Where do convection currents primarily occur within the Earth?

• In the Crust.

• In the Mantle.

• In the Outer Core.

• In the Inner Core.

What is the state of matter of the Outer Core?

• Solid

• Gas

• Liquid

• Plasma

What is the temperature range of the Inner Core?

• Approximately 2,000 to 3,000 degrees Celsius.

• Approximately 4,000 to 5,000 degrees Celsius.

• Approximately 6,000 to 7,000 degrees Celsius.

• Approximately 1,000 to 2,000 degrees Celsius.

What geological activity is associated with the movement of the Mantle?

• Earthquake activity and erosion.

• Plate tectonics and volcanic activity.

• Sedimentation and metamorphism.

• Weathering and glacial movement.

What is the correct order of the Earth's layers from the surface to the center?

• Crust, Outer Core, Mantle, Inner Core

• Crust, Mantle, Outer Core, Inner Core

• Mantle, Crust, Inner Core, Outer Core

• Outer Core, Inner Core, Crust, Mantle

What is the primary reason for the formation of convection currents in the Mantle?

• Heat from the Earth's core causes the mantle material to rise and fall.

• The rotation of the Earth creates a centrifugal force in the mantle.

• The presence of tectonic plates causes friction in the mantle.

• The cooling of the Earth's surface leads to sinking mantle material.
