What process is caused by some combination of wind, water flow and gravity? a. physical weathering b. erosion c. chemical weathering d. mass wasting

 B. Erosion

Explanation:

Weathering is a process of physical disintegration of the rocks or other materials present over the earth crust into small particles or sediments due to a physical agent such as water or wind. The erosion is the process of mechanical or physical removal of the top layer of the soil or any surface material and transportation of the material to the other location. Mass wasting is the process in which unstable materials get dislocate from their place due to the effect of gravity.

Erosion is caused by the combination of physical factors like wind, water and gravity.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
