature of the Earth's inner core is estimated to be between 4,000 to 5,000 degrees Celsius.
