Earth Science Review

Earth is made of different layers that have varying characteristics. Which is the thickest layer?

• the mantle

• the inner core

• the outer core

• the crust

Which is a process that most likely formed the Appalachian Mountains found in the eastern part of North America?

• earthquake

• folded rock

• plate tectonics

• volcanic activity

Which statement about the formation of rocks is true?

• Heat and pressure can change igneous rock to sedimentary rock.

• Weathering and erosion can change sedimentary rock into sediment.

• Heat and pressure cause metamorphic rock to weather and erode.

• Weathering and erosion prevent magma from changing into igneous rock.

What is the driving force behind the movement of tectonic plates?

• tidal forces

• convection currents in Earths mantle

• Gravitational pull of the Sun and the Moon.

• the different rotation of Earths inner and outer cores.

The Appalachian Mountains, which extend from Canada to Alabama, were much taller in the past than they are today. Which of the following two processes are most responsible for the decrease in the height of the Appalachian Mountains?

• sedimentation and flooding

• weathering and erosion

• volcanic eruptions and landslides

• tectonic collisions and earthquakes

The topsoil covering an area of land was washed away by rain. Which statement best describes the land?

• steep, without vegetation

• steep, with vegetation

• Flat, without vegetation

• flat, with vegetation

Which BEST explains the movement of tectonic plates?

• They move several miles each year because of convention within Earth.

• They move several centimeters each year because of convection within Earth.

• They move several feet each year because of convection within Earth.
