Chemical weathering is the disintegration of a substance in the rock through a chemical reaction.
Carbonation occurs when water and a pollutant, such as sulphur dioxide creates a weak sulphuric acid. When it rains and the water comes into contact with limestone a chemical reaction happens. Calcium sulphate is produced as it takes the calcium carbonate from the limestone. It can then transfer the solution to another area until it evaporates. When it does so it leaves behind calcium information such as stalactites.
hydration occurs when minerals in a rock absorb water, causing it to expand. Mineral, such as anhydrite, expands and weakens it’s structure and leave the rock more exposed to erosion.
oxidation occurs some substances react to being exposed to water or air. Iron, when exposed, will turn from a silver color to a red or dark brown color known as iron oxide. It weakens the rock.
hydrolysis occurs when water bonds with a mineral in the rock. It is particularly strong at weathering feldspars in rock and can lead to the formation of Kaolin.
Answer:
d) The lithosphere is broken into sections called plates.
Explanation:
Plate tectonics is the movement of the lithosphere and is responsible for such phenomena as volcanoes and earthquakes. The lithosphere is the exterior layer of the earth about a hundred kilometers thick. This layer is broken into large sized plates, about seven medium plates and numerous smaller plates.
These plates move a couple of inches every year from each other and are the cause of volcanoes and earthquakes.
Answer:
Most of Latin America is located in a Tropical zone that receives the Sun's direct rays yearly.
Explanation:
Latin America, as a region, has almost exclusively tropical types of climates, with Truly Cold climates lacking from the region. The closest that climates get to truly cold types are the highest parts of the Andes and the southernmost part of the region in Patagonia and Tierra del Fuego, but none of them have polar-type characteristics all year round.
This climate situation in Latin America is due to its position relative to the Equator. The Equator passes through the widest part of the region, and the vast majority of the territory north and south falls into the tropical realm, and this is also helped by the fact that north and south of the Equator the territory shrinks and the influence of the ocean is greater. The majority of the region has a tropical wet climate, savanna-like grasslands, and tropical deserts.
