What are the geographical phenomena caused by the rotation of the earth?

The rotation of the EarthThe resulting geographical phenomena are: diurnal cycle.

The Earth rotates from west to east on its axis of rotation, rotating counterclockwise from the North Pole and clockwise from the South Pole. Various theories about the rotation of the Earth are still hypotheses.

Earth's rotation is an important form of motion of the Earth, and the average angular velocity of rotation.

is the linear velocity of rotation at the Earth's equator in degrees and seconds.

for 465 m sec. It takes 23 hours and 56 minutes for the Earth to rotate around and increases or decreases by 3 to 4 thousandths of a second every 10 years.

The law of rotation

Pole shift. The movement of the Earth's axis on the ground is called pole shift.

There are two main reasons for pole shift, one is the result of the deviation of the Earth's axis from the axis of inertia, with a period of about 14 months. The other is caused by the seasonal operation of the atmosphere, which has a period of one year. There are some other secondary reasons for the amplitude of the pole shift.

Generally no more than 15 meters.

As a result of the pole shift, the latitude and longitude of the Earth change.

The most important geographical phenomenon produced by the rotation of the earth is the change of day and night, the earth turns from west to east, in the morning, the sun rises from the east, with the rotation of the earth, in the evening, the sun sets from the west, not the sun turns, it is caused by the rotation of the earth.

A geographical phenomenon produced by the rotation of the Earth: the alternation of day and night.

The rotation of the EarthThe four geographical phenomena that have arisen are:

1. Day and night cycle:

The earth is a non-luminous and opaque sphere, and sunlight can only illuminate half of the globe at a time, half of the globe illuminated by sunlight is day, and half of the globe that is not illuminated by sunlight is the dividing line between night, day and night hemispheres.

circle), called the morning and dusk line.

circles). 2. Changes in local time and district time:

Each place is different, so you can only use the meridians one by one. Zone time: Since Magellan circumnavigated the globe, there has been a problem of different dates in the eastern and western hemispheres, so there are 24 time zones, the middle time zone is more special, and the West 12 zone and the East 12 zone are the same time zone.

3. The direction of the horizontal movement of the object is biased

Subject to geostrophic deflection force.

Objects moving horizontally will be biased to the right in the direction of motion in the northern hemisphere and to the left in the direction of motion in the southern hemisphere. The direction of the geostrophic deflection force is perpendicular to the direction of the object's motion. The greater the velocity, the greater the geostrophic deflection force.

Only horizontal motion along the equator is not affected by geostrophic deflection forces.

4. The effect of rotation on the shape of the earth:

The inertial centrifugal force generated by the rotation of the Earth causes the Earth to gradually expand from the poles to the equator, becoming the shape of the spheroid that is currently slightly flattened.

The 4 geographical phenomena produced by the rotation of the earth are as follows:

1. First, the rotation of the earth leads to the phenomenon of day and night alternation, as a result, the temperature changes day and night in various places, and organisms form a circadian rhythm The earth is a non-luminous and opaque sphere, and the sunlight can only illuminate half of the globe at the same moment, and the half of the earth illuminated by the sun is day, and the half of the earth that is not illuminated by the sun is the dividing line and circle between the day hemisphere and the night hemisphere of the night and night, which is called the morning and dusk line and circle.

2. The second is the change of local time and zone time, local time, each place is different, so it can only be calculated with a meridian line, zone time, since Magellan sailed around the world, there is a problem of different dates in the eastern and western hemispheres, so there are 24 time zones, the middle time zone is more special, and the west 12 zone and the east 12 zone are the same time zone.

3. The third is the direction of the horizontal movement of the object, affected by the geostrophic deflection force, the horizontally moving object, in the northern hemisphere will be biased to the right of the direction of motion, in the southern hemisphere will be biased to the left of the direction of motion, the direction of the geostrophic deflection force is perpendicular to the direction of the object's motion, the greater the velocity, the greater the geostrophic deflection force, only the horizontal motion along the equatorial direction is not affected by the geostrophic deflection force.

4. Fourth, the influence of rotation on the shape of the earth, the inertial centrifugal force generated by the rotation of the earth makes the earth gradually expand from the poles to the equator, becoming the shape of the slightly flattened spheroid.
