Ans:
1. (B)
•Denser the material, higher the velocity. Hence, velocity increases as wave moves from crust to core.
•Both P and S waves provide an idea about the interior of earth. How? P waves bend as it enters the mantle. It suggests that the medium has changed (in this case: solid to molten).
•While, S waves travel only through the solid state. This characteristic helps scientists in understanding the interior of the earth.

2. (D)
•Major reef formations are observed in the Gulf of Kutch and Gulf of Mannar. Some coral reefs around small inlets in the western part of the Gulf of Khambat have also been observed.

3. (A)
•Both Loktak and Kolleru are fresh water Ramsar sites located in Manipur and Andhra Pradesh respectively. Sasthamkotta lake is a brackish-water lake in Kerala. Similarly, Chilika lake has a status of coastal Ramsar Site.

4. (A)
•The tropic of cancer passes through Gujarat, Madhya Pradesh, Chhattisgarh, Jharkhand, West Bengal, Tripura and Mizoram.
•The northern and southern parts of the state are hilly, while the central part is a fertile plain. Deciduous forests of the Eastern Highlands Forests cover roughly 44% of the state. The state animal is the van bhainsa, or wild water buffalo.
•The Rihand River, a tributary of the Ganges, drains this State

5. (B)
•Out of the eight planets, Mercury, Venus, Earth and Mars are called as inner planets as they lie between the sun and the belt of asteroids. The other four planets are called the outer planets.
