Mass Wasting, Surface & Underground Features

What is the main force responsible for mass wasting?

• Wind

• Gravity

• Water pressure

• Tectonic activity

Which type of mass movement occurs when a block of rock moves downward along a curved surface?

• Rockfall

• Creep

• Slump

• Mudflow

Which of the following conditions can increase the likelihood of mass wasting?

• Heavy rainfall

• Earthquakes

• Deforestation

• All of the above

A slow, gradual downhill movement of soil and rock that is hardly noticeable is called:

• Avalanche

• Soil creep

• Debris flow

• Landslide

What is the difference between a landslide and a mudflow?

• A landslide moves slowly, while a mudflow moves rapidly.

• A mudflow contains a high amount of water, while a landslide does not.

• A landslide only occurs in deserts, while mudflows occur in forests.

• Mudflows occur due to tectonic activity, while landslides occur due to gravity.

Which landform is created by river erosion on the Earth's surface?

• Cave

• Valley

• Stalactite

• Geyser

Sinkholes are formed due to:

• Volcanic eruptions

• Earthquakes

• The collapse of underground limestone caves

• Wind erosion

Which of the following is an underground feature formed by deposition?

• Stalactites

• U-shaped valley

• Delta

• Moraine

Which of the following is an example of an erosional feature?

• Sand dunes

• Waterfalls

• Stalagmites

• Delta

What is the term for a natural underground chamber formed in limestone regions?

• Gorge

• Basin

• Cave

• Ridge
