Consider the following statements regarding World Distribution of Sea Level Pressure.
1.High-pressure areas along 30° N and 30° S are known as the subtropical highs.
2.Near the poles the pressure is low and it is known as the polar lows.
Which of the above statements is/are correct?
Correct
Solution: a)
World Distribution of Sea Level Pressure:
Near the equator the sea level pressure is low and the area is known as equatorial low. Along 30° N and 30° S are found the high-pressure areas known as the subtropical highs. Further pole wards along 60 degree N and 60 degree S, the low-pressure belts are termed as the sub polar lows. Near the poles the pressure is high and it is known as the polar high.

Which of the following rivers flow through a rift valley?
1.Damodar
2.Mahanadi
3.Narmada
4.Tapti
Correct
Solution: b)
A rift valley is a lowland region that forms where Earth’s tectonic plates move apart, or rift. Narmada flows in a rift valley flowing west between the Satpura and Vindhya ranges.
The other rivers which flow through rift valley include Damodar River in Chota Nagpur Plateau and Tapti. The Tapti River and Mahi River also flow through rift valleys, but between different ranges.

In geological history of the earth, Panthalasa was a
Correct
Panthalassa was the super-ocean that surrounded the supercontinent Pangaea, the latest in a series of supercontinents in the history of Earth. During the Paleozoic–Mesozoic transition it occupied almost 70% of Earth’s surface. Its ocean floor has completely disappeared because of the continuous subduction along the continental margins on its circumference. Panthalassa is also referred to as the Paleo-Pacific (“old Pacific”) or Proto-Pacific because the Pacific Ocean is a direct continuation of Panthalassa.

1.Silicon
2.Iron
3.Aluminium
4.Calcium
5.Magnesium
Select the correct answer code:
Correct
About 98 per cent of the total crust of the earth is composed of eight elements like oxygen, silicon, aluminium, iron, calcium, sodium, potassium and magnesium, and the rest is constituted by titanium, hydrogen, phosphorous, manganese, sulphur, carbon, nickel and other elements.

Question 9 of 10
9. Question

Consider the following statements.
1.More diversity of landforms can be observed in oceans than continents.
2.Continental crust is denser than ocean crust.
3.Pacific Ocean is the largest ocean and it is almost equal to the area of all other oceans combined.
Which of the above statements is/are correct?
Correct
Continental crust is less dense than ocean crust as the latter is made of basaltic rocks. The main constituents of the Continental crust are Silica and Aluminium; and that of the ocean crust are Silica and Magnesium.
Although Pacific Ocean is the largest ocean than other oceans, its area is far lesser than all other oceans area combined.

According to Wegner, which among the following forces could be responsible for continental drift?
Correct
According to Wegener, all the continents formed a single continental mass, a mega ocean surrounded by the same.
He argued that, around 200 million years ago, the super continent, Pangaea, began to split.
Wegener suggested that the movement responsible for the drifting of the continents was caused by pole-fleeing force and tidal force.
