Questions : In a solar or lunar eclipse, the region of the earth’s shadow is divided into

(a) Two parts

(b) Three parts

(c) Four parts

(d) Five parts

The correct answers to the above question in:

Answer: (b)

An eclipse occurs when a star (such as Sun) aligns with two celestial bodies, such as a planet and a moon. The closer body casts a shadow that intersects the more distant body. This means that “things get dark.”

The region of the shadow is divided into an umbra, where the light from the star is completely blocked, and a penumbra, where only a portion of the light is blocked.

Beyond the end of the umbra is a region called the antumbra. For an observer inside the antumbra of a solar eclipse, for example, the moon appears smaller than the sun, resulting in an annular eclipse.

b) Venus

d) Jupiter

Answer: (c)

The water cycle, also known as the hydrological cycle or H2O cycle, describes the continuous movement of water on, above, and below the surface of the Earth. Although the balance of water on Earth remains fairly constant over time, individual water molecules can come and go, in and out of the atmosphere.

The water moves from one reservoir to another, such as from river to ocean, or from the ocean to the atmosphere, by the physical processes of evaporation, condensation, precipitation, infiltration, runoff, and subsurface flow. In so doing, the water goes through different phases: liquid, solid (ice), and gas (vapor).
