Temperature judges the northern and southern hemispheres.

According to the high temperature around July, the temperature in the northern and southern hemispheres can be inferred as the northern hemisphere; On the contrary, if the temperature is high around 1 month, it can be inferred as the southern hemisphere.

Specific introduction:

The equator divides the earth into two hemispheres, the northern hemisphere is in the north and the southern hemisphere is in the south. The northern and southern hemispheres are distinguished by the deviation of the horizontal motion direction of the object. Distinguish the northern and southern hemispheres by the difference in the height of the sun at noon.

Detailed introduction:

Earth (English name: Earth; Terra (Latin) is the third planet with a distance of 0/0.50 billion kilometers from the sun, and it is also the only celestial body known to human beings that breeds and supports life.

About 29.2% of the earth's surface is land composed of continents and islands, and the remaining 70.8% is covered by water, mostly salty water bodies such as oceans and bays, but also fresh water bodies such as lakes, glaciers and rivers, especially glaciers, which together constitute the hydrosphere.

Most of the polar regions of the earth are covered with ice. The outer layer of the earth is divided into several rigid tectonic plates, which have migrated on the surface for millions of years, but still remain active inside, including a solid iron core, a liquid outer core that generates the earth's magnetic field, and a convective mantle that drives the plate structure.

The earth's atmosphere is mainly composed of nitrogen and oxygen. Tropical regions receive more solar energy than polar regions and redistribute it through atmospheric and ocean circulation. Greenhouse gases also play an important role in regulating the surface temperature.

The climate of a region depends not only on latitude, but also on altitude and proximity to the region and the ocean. Severe weather such as tropical cyclones, thunderstorms and heat waves mostly occur in vast areas and have a great impact on life.

The gravity of the earth will interact with other objects in space, especially the moon, which is the only natural satellite of the earth. It takes about 365.25 days for the earth to make a revolution around the sun. The rotation axis of the earth is inclined relative to its orbital plane, so seasons are produced on the earth. The gravitational interaction between the earth and the moon causes tides, stabilizes the direction of the earth on its axis, and gradually slows down its rotation speed.
