Quick Answer: Why are there four main climate zones?

The world has been divided into different climate zones. We have four main zones and two of these have sub zones. The basis of this division is variations in climate, vegetation, air pressure and the average temperature.

Why do we have 4 climate zones?

Because the Earth is a sphere, the sun’s rays reach the earth’s surface in polar regions at a much more slanted angle than at equator. … So the extra energy at the Equator needs to be spread across the planet and it’s this that creates different climate zones across the world.

What are 4 climatic zones?

According to this classification system, four major climatic belts―equatorial, tropical, mid-latitude and arctic (Antarctic), which are dominated by equatorial, tropical, polar and arctic (Antarctic) air masses respectively―are differentiated in the globe.

What is the reason for different climates?

The climate of a region depends on many factors including the amount of sunlight it receives, its height above sea level, the shape of the land, and how close it is to oceans. Since the equator receives more sunlight than the poles, climate varies depending on its distance from the equator.

Why does the earth have three climate zones?

Earth has three main climate zones because of seasonal change as it revolves around the sun.

What are the main climate zones?

The Earth has three main climate zones: tropical, temperate, and polar. The climate region near the equator with warm air masses is known as tropical. In the tropical zone, the average temperature in the coldest month is 18 °C. This is warmer than the average temperature of the warmest month in the polar zone.

What do climate zones mean?

A climate zone results from the climate conditions of an area: its temperature, humidity, amount and type of precipitation, and the season. A climate zone is reflected in a region’s natural vegetation.

Why are there different temperature zones in different latitudes?

Latitude and Temperature

At higher latitudes, the Sun’s rays are less direct. The farther an area is from the equator, the lower its temperature. At the poles, the Sun’s rays are least direct. Much of the area is covered with ice and snow, which reflect a lot of sunlight.

How four major climate regions are related to the three zones of latitude?

The first three climate zones relate to latitude. Tropical climates occur near the equator, in the low latitudes. Temperate climates occur about halfway between the equator and the poles, in the middle latitudes. Polar climates occur near the poles, in the high latitudes.

What are the 4 factors that affect climate?

Although many factors combine to influence weather, the four main ones are solar radiation, the amount of which changes with Earth’s tilt, orbital distance from the sun and latitude, temperature, air pressure and the abundance of water.

Why do different areas have different climates from influences of weather and climate?

The climate of a region depends on many factors including the amount of sunlight it receives, its height above sea level, the shape of the land, and how close it is to oceans. Since the equator receives more sunlight than the poles, climate varies depending on its distance from the equator.
