Earth Science

Which landforms are results of deposition?

• Beaches and river deltas
• Bays and peninsulas
• Mountains and valleys
• Plateaus and mesas

Which statement describes a volcano erupting?

• Glacier materials are moved by gravity
• Magma is forced out of an opening in the Earth's crust
• Pressure in Earth's crust causes layers of rock to slide
• Pressure in Earth's crust becomes so great that the layers of rock buckle and fold

What is the source of heat when heat is released during an eruption?

• The Sun
• Pools of underground water
• Deep within the Earth
• Decaying plants and animals

Where does most eroded soil end up?

• In new agricultural lands
• In the desert
• In rock slides
• In the sediment of rivers

A volcanic eruption eventually produces the mountain called a volcano because...

• the crust expands due to the heat
• the magma pressure lifts up the crust
• lava and ash collect
• the plate motion folds the crust

Which is true of sand dunes?

• They are built by wind
• They are built by waves
• They are built by water carrying sediment away
• They are made by rivers cutting through land

Earthquakes can be caused by all of the following processes EXCEPT for...

• volcanic activity
• tectonic plate movement
• release of pressure along a fault line
• rocks being split apart by plant roots

Which is NOT a way that plants affect landforms?

• Cracking and splitting rocks apart
• Preventing erosion on riverbanks
• Preventing plate movement along fault lines
• Holding sand and soil in place when the wind blows

In which of the following areas would soil erosion MOST LIKELY occur?

• A forest
• Agricultural land on steep slopes
• Flat agricultural lands
• Restored prairies

Which conditions are necessary for dust storms to occur?

• wet, humid conditions
• cold, cloudy conditions
• dry, windy conditions
• hot, moist conditions
