World & Physical Geography MCQs

Notes:
Intrusive igneous rocks are formed from magma that cools and solidifies within the crust of a planet, surrounded by pre-existing rock (called country rock); the magma cools slowly and, as a result, these rocks are coarse-grained. Granite is the example of Intrusive Igneous rock.

Notes:
Russia is the world’s largest producers of asbestos. It is followed by China. Kazakhstan is at the third place.

Notes:
A barchan is indeed a type of dune. Characterized by its distinctive crescent shape and known to exist in arid desert environments, it faces the wind in a convex orientation. Barchans are not static; rather, they are able to shift and transform due to the predominant wind direction. This wind action contributes to their unique form and continual movement, enlightening us about the dynamic nature of desert topography.

Notes:
Venezuela meaning in Italian means “Little venice”. Little Venice is actually a district in West London. Venice is a city in Italy.

Notes:
Earth’s magnetosphere is a region of space surrounding our planet where the behavior of charged particles is largely influenced by Earth’s magnetic field. It extends far beyond the ionosphere, which is a region of the Earth’s atmosphere located from about 48 kilometers (30 miles) to 965 kilometers (600 miles) above the Earth’s surface. The magnetosphere extends into space and interacts with the solar wind, a stream of charged particles emitted by the Sun, well beyond the boundaries of the ionosphere. The boundary of the magnetosphere, known as the magnetopause, can vary in distance from Earth depending on the strength and direction of the solar wind, but it typically extends tens of thousands of kilometers into space.

Notes:
An electrojet is a streaming movement of charged particles in the lower ionosphere. Ionosphere is a region of Earth's upper atmosphere, extending from about 60 km to 1,000 km altitude. Electrojets are mainly found at altitudes between 100 to 150 km.

Notes:
In Northern Atlantic, there is a very low decrease of temperature with increasing latitudes towards north. This is because of the Gulf Stream currents which are warm currents. However, in southern Atlantic, the decrease of temperature with increasing latitude is more pronounced.

Notes:
The Biafo Glacier and the Hispar Glacier meet together to form the longest glacial system of the world. The Biafo Glacier is the world’s third longest glacier in non polar region which is 67 km long while the Hispar Glacier is 49km long, both lies in the Karakoram mountains.

Notes:
Andromeda Galaxy is also known as Messier 31. It is a barred spiral galaxy. Andromeda is the nearest major galaxy to the Milky Way.

Notes:
The Fission model was proposed by George Darwin. According to this theory, Moon is gradually moving away from the Earth, which means, that it was a part of the Earth in the past but flung outward due to the Earth’s then faster rotation.
