Row 1, Col 1 2 types of weathering Chemical & Physical

1,2 Define erosion? The movement of soil from one place to another.

1,3 How does an alluvial fan form? A stream slows down and deposits sediment on land over time.

1,4 How might erosion by groundwater create a landform? Acidic water dissolves rocks underwater to form a cavern.

1,5 What is a cavern? A cave or a chamber in a cave.

2,1 What cause a Valley to form? Running Water

2,2 Where is a delta formed? Where the river enters the ocean.

2,3 How does the gopher tortoise cause physical weathering? It moves rocks above ground where it is exposed to wind and rain.

2,4 What is groundwater? Water that is below the Earth’s surface

2,5 What is a shoreline? Where land and a body of water meet.

3,1 Why is Loess valuable? Forms good soil for faming

3,2 How is Loess formed? Dust blown by wind making layers of dust build up.

3,3 What landform is mainly created by erosion by groundwater? Underground cavern

3,4 What causes cracks in rocks to grow larger? Plant roots and ice

3,5 What mainly causes sand dunes? Wind

4,1 What would happen if the slope of a stream was increased? Water speed and erosion increase

4,2 What force mainly causes landslides, rock falls, and mudslides? Gravity

4,3 What weather condition mainly causes landslides, rock falls, and mudslides? Rain

4,4 Release acid into soil increasing chemical weathering. How do decaying leaves affect rocks in the soil?

4,5 Melting ice blocks and Sediment What is needed for kettle lakes to form?

5,1 What landform most likely formed beneath a sinkhole? Cave

5,2 Define Creep. Mass movement caused by gravity

5,3 What causes the deposition of sand at a delta? River water slowing down as it enter the ocean

5,4 What type of rock is most affected by acids? Marble

5,5 Define abrasion. A shape change due to exposure to wind/a change in size
