What are the main relief features on the Earth?

What are the main relief features on the Earth?

THE LITHOSPHERE AND ASTHENOSPHERE The major relief features of the Earth—its continents and ocean basins—were created by the movements of plates on the surface of the Earth.

What are the types of relief features?

I. First order relief – refers to the coarsest level of landforms, including continental platforms and ocean basins. 2. 3. Third order relief – most detailed order of relief includes things like mountains, cliffs, valleys, hills, and other small scale landforms.

What is ocean floor relief?

The Oceanic relief features are in the form of mountains, basins, plateaus, ridges, canyons and trenches beneath the ocean water. These forms are called Submarine Relief.

What is the effect of relief?

In mountain ecosystem: Environment. The relief of mountains affects climate because they stand in the path of wind systems and force air to rise over them. As the air rises it cools, leading to higher precipitation on windward mountain slopes (orographic precipitation); as it descends leeward slopes it becomes warmer…

How does relief affect our climate?

The higher up you are, the colder and drier it will be. When air rises it expands due to low air pressure which causes it to cool. Relief. As air is forced to rise over a piece of land (e.g., a mountain) the temperature decreases and condensation increases.

What does climate have to do with relief?

Relief can influence the amount of precipitation an area receives. When air is forced to rise over a mountain range, it cools and the moisture within it condenses. Clouds form and produce rain. This type of rainfall is called orographic rainfall or relief rainfall.

What factors affect the temperature of a place?

The temperature of air at every place is influenced by :

  • The latitude of the place.
  • The altitude of the place.
  • Distance from the sea.
  • The air- mass circulation.
  • The presence of warm and cold ocean currents.
  • Local aspects.

What are the two most important factors in temperature?

The two most important factors in the climate of an area are temperature and precipitation. The yearly average temperature of the area is obviously important, but the yearly range in temperature is also important. Some areas have a much larger range between highest and lowest temperature than other areas.

Which does not affect the temperature of a place?


Why are coastal areas more stable climates?

Air that is in contact with the ocean will be much cooler from energy transfer between water and air, while air that sits above land will heat up much more quickly. Therefore, coastal climates are much more temperate because a body of water is nearby to regulate the temperature and keep it more constant.

Why is fall so cloudy?

Now in seasons like spring, summer, and fall, there’s more warm air at the surface of the earth. Warm air rises, and as it rises, it cools. This makes the big, puffy white clouds we see that tend to let in more sunshine. But until we get warmer air that’s here to stay, expect more gloomy, grey days.

Why is it colder on clear nights?

At night cloud cover has the opposite effect. If skies are clear, heat emitted from the earth’s surface freely escapes into space, resulting in colder temperatures. As a result, temperatures decrease more slowly than if the skies were clear.

Are cloudy days colder?

On cloudy days, clouds reflect the sun’s light into space, keeping much of the energy away from the surface and leading to cooler temperatures.

Can Cloudy be hot?

A cloudy night is warmer than a clear night, due to the fact that the sun heats up the land during the day time, at night all the heat goes away into the atmosphere… But when it is cloudy, the clouds insulate the warmth, causing it to be warmer. Cloudy nights are very hot.

Why is winter more cloudy?

The supercooling of water in the upper atmosphere is aided by the lower number of hours of daylight. This results in more cloud formation. All water within clouds is frozen anyway. The cooler temperatures below the cloud prevent thawing at a fast rate therefore you get more cloud formation.

Why is a cloudy night warmer than a night when the sky is clear?

Notes: Cloudy nights are warmer compared to clear cloudless nights, because clouds Reflect back the heat given off by earth. If skies are clear, heat emitted from the earth\’s surface freely escapes into space, resulting in colder temperatures.
