Answer: c. Oxygen, silicon, and aluminium
Explanation:
The common elements in the Earth's crust in order of decreasing abundance are as follows:
Oxygen: Oxygen is the most abundant element on earth's crust. It makes up 46.6%. It exists as compound of the silicate minerals. It is used for industrial, commercial and medical purposes.
Silicon: Silicon is the second most common and abundant element on the earth crust. It makes up the concentration of 27.7%. It combines with the minerals of silica to form the silicate minerals. It is used for the purpose of ceramics, cosmetics, glass and other products.
Aluminium: Aluminium is the third most common and abundant element on the earth crust. It makes up the concentration of 8.1%. The aluminum exists in the form of aluminium oxide, potassium aluminium sulfate and aluminium hydroxide. It is used for the purpose of manufacture of rockets, machinery and automobiles.
Answer:
Rain and wind will cause granite to break down and form soil over time.
Explanation:
Granite is an igneous rock, and it is one of the hardest rocks for that matter. Being an igneous and very hard rock, granite is not easy to break down and it takes a very long time, tens of millions of years in fact, and that is only if it is on the surface and exposed to the outside elements. Basically, this rock needs a very long period of time to get transformed into soil, but like any other rock it is not unbreakable and eventually, it starts to break up.
Two things that will have a big influence on the breaking up of granite would be rain and wind. The rain will cause chemical weathering while the wind will cause mechanical weathering. They will manage to gradually break up very small, fine, pieces of granite, and if they are supported by suitable climatic conditions and a lot of vegetation the process will speed up. Once the granite is broken apart and what is left of it is fine sediments, by mixing with the biomass it will form a soil.
The answer is A. resources found nearby. A topographical map is a large scale map that can be used to hike or travel since it reveals the features of the land including mountains, peaks, valleys and the sea level. None of which include resources found nearby therefore, that is the answer.

Answer:
As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases. If the humidity is at 100 percent (because it's snowing), the temperature decreases more slowly with height.
