Weathering - CORRECT ANSWER-Breaking of rock/land into sediments; ice
wedging, carbonic acids
Erosion - CORRECT ANSWER-Movement of sediments by wind, water, gravity
or glaciers
Deposition - CORRECT ANSWER-Dropping off of sediments in a new location
like a sand dune
Rivers when they first begin are almost completely straight. Over time rivers
develop more curves and bends. Explain why this happens. - CORRECT
ANSWER-The moving water erodes the banks of the river. As the river curves it
slows down. The slowing down of the river causes deposition. The dropped
sediments build up, causing the river to curve even more.
Explain the process of ice wedging. - CORRECT ANSWER-Rain seeps into the
cracks of rocks / cement / or a road. As the temperature drops the water freezes.
The water expands as it freezes. The expansion pushes the rock apart and
makes the crack bigger. The repeated rain, freezing, and thawing increases this
effect.
Vegetation helps to slow erosion. Explain 2 ways vegetation could slow erosion. -
CORRECT ANSWER-Vegetation / plant roots hold the soil in place; this reduces
erosion by runoff. Trees trunks at the edge of a forest slows the wind by blocking
it.
Explain what abrasion is. - CORRECT ANSWER-Abrasion is a process that
wears away by friction (like sand paper). Wind can carry small sediments that
can hit statues. Over time this could cause the words not to be readable.
Carbonic acid x - CORRECT ANSWER-C
Animal burrowing x - CORRECT ANSWER-M
