Weathering is the process by which rocks are broken down into smaller particles as a result of physical and chemical changes that are occurring in them. There are three major types of weathering these are: physical, chemical and biological weathering.
For the question given above, the type of weathering that is occurring in the picture of the given rock is PHYSICAL WEATHERING.
Physical weathering is the type of weathering in which the affected rock is changed in size and shape by means of some agents. The broken particles are usually of the same composition as the parent rock. The agents of physical weathering include: ice, plant roots, animal activities, abrasion and exfoliation. Physically weathered rocks are usually round in shape as a result of the abrasion process which they have undergone.<span />
Answer:
Wegener presented a number of evidence to prove his plate tectonic theory, such as :
- The matching of rocks on each side of the Atlantic Ocean like a puzzle.
- His knowledge hat organisms such as freshwater reptiles were found in almost all continents
- He also identified organisms that live in different continents, and could not possibly cross over to the other continents due to water bodies (oceans) separating the continents.
Wegener's plate tectonic theory caused doubts to other scientists, because of the way he presented his evidence. Other scientists considered his mechanisms unrealistic
Explanation:
Answer:
precipitate
Explanation:
In case of an inorganic chemical reaction leading to precipitation, the chemical reagent causing the solid to form is called the precipitant. The clear liquid remaining above the precipitated or the centrifuged solid phase is the ' supernate' or ' supernatant'.
Answer:Our ancestors’ perception of taste was important for survival and thriving. Now researchers are trying to produce food with reduced calories or salt that remains palatable
Explanation:
Evolution of taste
Our ancestors had to seek out their food from the environment, and their perception of taste was important for survival and thriving. ... They work with foods that are being produced in a manner that reduces calories or salt or adds ingredients with potential health benefits from plants
