Acid rain has worn away some features on this statue. What type of weathering is this?

erosion

mechanical/physical weathering

deposition

chemical weathering

Help please

Answers

Answer: Chemical Weathering

Explanation:

This type of weathering is called chemical weathering.

What is chemical weathering?

Chemical weathering is a type of weathering that occurs when chemical reactions break down and alter the structure of rocks and minerals. This can happen through processes such as oxidation, hydrolysis, and acid-base reactions.

Chemical weathering can be caused by various factors, including water, air, and temperature. For example, when rainwater containing carbon dioxide dissolves in the soil, it forms carbonic acid, which can chemically break down rocks. Chemical weathering can also lead to soil formation and the release of nutrients that are important for plant growth. Over time, this process can change the appearance and composition of the landscape, affecting not only the geology but also the ecology of the area.

The graph shows carrying capacity in two different areas for two populations
of salmon. Which statement below is most likely true about these areas?

A. Changes in the aquatic environment in Area A has made it less hospitable to salmon

B. More food resources are available for salmon in Area B than in Area A.

C. Salmon fishing occurs in Area B but not in Area A.

D. More species compete with salmon for food in Area A than 1 Area
B.

Answers

Answer:

C ,salmon fishing occurs in area b but not in area a

The statement which is most likely true about these areas is that the salmon fishing occurs in the area B but not in the area A. Thus, the correct option will be C.

What is Carrying capacity?

Carrying capacity can be defined as the species' average population size which can stay in a particular environmental habitat. The species population size in an atmosphere is limited by the environmental factors such as adequate food, shelter, water, and the mates as well. If these needs are not met correctly with the surrounding, then the population will decrease until the resource rebounds and then the species number is restored.

From the given graph which is showing carrying capacity in two different areas of two populations of salmon fishes. The statement which is most likely to be true about these areas is that salmon fishing occurs in the areas B but not in area A.

Therefore, the correct option will be C.

Examine the cladogram; What is one shortcoming of this proposed family tree?

Answers

Although we do not have access to the diagram in question, we can say in general terms that cladograms are used to study the ancestral relationship of organisms based on physical traits and phenotypes.

Why is a cladogram not very effective?

The major shortcoming produced by a cladogram is its lack of genetic factors. Cladograms focus on comparing organisms based solely on phenotypes and physical traits, which results in errors due to ignorance of genetic factors which would allow for more precise results.

Therefore, we can confirm that cladograms are used to study the ancestral relationship of organisms based on physical traits and phenotypes, and their shortcoming is the lack of genetic factors.
