I WONDER - What Is In The Earth’s Core?

The video explains the Earth's structure, consisting of the crust, mantle, and core. The crust is the outermost layer, with oceanic and continental types. The mantle, beneath the crust, is the largest layer and forms tectonic plates with the crust. These plates' movements can cause earthquakes. The core is divided into the outer core, which generates Earth's magnetic field, and the inner core, the hottest part of Earth, composed of solid nickel and iron.

What is the Earth's crust primarily composed of?

• Rocks, minerals, and soils

• Water and air

• Lava and magma

• Iron and nickel

Which type of crust is thinner?

• Continental crust

• Oceanic crust

• Both are the same thickness

• Neither, they are not part of the Earth's crust

What percentage of the Earth's volume does the mantle make up?

• 95%

• 85%

• 70%

• 50%

What is the primary role of the Earth's outer core?

• To provide nutrients to the crust

• To support tectonic plates

• To create a magnetic field

• To store water

What is the inner core primarily made of?

• Water and air

• Solid nickel and iron

• Lava and magma

• Rocks and minerals
