World Agriculture, Minerals And Industries MCQ Question and Answer | Geography MCQ Question

In the Mediterranean climate off-shore trade winds doesnot blow in the summer. In summer there is a dry, warm period. Due to the movement of the sun to the top of the tropic of cancer, a warm zone or low pressure region is built on the Mediterranean region and so rain bearing winds are not seen here. But offshore trade winds blow here which don't bring much precipitation.

Chemical weathering includes Solution, oxidation and reduction. Chemical weathering is the weakening and subsequent disintegration of rock by chemical reactions.

Chemical weathering is a name given to Chemical interaction of oxygen, carbon dioxide or water with the minerals in the rocks. Chemical weathering changes the molecular structure of rocks and soil. For instance, carbon dioxide from the air or soil sometimes combines with water in a process called carbonation. This produces a weak acid, called carbonic acid, that can dissolve rock.

The climate best suited for horticulture is Mediterranean. It includes the cultivation of medicinal plants, fruits, vegetables, nuts, seeds, herbs, sprouts, mushrooms, algae, flowers, seaweeds and non-food crops such as grass and ornamental trees and plants.

Campos and Savanna are tropical grassland. Campos refers to grasslands or pastures with a vegetation cover comprising mainly grasses and herbs; scattered small shrubs and trees are occasionally found, generally by the banks of streams. A savanna is a rolling grassland scattered with shrubs and isolated trees, which can be found between a tropical rainforest and desert biome. Not enough rain falls on a savanna to support forests. Savannas are also known as tropical grasslands.

Summer rains in Australia broadly decreases from North to south. When long dry periods are interrupted by welcome periods of wet weather, the rain is more likely to fall as heavy downpours than as extended drizzle.

Although the equatorial regions have the highest annual average temperatures, the salinity in the oceans is highest near the tropics because equatorial areas receive heavy rainfall, salinity is not affected by temperature and high relative humidity in equatorial areas checks evaporation

The main reason for the formation of African and Eurasian desert belt is that It is located in the sub-tropical high pressure cells.

The Veld grassland of South Africa experiences the Steppe climate. A steppe is a dry, grassy plain. Steppes occur in temperate climates, which lie between the tropics and polar regions. Temperate regions have distinct seasonal temperature changes, with cold winters and warm summers.

Oxidation is a chemical weathering process. Oxidation is the reaction of a substance with oxygen. This is the process that causes rust. When iron in rocks reacts with oxygen, it forms iron oxide, which weakens the rock. Carbonation is the mixing of water with carbon dioxide to make carbonic acid.
