Weathering Erosion Deposition

Which of the following are landforms created by deposition? Multiple answers (WED Notes)

• flood plain

• delta

• beaches

• arch

• hoodoo

Which of the options below describe mechanical weathering. Multiple answers (WED Notes)

• plant roots pry apart cracks in rocks & cause crumbling

• water freezes in cracks, expands, and causes rock to break apart

• pollution forms acid rain which wears away rocks and statues

• process that breaks down rocks by changing them into new compounds

• physically breaking rocks into smaller pieces

Granite on a mountaintop is likely to erode differently than granite found on a sea cliff. Why is this statement true? (A12)

• Granite on a mountaintop will erode faster than the cliff because it is exposed to waves

• Granite on a cliff will erode faster than a mountaintop because it has a high elevation

• Granite on a cliff will erode faster than a mountaintop because it is exposed to rain/flowing water and waves

• Granite on a mountaintop will erode faster than the cliff because it is exposed to rain/flowing water

What is the landform that is shown on the far right side of the topographical map? (A10, Gizmo Topo Maps)

• valley

• river

• mountain

• flat plain

Why is weathering important to the process of erosion? (A13)

• If weathering does not happen there is no sediment for erosion.

• If erosion does not happen, then weathering cannot happen.

• If weathering happens, erosion cannot happen.

• If erosion happens, then weathering cannot happen.

Why does erosion lead to deposition? (A13)

• Because mechanical weathering happens more than chemical weathering

• Because chemical weathering happens more than mechanical weathering

• Because the erosion agent never stops or slows down

• Because the erosion agent always stops or slows down

Which of the following is NOT a problem that the city of New Orleans faces as a result of its location on the banks of the Mississippi? (A14)

• flood risk

• loss of wetlands

• river drying up

• sinking land

How could the movement of sediment cause a problems? Match the problems with the landform (A7)
A. river sediment moves downstream to mouth & deposits tremendous amounts loose soil
B. undercutting moves sediment & houses collapse

C. mudslides from unstable land deposit sediment on houses below

• A. Cliff

  B. Hill

  C. Marsh

• A. Hill
  B. Marsh
  C. Cliff

• A. Marsh
  B. Cliff

  C. Hill

As a river gets older, its becomes curvier due to erosion and deposition patterns.

• TRUE

• FALSE

Which of the options below describe chemical weathering. Multiple answers (WED Notes)

• oxygen causes rust to form which weakens & breaks rocks apart

• water freezes in cracks, expands, and causes rock to break apart

• physically breaking rocks into smaller pieces

• pollution forms acid rain which wears away rocks and statues

• process that breaks down rocks by changing them into new compounds
