The direction of the earth's movement

The earth rotates from west to east, and the revolution direction is from west to east.

1, the direction is from west to east

The revolution direction of the earth is the same as the rotation direction, and it is also from west to east. The north pole of the earth's axis points to the sun, so the earth goes around the sun from west to east.

Due to the tidal force of various celestial bodies and the influence of external factors such as precession, nutation and earth tides, the spatial direction and rotation speed of the earth's rotation axis change. The earth is deformed during its revolution, and at the same time, the spatial orientation and rotational speed of the rotating shaft change.

2. The rotation and revolution direction of the earth changes in four seasons.

The earth revolves around the sun to produce four seasons. In the northern hemisphere, on the solstice of summer, the sun shines directly on the tropic of cancer. In the northern hemisphere, the days are long and the nights are short, and the weather is hot, resulting in summer. At the autumnal equinox, the sun shines directly on the equatorial line, and the northern and southern hemispheres are as long as day and night, and the weather is cool, forming autumn; From winter to the sun, the sun shines directly on the tropic of Capricorn, the days in the northern hemisphere are short and the nights are long, and the weather is cold, forming winter.

The orbit of the earth's revolution is different from that of the earth's rotation.

The orbit of the earth's revolution and the orbit of the earth's rotation are not in the same plane. At the vernal equinox and the autumnal equinox, these two tracks are on the same straight line; During the summer solstice and winter solstice, these two orbital planes are perpendicular to the ecliptic plane. Because of the ecliptic angle, the position of the sun on the earth at the vernal equinox and autumnal equinox is slightly deviated.

Influence of the Earth's Rotation and Revolution on the Earth

1, ecosystem

The rotation and revolution of the earth have an important influence on the earth's climate, ecosystem and human life. For example, the rotation of the earth leads to the alternation of day and night, which changes the sunshine time and intensity in different parts of the earth's surface, thus affecting the ecosystem and the rhythm of human life.

2. Climate change

Such as seasonal changes, the rise and fall of polar glaciers and the formation of tropical cyclones. Thus affecting the ecosystem and the rhythm of human life. The polar radius of the earth will also decrease slightly. This shape change causes the distance and angle between the earth and the sun to change constantly during the revolution.
