PLZ help me I will give brainest Alexis knows that different forms of water can affect erosion differently. She wants to build a model to compare different forms of water.

How could she build a model to compare how different forms of water cause erosion on a hill?

1. Obtain two identical containers and dry sand.

2. Shape equal amounts of sand into a
(A) slope on the side of each container
(B) flat layer in each container

3. Spray water on the sand in one container. The sprayed water represents
(A) a flowing river
(B) ocean waves
(C) rainfall

4. In the other container,
(A) do not add water. this represents the lack of water erosion
(B) place ice cubes to melt on the sand. this represents snow or glaciers

Analyze differences between the two containers.

glacial erosion, the picking up and movement of earth beneath a glacier, is also referred to as plucking. erosion and transportation of individual pieces of bedrock, especially large "joint block occur as a result of this glacial erosion. plucking is type of erosion in which rocks become frozen into the bottom and sides of the glacier.as the glacier moves downhill it 'plucks' the rocks frozen into the glacier from the ground.

in the year 2850, humans successfully colonized mars. the martian modules that were constructed could hold only a small population of people. it is now a century later, and the population on mars has grown to 600 people. of the current mars population, 45 people express the recessive phenotype for phenylketon- uria (pku) syndrome (pp genotype).

explanation:

airlines i think? or a cruise boat? does this work out for u? ?
