Review weathering, erosion, deposition for cqa

Look at the picture of the rock formation, Many years ago the rock cliff above was much larger and rougher. What kinds of

slow changes most likely caused it to change over time?

• Lightning hit the cliff, causing it to break apart and deposit the pieces at the

  bottom of the cliff.

• Wind, water, and ice shaped and re-shaped the face of the cliff causing it to

  become smoother, and depositing the pieces at the bottom of the cliff.

• High temperatures and rising barometric pressure caused the rock face of the

  cliff to break apart into smaller pieces.

• A glacier passed over the land, depositing the pieces at the bottom of the

  cliff.

How do plants most commonly break large rocks into smaller pieces?

• Plant leaves protect rocks from very cold and very hot temperatures.

• Plant roots grow into cracks in rocks

• Seeds from plants fall onto rocks and release acid

• tems of plants surround and squeeze rocks

Which of these events cause rapid changes on the Earth's surface?

• weathering and earthquakes

• weathering and volcanoes

• earthquakes and volcanoes

• wind and erosion

A canyon is a large, deep valley that is carved into rock over a long period of

time. Which of the following most likely causes a canyon to form?

• deposition

• moving water

• earthquake

• volcano

Which of the following can be caused by glaciers?

• moving rocks and boulders

• forming lakes

• scraping rocks

• all of the above

If you drove on a road that looked like the picture above, what force would you

guess most likely made the changes in the Earth's surface?

• Snowstorm

• Glacier

• Earthquake

• Volcano

Some process that shape Earth's surface are slow. Other processes are rapid

(fast).

Which statement describes a rapid (fast) change?

• Earthquakes move land and rock.

• Glaciers melt and form rivers.

• Wind weathers rocks into sand.

• Rivers carry sediment and build deltas.

The rocks in the picture above were under the Earth's surface for many thousands

of years. Which type of weathering is most responsible for revealing these rocks

on Earth's surface today?

• Mountain building

• varying cloud conditions

• Growing plants

• Wind and rain

What event caused the change in the Earth's surface in the picture ?

• Tornado

• Tidal waves

• Volcanic Eruptions

• Landslide
