World & Physical Geography MCQs

Notes:
During Volcano Molten lava erupted from the earth’s interior, support that temperature increases towards the centre of the earth. The temperature at the centre is estimated to lie somewhere between 3000°C and 50000C.

Notes:
Mars is known as the red planet because it looks red from Earth. The reddish color comes from high concentration of iron oxide compounds that is rust—in the rocks of the Martian surface.
Phobos and Deimos are the natural satellites of Mars.

Notes:
Tundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturi, meaning treeless plain. It is present in the frost-molded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. It is a treeless biome.

Notes:
Eskimos live in the tundra climate. The tundra is part of the polar region, which is characterized by a frigid climate. The polar region includes the Arctic and the Antarctic. Eskimos are indigenous people who have traditionally lived in the northern circumpolar region. This region includes eastern Siberia, Alaska, Canada, and Greenland. Eskimos live in igloos during the winter and portable huts in the summer. The word “igloo” is the Eskimo word for “house”. Eskimos have developed unique skills and adaptations to survive in the extreme cold climates.

Notes:
Volta River Project is located in Ghana. The Volta River is the main river system in Ghana. The Volta River Project was planned by Ghana’s first president, Kwame Nkrumah, as part of an industrial program to transform Ghana into an industrialized country. The Volta River Project includes the Akosombo Dam, also known as the Volta Dam. The Akosombo Dam is a hydroelectric dam on the Volta River in southeastern Ghana. The dam was completed in 1965 and is 124m tall and 660m long. The dam holds back the waters of Lake Volta, the largest man-made lake in the world by surface area. The Lake Volta reservoir covers a third of Ghana’s land area.

Notes:
A rift valley is a long, narrow valley that forms where the Earth’s crust is being pulled apart and is typically associated with the process of continental rifting. Rift valleys are often found along the boundary between two tectonic plates, and they are typically steep-sided and bounded by faults. As the plates move apart, the ground between them sinks, forming a depression that eventually becomes a valley. This process can take millions of years, and over time, the rift valley can become filled with sediment and other materials, forming a lowland area.

Notes:
“Lithium triangle” is a group of three South American countries viz. Chile, Argentina and Bolivia. These three have much of the world’s lithium deposits. Countries nowadays in order to cut the emissions are relying on alternative fuels for petrol and diesel. Lithium-ion battery is one of the most preferred options for electric vehicles. To meet its target of becoming 100 per-cent e-vehicle nation by 2030, India is highly dependent on import of lithium-ion batteries.

Notes:
A caldera is a volcanic feature formed by the collapse of a volcano into itself, making it a large, special form of volcanic crater. A caldera collapse is usually triggered by the emptying of the magma chamber beneath the volcano, as the result of a large volcanic eruption.

Notes:
The areas between 20 ° -30 ° latitude on western margins of continents are the regions of descending air. Because of this, the air gets compressed and warm as it descends and thus the moisture keeps decreasing.

Notes:
Daily weather map showing isobars is an example of isopleth map. Isopleth map is a map that uses lines or colors to indicate areas with similar regional aspects. Isopleth maps may use lines to show areas where elevation, temperature, rainfall, or some other quality is the same; values between lines can be interpolated.
