The Earth shape is

• sphere

• Circle

• Perfect sphere

The Earth is made up of…………..

• The Earth consists solely of rocks and minerals.
• The Earth is made up of layers including the crust, mantle, outer core, and inner core.
• The Earth is a solid mass with no internal structure.
• The Earth is made up of water and air only.

How many layers does the Earth have?

• 5
• 3
• 6
• 4

What is the name of the earths layer that we live on?

• crust
• atmosphere
• core
• mantle

What is the thinnest layer of earth?

• The crust
• The mantle
• The outer core
• The inner core

The Earth crust is made of

• Sand and clay
• Plastic and metal
• Rocks and minerals

• Water and air

The Earth crust is divided into

• tectonic plates
• continental crust (land)

• magnetic fields
• oceanic crust (sea)

Why is the oceanic crust and continental crust different?

• The oceanic crust is thicker and less dense than the continental crust.
• Both oceanic and continental crust have the same density and thickness.
• The oceanic crust is primarily made of granite, while the continental crust is made of basalt.
• Because the main types of rock on these layers is different

The mantle is divided into

• inner mantle and outer mantle
• solid mantle and liquid mantle
• continental mantle and oceanic mantle
• upper mantle and lower mantle

Which layer is immediately below the crust?

• core
• atmosphere
• lithosphere
• Upper mantle
