  1. Black soil

  2. Alluvial soil

  3. Red soil

  4. Laterite soil

Show answer
Correct Option: B
Explanation:

Alluvial soils as a whole are very fertile. Mostly these soils contain an adequate proportion of potash, phosphoric acid and lime which are ideal for the growth of sugarcane, paddy, wheat and other cereal and pulse crops. Due to its high fertility, regions of alluvial soils are intensively cultivated and densely populated.

  1. Crust

  2. Earth

  3. Surface

  4. Focus

Show answer
Correct Option: D
Explanation:

An earthquake is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.

An earthquake's point of initial rupture is called its focus or hypocenter. The epicenter is the point at ground level directly above the hypocenter.

Sometimes hot molten rocks formed inside the earth are forced out through openings in the earth's surface such as the craters in volcanoes. What is the molten rock inside the earth called?
