Question

Describe how the motion of Earth is affected by the sun. Be sure to include the direction of any force you identify and the shape of the path that results.

Answer 1

The effect of motion of Earth by the sun is given below.

Explanation:

1. The Earth rotates once on its axis about every 24 hours. If you were to look at Earth from the North Pole, it would be spinning counterclockwise. As the Earth rotates, observers on Earth see the Sun moving across the sky from east to west with the beginning of each new day. We often say that the Sun is "rising" or "setting", but actually it is the Earth's rotation that gives us the perception of the Sun rising up or setting over the horizon. When we look at the Moon or the stars at night, they also seem to rise in the east and set in the west. Earth's rotation is also responsible for this. As Earth turns, the Moon and stars change position in our sky.

2. Tides are the regular rising and falling of Earth's surface water in response to gravitational attraction from the Moon and Sun. The Moon's gravity causes the oceans to bulge out in the direction of the Moon. In other words, the Moon's gravity is pulling upwards on Earth's water, producing a high tide.

3.The Moon's position in its monthly orbit determines how it appears from Earth. The diagram on page 725 shows how the positions of the Moon, the Sun, and Earth affect the shapes you see in the sky. ... As the Moon moves along its orbit, sunlight begins falling on the near side. You see a thin crescent shape.
