Earth Layers and Rock Cycle Review

Earth has a magnetic field that protects us from ultraviolet rays and space debris. This is possible due to which of the following statements?

• The swirling of the liquid metal in the INNER core inside of the Solid Outer core.

• The convection currents in the magma of the mantle.

• The extreme heat in the inner core.

• The swirling of liquid metal in the outer core that surrounds the solid inner core.

What characteristics describe the mantle?

• The layer that makes up the all of the tectonic plates.

• Consists of the asthenosphere and convection currents, and is the thickest layer of Earth.

• The liquid layer responsible for Earth's magnetic field.

• The hottest layer made of solid iron.

Which of the following are characteristics of oceanic crust?

• Oceanic crust is mostly watery granite.

• Oceanic crust is what makes up the silicon beaches.

• Oceanic crust is mostly basalt and makes up the ocean floor.

• Oceanic crust is the oldest crust.
