Vocabulary Word

100

• - the longest day of the year= maximum intensity of the sun’s rays & most hours of sunlight.

Summer solstice

200

• a scientific theory that explains how major landforms are created as a result of Earth's subterranean movements.

Plate tectonics

300

the mostly solid bulk of Earth's interior. The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84 percent of Earth's total volume.

Mantle-

Short answers

100

what is convergent?

It is where crust comes together; one crust is destroyed as it dives under another, known as subduction.

200

What are the major landforms?

Mountains, plains, plateaus, hills

300

What are some minor landforms?

valleys, bays, deltas, continental shelf, deserts, islands, sand dunes, basins, peninsulas, glaciers, etc.

400

How are volcanoes formed?

A volcano is formed when plate tectonics move away from each other at a divergent boundary and creating a gap for the magma to rise and is hardened and cooled down when in contact with water, by cool air, or when surfaced.

500

How does weathering affect the shape of a rock?

Rocks can dissolve and breakdown when in contact with strong winds, rain, air, and changes in temperature. For example, a rock can easily breakdown, dissolve, or erode when it rains after a long period of without rain since the rock is completely dry and its minerals and soils are easily carried away.

True or false

100

Fault lines are created when 2 plates slide past each other.

True

200

Mountains are created at a convergent boundary when plates are pushed together.

True

300

Divergent boundary where neither crust is produced nor destroyed as the plates slide horizontally past each other.

False. Transform boundaries is the correct answer.

400

Transform boundary is where crust comes together; one crust is destroyed as it dives under another, known as subduction.

False. Convergent boundary is the correct answer.

500
