Q3:

Changes to the surface of Earth can happen quickly or slowly. Which of the given changes is a slow change?

  • AErosion
  • BA landslide
  • CAn earthquake
  • DA volcanic eruption

Q4:

Antelope Canyon-72 ppi
  • AWind
  • BFlood water
  • CSnow

Q5:

Q6:

The coastline shown in the image has been eroded by the ocean. Would this change occur quickly or over a long period of time?

  • AOver a long period of time
  • BQuickly

Q7:

The photograph shows the Perito Moreno Glacier in Argentina. How do glaciers cause erosion of the land?

The Perito Moreno Glacier in Argentina - 72 ppi
  • AAs glaciers move, pieces of rock freeze to the glacier and are carried away.
  • BAs glaciers move, they push the land apart and create valleys.

Q8:

The surface of Earth is changing all the time. Erosion can change the shape of the land over time. What is erosion?

Earth equirectangular
  • AWhen rocks and minerals are broken apart or worn away.
  • BWhen rocks, minerals, and soil are moved to a new place.

Q9:

The photograph shows part of the Grand Canyon. How was the Grand Canyon formed?

Grand Canyon National Park-72 ppi
