True.

Show me with your hands, how do convergent plates move?

Towards eachother

Which two processes could result in the formation of high mountains with well-rounded peaks?

(a) volcanic eruptions and global warming

(b) earthquakes and tidal activity

(c) collision of crustal plates and erosion

(d) production of greenhouse gases and weathering

(a) volcanic eruptions and global warming

What caused the formation of mountain ranges?

(a) erosion of continental coastlines by ocean waves (b) collision of tectonic plates

(c) deposition of river sediments entering the ocean (d) uneven heating of Earth’s surface

(b) collision of tectonic plates

Which Earth layer contains soft rock that are believed to be responsible for the movement of Earth’s tectonic plates?

(a) crust 

(b) outer core

(c) mantle

(d) inner core

(c) mantle

True or False: The plates of the outer layer move

True

200

Show me with your hands, how do divergent plates move?

Away from each other

Similar rock formations have been discovered in the United States and Portugal. These rock formations were formed at the same time and are made of the same types of rocks. What could explain how these rocks got so far apart?

The United States and Portugal are parts of different plates. The plates slowly moved far apart as soft, solid rock from underneath got added to the edges of the plates over millions of years.

Name two geologic features or events that might result from the movement of crustal plates.

Earth quakes

Mountains

Volcanoes

How does the thickness of Earth’s oceanic crust compare to the thickness of the continental crust?


  • Continental crust is considerably thicker

300

True or False: Earth’s outer layer is divided into sections called puzzles.

False, they are divided into sections called plates.

300

Show me with your hands, how do transform plates move?

Heading in opposite directions and passing each other 

300

Similar rock formations have been discovered in the United States and Morocco. These rock formations were formed at the same time and are made of the same types of rocks. What could explain how these rocks got so far apart?

The United States and Morocco are parts of different plates. The plates slowly moved far apart as soft, solid rock from underneath got added to the edges of the plates over millions of years.

300

What location on Earth’s surface where volcanoes are most likely to form?

Volcanoes are most likely to form at the boundaries between tectonic plates. When one plate collides with another mountains are formed. When one plate slides under another, the plate going underneath gets melted by the hot interior of the Earth.

A team of engineers wants to study hard, solid rock under the surface of Earth. The team is considering drilling down in South Korea (1) and in the Yellow Sea (2). Where will the team find hard, solid rock?

under 1 and 2, because Earth’s entire outer layer is made of hard, solid rock

400

Which statement best describes Earth’s outer layer underneath the surface in the image?

a Underneath the soil, Earth’s outer layer is made of water.

b Underneath both the soil and the ocean, Earth’s outer layer is made of sand and water.

c Underneath the soil, Earth’s outer layer is made of hard, solid rock. Underneath the ocean, Earth’s outer layer is made of sand.

d Underneath both the soil and the ocean, Earth’s outer layer is made of hard, solid rock.

d Underneath both the soil and the ocean, Earth’s outer layer is made of hard, solid rock.

What happens are divergent plate boundaries?

a.) rock rises from the mantle and hardens, adding new solid rock to the edges of both plates.

b.) one plate moves underneath the other plate and sinks into the mantle.

a.) At divergent plate boundaries, rock rises from the mantle and hardens, adding new solid rock to the edges of both plates.

  1. Fossil formation is generally caused by 

(a) wind

(b) evaporation 

(c) volcanic activity 

(d) an organism being buried by sediment

(d) an organism being buried by sediment

400

How does the Theory of Plate Tectonics explain the location of the fossils found in South America and Africa?

(a) The continents were once joined together.

(b) The animals were able to swim from one continent to the other.

(c) Humans transported the animals from point A to point B.

(d) The animals developed independently on both continents.

(a) The continents were once joined together.

True or False: Earth’s plates move on top of a soft, solid layer of rock called the crust.

False, it is called the mantle

Which statement best describes Earth’s outer layer underneath the surface?

a) Underneath the soil, Earth’s outer layer is made of hard, solid rock. Underneath the ocean, Earth’s outer layer is made of sand.

b) Underneath both the soil and the ocean, Earth’s outer layer is made of hard, solid rock.

c) Underneath the soil, Earth’s outer layer is made of water.

d) Underneath both the soil and the ocean, Earth’s outer layer is made of sand and water.

b.) Underneath both the soil and the ocean, Earth’s outer layer is made of hard, solid rock.

What happens are convergent plate boundaries?

a.) rock rises from the mantle and hardens, adding new solid rock to the edges of both plates.

b.) one plate moves underneath the other plate and sinks into the mantle.

b.) At convergent plate boundaries, one plate moves underneath the other plate and sinks into the mantle.

500

Why are fossils of species that once lived together found in different locations on Earth now?

The plates slowly moved far apart as soft, solid rock from underneath got added to the edges of the plates over millions of years.
