Weathering and Erosion

What is weathering?

• The process by which
  water, ice, wind or gravity
  moves fragments of rock
  and soil.
• The process by which
  water, ice, wind or gravity
  deposit rock sediments
  and soil in a new place.
• The breaking down of
  Earth’s crust into smaller
  and smaller pieces.

What is erosion?

• The process by which
  water, ice, wind or gravity
  moves fragments of rock
  and soil.
• The process by which
  water, ice, wind or gravity
  deposit rock sediments
  and soil in a new place.
• The breaking down of
  Earth’s crust into smaller
  and smaller pieces.

The diagrams  shows a natural process that weathers rock.
 Which statement best explains why this process results in weathering?

• frozen water acts as a solute
• water expands when it freezes
• the mass of water increases when it freezes
• frozen water dissolves most types of rock

How do plants weather rocks?

• during photosynthesis
• when roots grow into cracks of rocks and expand the rock
• when the plant moves water from the roots to the leaves

the process in which sediment particles are picked up and moved from one place to another

• mechanical weathering
• chemical weathering
• erosion
• deposition

These rocks were broken apart from the continuous freeze/thaw of water in the cracks of the rocks. This is an example of:

• ice wedging
• acid rain
• permeability
• abrasion

• true

• false

What is the end product of erosion?

• rocks

• sediment

• gravity

• canyons

physically breaking down rocks into smaller fragments is called

• chemical weathering

• mechanical weathering

• erosion

• abrasion
