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

No, the vernal equinox day refers to the day around March 21, and the vernal equinox day is the division of solar terms in China, which is divided into 24 solar terms. The date of the autumnal equinox is around September 23. The day of the vernal equinox belongs to spring in the Northern Hemisphere and autumn in the Southern Hemisphere.

The Southern Hemisphere is the opposite of the Northern Hemisphere, and it is worth being the season. For example, March is summer in the Northern Hemisphere, while March in the Southern Hemisphere is winter.

Right. Northern Hemisphere Vernal Equinox, Southern Hemisphere Autumnal Equinox.

The 24 solar terms are not international, right? It should be a masterpiece of Chinese history.

However, theoretically speaking, the spring equinox and autumn equinox are when the sun shines directly to the equator, the summer solstice is directly against the Tropic of Capricorn, and the winter solstice is directly on the Tropic of Capricorn. For China, when shooting directly at the Tropic of Cancer, it receives a lot of heat, so it is the summer solstice; When it hits the Tropic of Capricorn directly, it receives less heat, so it is called the winter solstice. But for the Southern Hemisphere, when the sun hits the Tropic of Cancer directly, it receives more heat and less when it hits the Tropic of Cancer, so the solar terms in the northern and southern hemispheres are opposite, and the seasons are opposite.

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.

The geographical phenomena of the Earth's rotation are as follows:

1. The phenomenon of day and night alternation is 24 hours a day, with day and night alternating with each other.

2. The phenomenon of time difference, where there are different longitudes on the earth, there will be different places; Longitude is every 15 degrees, and local time is one hour apart.

3. The geostrophic deflection force is generated, and objects moving horizontally on the earth will be deflected no matter which direction they move. For example, it is right-sided in the northern hemisphere and left-sided in the southern hemisphere.

The rotation of the Earth

The Earth rotates from west to east on its axis of rotation, first rotating counterclockwise from the north pole and clockwise from the south pole. The Earth's axis of rotation is angled to the ecliptic plane, perpendicular to the equatorial plane. Various theories about the rotation of the Earth are still hypotheses.

The Earth's rotation is an important form of motion of the Earth, with an average angular velocity of rotation in degrees and a linear velocity of 465 meters and seconds at the Earth's equator. It takes 23 hours and 56 minutes for the earth to rotate around the earth, and the rotation cycle increases or decreases by 3 thousandths to 4 thousandths of a second every 10 years, so it is estimated that 400 million years ago, the earth rotated in only 22 hours.

Day and night alternate

1. Cause: The earth does not shine or be transparent, and the rotation of the earth.

2. Period: 1 solar day, that is, 24 hours.

3. Meaning of morning and dusk line: the dividing line between day and night hemisphere, including morning line and dusk line. Interpretation of the morning and dusk lines:

Rotation method: follow the direction of the earth's rotation, from night to day, which is the morning line; From day to night, it is dusk. Temporal Method:

The local time on the equator is 6 o'clock, which corresponds to the morning line; It is 18 o'clock on the Red Bush Road, which corresponds to the dusk line. Azimuth method: the east side of the night hemisphere is the morning line, and the west side is the evening line; The eastern side of the day hemisphere is the dusk line, and the western side is the morning line.

The geographical phenomenon produced by the rotation of the earth is the phenomenon of early diurnal turnover (diurnal alternation) on the earth's surface; The time difference between the local time or the district time (time difference); Objects moving horizontally produce the phenomenon of deflection (geostrophic deflection force). The geographical phenomenon produced by the rotation of the earth is the phenomenon of diurnal turnover on the earth's surface (diurnal cycle); Time difference between local time and district time (time difference); Objects moving horizontally produce a deflection phenomenon (generating geostrophic deflection forces).
