Two of the major environmental problems facing Central America, South America, and the Caribbean are pollution, and water shortages
Answer:
As rocks on the earth go through various cycles, similarly the variation in chemical take place.
Explanation:
- As there exists a difference in the composition of minerals chemical composition from there pure forms, some variation exists in the chemical composition of elements like the size of irons, ad the temperatures at which the crystal grows.
- As rocks are an aggregate of more than one mineral they have distinct qualities like the granite is defined by the by proportions of quartz, and feldspar. Like the coal is a sedimentary rock being composed of carbon.
- The presence of oxygen, silicon, magnesium, calcium, and sodium in rocks defines their constituents, as by far Oxygen and Silicon is two of the most dominant 47% and 28%.
- An example of chemical alteration on earth is the volcanic rocks that are both igneous and metamorphic Depending on the chemical properties of these rocks the various metallic nature of elements the rocks have different temperatures and magnitudes.

Mudstone
Conglomerate
Answer: CONGLOMERATE
Explanation: Conglomerate is a rock consisting of grave or pebbles embedded in a matrix. Conglomerates typically contain finer grained sediment, e.g., either sand, silt, clay or combination of them. It takes a strong water current to transport and produce a rounded shape on particles in conglomerate.
Answer:
A. The astenosphere is denser than the lithosphere
Explanation:
The theory of isostasy is a theory that suggest that the layers of Earth are arranged in accordance to their density. It is a theory that usually refers to the mantle and crust. The mantle (astenosphere) is denser than the crust (lithosphere), so the crust floats on top of it, depending on its density, with he continental crust being higher, while the oceanic crust being lower. The two forces that are responsible for this are the gravity and buoyancy.
Answer: It's called the station model because it shows the weather measured at a particular weather station, or an area where the weather is measured. It lets meteorologists see a lot of information in a very small space. The symbols and numbers found there are the same across the world and have hardly changed in 75 years.
