Answer 1

erosion and weathering

Step-by-step explanation:

Weathering

Atmospheric agents act on the outermost layer of the earth's crust by altering or eroding rocks and minerals, and converting them into different fragments or residues that can be transported and sedimented. This process is carried out in two ways: through a physical action (mechanical or disintegration) and another chemical (decomposition or alteration), although depending on the climate of each region, one or the other may predominate; The set of these actions is called weathering. These definitions may vary depending on the authors; In some cases, weathering is considered to be the product of chemical action, while physical action consists only of disintegration.

As mentioned, weathering produces fragments of rocks and minerals, as well as other residual and soluble products, which can be transported and deposited at other levels, leaving new surfaces exposed to weathering. This process is so linked to the concept of erosion that in many cases they are considered synonyms

Erosion

It is the natural process of a physical and chemical nature that continuously wears and destroys the soils and rocks of the earth's crust; They include material transport but not static weathering. Most erosive processes are the result of the combined action of several factors, such as heat, cold, gases, water, wind, gravity and plant and animal life. Some of these factors predominate in some regions, such as wind in arid areas. Depending on the main causative agent of erosion and the time that its effects on the earth's surface take to manifest itself, there is talk of geological or natural erosion and accelerated erosion. The first is due to the action of natural agents and processes that act over millions of years; while accelerated erosion is the result of anthropic action and its effects are felt in a much shorter period of time.

Answer 2

Answer: Weathering and Erosion

Step-by-step explanation:

Sedimentary rocks are formed from sediments and deposits of particles of various types, forms and sizes that are transported by air, wind or water, and then subjected to chemical processes to become rocks. These types of rocks are usually found in the form of layers or strata in places where sediment accumulates due to the erosion of other materials, for example on the banks of rivers, in valleys, lakes (and any other type of body of water).

In this sense, the processes that contribute to the formation of a sedimentary rock are Weathering and Erosion .

Weathering refers to the set of destructive processes through which rocky materials go trhough, that cause changes in the color, texture, composition, firmness and shape of the material. This happens when the rocks come into contact with atmospheric agents such as oxygen and carbon dioxide.

On the other hand, Erosion is the wear that occurs caused by external agents, mainly by wind and water, although other factors such as continuous friction with other surfaces and debris, and the action of living beings (including humanity) affect.
