Evidence has proven that erosion and deposition is caused by groundwater, what process below proves this?

Biology

WARRIOR [948]3 years ago

1. The correct answer is: 3. Formation of stalagmites and stalactites .

Groundwater can be defined as a flow of water under the ground. This water is usually slightly acid, because it is formed when rainwater absorbs CO2 as it falls. That carbonic acid water sinks into the ground and moves through pores.

Groundwater dissolves away solid rock, so it is natural erosion force. As it travels through cracks, it enlarges them and potentially forms cave.

Also, groundwater carries dissolved minerals in solution that might be deposited as stalagmites or stalactites.




2. As the river flows it makes contact with soil, breaks the rocks (weathering) and carries with it sediments: gravel, sand, silt and clay (erosion).

Then, when a river encounters water, it deposits such sediments onto a flat area and forms alluvium (deposition). These sediments form several layers - beds. The delta becomes a main channel that divides land masses into streams – distributaries that look like a maze.

Reil [10]

Answer:

First, let's add the missing piece of information

A school psychologist wants to test the effectiveness of a new method of teaching FrenchFrench. She recruits 100100 firstfirst​-grade students and randomly divides them into two groups. Group 1 is taught by means of the new​ method, while group 2 is taught by traditional methods. The same teacher is assigned to teach both groups. At the end of the​ year, an achievement test​ (graded on a scale from​ 1-10) is administered and the results of the two groups are compared.

The CORRECT ANSWER IS A.

A. Group 2 serves as the control group because this group corresponds to the standard method that will be compared to the other method.

Explanation:

A control group

The control group acts as a baseline treatment that is employed in contrasting it to the other form(s) of treatments.

Ex: In this case study, a school psychologist wants to test the effectiveness of a new method of teaching French, to see if the ones taught by using a new method (are placed in group 1) do better in learning French than those taught with the traditional method (are placed in group 2). The students being taught French with the traditional method (group 2) would serve as the control group (as this is the present, proven and acceptable practice of teaching French. The factor is the method of teaching French. There are two treatments: new method and traditional method.

Therefore, the option A. is THE CORRECT ANSWER

A. Group 2 serves as the control group because this group corresponds to the standard method that will be compared to the other method.

Ivan

Answer:

A)
The loss of trees resulted in less water vapor in the atmosphere and thus less rain.

Explanation:

brainly.com/question/2889643

The primary effect of deforestation in Haiti is the loss of most of the topsoil of the region, that is, soil erosion.  

It leads to decreases in the number of trees or vegetation in the area due to which the transpiration rates decrease significantly.

It alters the water cycle and thus, reduces the rain flow.
