Ans: (b)

Explanation:

• The Moon was formed from a collision between Earth and a Mars-sized celestial body called Theia. This statement is true and supported by the Giant Impact Hypothesis, which suggests that the Moon was formed when a Mars-sized object collided with the early Earth. The impact ejected material into space, which eventually coalesced to form the Moon.
• The Moon was formed before the Earth. This statement is false. The Moon is believed to have formed around 4.5 billion years ago, shortly after the formation of the Earth. It was not formed before the Earth.
• The Moon’s composition is identical to that of the Earth’s mantle. This statement is false. While the Moon’s composition is similar to the Earth’s in some aspects, it is not identical to the Earth’s mantle. The Moon has a lower iron content and lacks certain volatile elements found in the Earth’s mantle.
• The Moon’s gravitational pull affects Earth’s tides. This statement is true. The Moon’s gravitational force, along with the Sun’s gravitational force, influences the ocean tides on Earth. The gravitational interaction between the Moon and the Earth causes the water on the side facing the Moon to bulge, creating high tides, while the opposite side experiences low tides.

Ans: (c )

Explanation:

• Dust storms are typically characterized by strong winds that pick up and carry large amounts of dust and sand particles. These storms commonly occur in arid or semi-arid regions where dry conditions and loose soil or sand are present. The absence of sufficient vegetation to anchor the soil also contributes to the formation of dust storms. While rainfall can have some impact on dust storm activity by temporarily dampening the soil and reducing the dust particles’ ability to become airborne, excessive rainfall is not the primary cause of dust storms. Similarly, coastal areas with high humidity are less likely to experience dust storms since the presence of moisture helps to weigh down the particles and prevents them from being easily picked up by the wind. Volcanic eruptions can release significant amounts of ash and dust into the atmosphere, but they are not the main cause of dust storms. Therefore, option C is the correct statement regarding dust storms.
