World & Physical Geography MCQs

Notes:
The Java Trench—contrary to the other options—is not situated within the Pacific Ocean; it actually lies within the Indian Ocean. Trenches are long, narrow, steep-sided depressions in the ocean floor, most of which culminate in the Pacific Ocean. However, the Java Trench, which is considered the deepest point in the Indian Ocean, makes for a notable exception to this majority.

Notes:
If the earth stops rotating, then the impact of weight of a body will be minimum on the Poles. The maximum weight will be a t equator. If the earth stops rotating then there would be no centrifugal force whose direction is away from the core. Thus the force due to gravity is not minimised at all and this in turn increases an object’s weight at the equator.

Notes:
Europa is an icy moon of the planet Jupiter. It has long been a high priority for its exploration because it holds a salty liquid water ocean beneath its icy crust. The ultimate aim of NASA’s Europa Clipper mission is to determine if Europa is habitable.

Notes:
Cinder cones are a type of volcano. They are the simplest and most common type of volcano. Cinder cones are also known as ash cones. They are formed by pyroclastic fragments, such as volcanic ash, solidified lava, and hot gases. These fragments are ejected from a single vent. As the gas-charged lava is blown into the air, it breaks into small fragments that solidify and fall around the vent. These fragments form a circular or oval cone.
Cinder cones are never huge and have a slope of around 33 degrees. They can be new volcanoes, or they can form over the vents of pre-existing volcanoes. They only grow to about a thousand feet, the size of a hill.

Notes:
Russia has the largest natural gas reserves in the world, with 38 trillion cubic meters (1,341 trillion cubic feet). This is equivalent to about 19% of the world’s total reserves. Russia exports 26% of its gas production to other countries. The Arctic accounts for over 80% of Russia’s natural gas production.

The top five countries with the largest natural gas reserves are:

1. Russia
2. Iran
3. Qatar
4. USA
5. Saudi Arabia

The world has proven reserves equivalent to 52.3 times its annual consumption. This means it has about 52 years of gas left at current consumption levels.

Notes:
Fluvial landform are shaped by running water (overland flow and stream flow). Fluvial processes are most important of all the exogenetic processes as landform associated with them have overall dominance in the environment of terrestrial life

Notes:
Fossils are found in Sedimentary rocks. Conglomerate is a sedimentary rock. Marble and Gneiss are metamorphic rocks. Granite is an intrusive igneous rock.

Notes:
First statement is incorrect because the time difference between any two lines of longitude is of four minutes. Second statement is correct.

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:
Sun and our whole solar system orbit around the center of the Milky Way Galaxy. These are moving at an average velocity of 828,000 km/hr. But even at that high rate, it still takes about 250 million years to make one complete orbit around the Milky Way.
