In the following passage, some words have been deleted. Read the passage carefully and select the most appropriate option to fill in each blank.

Any (1)_______ that revolves around a planet is a satellite. Mother Earth has a natural satellite in the moon. The earth is circled by a lot of man-made or artificial satellites. In 1957, the Soviet Sputnik was the first to be (2)_______ into space. There are currently a number of artificial satellites launched into space by various nations. These satellites make it possible for us to talk on the phone, watch television, predict the weather, map the various surfaces of the earth and learn more about the world in which we live.

How does a satellite get started? It is typically launched into space by means of a rocket. After ascending into the thinner air layers above the earth, the satellite is released from the rocket. For a successful satellite launch, a rocket's speed is carefully calculated and controlled. Every object in space is pushed toward the earth's centre by gravity. The inertia of motion will propel the object into space if it has its own velocity of motion. When the orbital velocity is exactly right, these two opposing forces are balanced, causing the satellite to (3)_______ toward the earth while still hovering over its surface. A satellite is said to be in geo-stationary orbit when it completes one revolution around the earth in a 24-hour period; It doesn't change when compared to a point on the surface of the earth. These orbits are typically used by satellites for communication and weather. The camera on the weather satellites takes pictures and sends them back to Earth. These are helping aid in weather forecasting. Radio receivers and amplifiers on communication satellites can (4) _______ waves back at a frequency that is different from the one the satellite received. The beaming frequencies of satellites that are 'parked' too close to one another must not interfere with one another. Television signals can be transmitted from one location to other using broadcast satellites, and scientists can (5) _______scientific data from numerous satellites.

According to Koeppen's Scheme, which type of climate is denoted by the letter 'E' in India?

Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. Polar type.

According to Köppen's climate classification scheme, the letter 'E' denotes the polar climate type. This type of climate is characterized by very cold temperatures year-round, with no significant warming even in the summer months.

In India, the polar climate (E) is not typically found due to the country's generally warmer climate. However, the Himalayan region at high altitudes, particularly in areas above the tree line, experiences conditions that can resemble a polar climate with cold temperatures and heavy snowfall.
