Geosphere Study Quiz

What is the Lithosphere?

• The layer of the Earth's atmosphere that contains the ionosphere
• The layer of the Earth's atmosphere that contains the clouds
• Composed of the crust and the uppermost mantle with a thickness of about 100 kilometers, it is the portion of the surface that moves around during tectonic activity.

• The layer of the Earth's atmosphere that contains the ozone layer

What is the inner core of the earth made of?

• Liquid gold and silver
• Gaseous oxygen and nitrogen
• Solid copper and aluminum
• Solid iron and nickel

What is the outer core of the earth?

• A layer of solid gold and silver
• A layer of frozen water and carbon dioxide
• A layer of fluffy clouds and rainbows
• A layer of molten iron and nickel

What is the mantle?

• A type of clothing worn over the shoulders
• The layer of the Earth between the crust and the core
• The outermost layer of the Earth
• A type of decorative covering for a fireplace

What is the crust of the earth made of?

• Low density silicates

• Molten lava and magma
• Ice and snow
• Metal and steel

It is more plastic or ductile than the lithosphere. The lithosphere rides on top of the bendable ------ during tectonic activity.

• asthenosphere
• mantle
• crust
• core

_________ , the driving force of plate tectonics, this is when hotter magma rises toward the surface and cooler, denser magma falls deeper into the mantle, pulling the plates along.

• Evaporation
• Convection Current

• Condensation
• Sublimation

What is the driving force of plate tectonics?

• Convection Current

• Transpiration

• Thermal Pollution

• Eutrophication

________: A break in the lithosphere where magma comes up and pushes the plates away from each other.

• Canyon
• Volcano
• Trench
• Divergent Plate Boundary

___________: When a convergent plate boundary results in the denser plate sliding down and underneath the less dense plate. This happens when at least one of the plates is an ocean plate, which is denser and thinner than continental plates.

• Mantle plume
• Subduction
• Crustal uplift
• Erosion
