2. Which of the following rocks are known as Plutonic rocks?
[A] Deep seated Intrusive Igneous
[B] Shallow depth intrusive rocks
[C] Sedimentary Rocks
[D] Extrusive igneous rocks
Show Answer
Correct Answer: A [Deep seated Intrusive Igneous]
Notes:
Extrusive igneous rocks are formed by cooling of lava on the earth’s surface. Extrusive igneous rocks are also called volcanic rocks.
Intrusive igneous rocks are formed when magma solidifies below the earth’s surface.
Deep seated intrusive rocks are termed as plutonic rocks.
Shallow depth intrusive rocks are termed as hypabyssal.
3. Pine trees are generally found in which type of climate?
[A] Wet Deciduous
[B] Coniferous
[C] Tundra
[D] Monsoon

Notes:
Aluminum is the most abundant metal in the Earth’s crust, making up about 8.1% of the crust. However, it’s rarely found in its pure form in nature. Instead, it’s usually found combined with other elements in minerals like bauxite and cryolite. Two common aluminum compounds are alum and aluminum oxide. The most abundant non-metal in the Earth’s crust is oxygen, which makes up about 46% of the crust.

7. The Roaring Forties are strong westerly winds found in between:
[A] horse latitudes in southern hemisphere
[B] sub polar region in northern hemisphere
[C] polar high region of northern hemisphere
[D] 40 and 50 degrees latitudes in southern hemisphere
Show Answer
Correct Answer: D [ 40 and 50 degrees latitudes in southern hemisphere]

8. If the difference in time of the two places is 2 hours and 20 minutes, then what would be the difference in their longitudes?
[A] 30°
[B] 35°
[C] 40°
