Earth's Layers

What is the lithosphere?

• The lithosphere is the rigid outer layer of the Earth, consisting of the crust and the uppermost part of the mantle.

• The lithosphere is a layer of liquid rock beneath the Earth's surface.

• The lithosphere is the gaseous envelope surrounding the Earth.

• The lithosphere is the inner core of the Earth made of solid iron.

What is the Earth's crust?

• The Earth's crust is the outermost layer of the Earth, located above the mantle and below the atmosphere.

• The Earth's crust is a liquid layer that surrounds the core of the Earth.

• The Earth's crust is the thickest layer of the Earth, composed mainly of gases.

• The Earth's crust is a layer of molten rock that is constantly moving.

What is the state of matter of the outer core?

• Solid

• Gas

• Liquid

• Plasma

What is the inner core?

• The outermost layer of the Earth, composed of soil and rock.

• The solid innermost layer of the Earth, composed mainly of iron and nickel, and is extremely hot.

• A liquid layer surrounding the outer core, made of molten rock.

• The layer of the Earth that contains the atmosphere and weather patterns.

What is plasticity in the context of Earth's layers?

• Plasticity refers to the ability of a material to flow and deform under pressure, as seen in the asthenosphere.

• Plasticity is the process by which rocks become igneous through cooling.

• Plasticity describes the rigidity of the Earth's crust under extreme temperatures.

• Plasticity refers to the ability of a material to remain unchanged under stress.

What happens to temperature as you go deeper into the Earth?

• Temperature decreases as you go deeper into the Earth.

• Temperature remains constant regardless of depth.

• Temperature generally increases as you go deeper into the Earth, reaching extremely high temperatures in the inner core.

• Temperature fluctuates randomly with depth.

How does density change as you move from the Earth's crust to the outer core?

• Density remains constant throughout the layers.

• Density decreases from the crust to the outer core.

• Density increases from the least dense crust to the most dense outer core.

• Density varies randomly without a specific trend.

What is the Earth's mantle?

• The layer of the Earth located between the crust and the outer core, composed of solid rock that can flow slowly.

• The outermost layer of the Earth that is solid and rigid.

• The innermost layer of the Earth that is liquid and extremely hot.

• A layer of gases surrounding the Earth that protects it from space debris.

What material best represents the asthenosphere in a model?

• Modeling clay

• Granite

• Steel

• Concrete

How do tectonic plates move?

• They move due to the gravitational pull of the moon.

• They move due to the convection currents in the mantle, which are driven by heat from the Earth's core.

• They move as a result of the Earth's rotation.

• They move because of the pressure from the Earth's crust.
