Factors affecting Climate.
The most important natural factors are..
1) Distance from the sea.
2) Ocean Currents.
The sea moderates the climate. It's called the moderating effect of water.
The water heats up slowly during the day, and cools down slowly during the night.
The land is opposite; it heats up quickly during the day and cools down quickly during the night.
1) Distance from sea.
3) Direction of prevailing wind.
4) Shape of the land.
5) Distance from Equator.
2) Ocean Currents.
Ocean currents play a major role in the Earth's climate system. The upper ten feet of the ocean holds as much heat as the entire atmosphere. Ocean currents transport and redistribute heat and salt.
3) Direction of prevailing wind
The prevailing winds affect the climate because when the wind kicks up it takes moisture into the atmosphere. It affects the amount of precipitation that a region receives, due to the fact that prevailing winds move in any direction and are unpredictable they can affect climate and change the temperature.
4) Shape of land
Climate can be affect by mountains. Mountains receive more rainfall than low lying areas because as the air forced over the higher ground it cools.
The higher the place is above sea level the colder it will be. This happens because the altitude increase, air becomes thinner and is less able to absorb and retain heat.
5) Distance from Equator
The distance from the equator affects the climate of a place. at the poles, energy from the sun reaches the earth's surface at lower angles and passes through a thinker layer of atmosphere than at the equator. this means the climate is cooler.
Ways humans can affect climate change..
Climate changes can also be cause by human activities, such as burning fossil fuels and the conversion of land for forestry and agriculture. In addition to other environmental impacts, these activities change the land surface and emit various substances to the atmosphere.
Burning fossil fuels like coal, oil and natural gas releases carbon that has been stored away for millions of years. It is this extra carbon dioxide that it causing climate change. The most basic concept is that our atmosphere is capable of absorbing carbon dioxide, but it can absorb only around half of what produce.
In general, the greenhouse effect is a good thing. Without greenhouse gasses, the temepurature on Earth would be too could to support life.
Since 1958, the amount of carbon dioxide in the atmosphere has been measured from a observatory on Mauna Loa, a volcano in Hawaii.
Today, the amount of carbon dioxide is higher than at any time in the last 650,000 years. And the average temperature is increasing faster than ever before.
The atmosphere is one important factor that controls the climate as it absorbs the heat from the sun which varies with location and seasons and interacts with the oceans and continents. Gases in the atmosphere are called greenhouse gases and they help retain the heat and although it is essential for warming the planet, too much of it can be bad. Without an atmosphere, the earth would either be scorching hot during the day or freezing cold during the night.
Moving of continents
Another big contribution to climate change is the movement of tectonic plates and continents. When earthquakes occur, they move the earth which affects the surrounding water and air and changes in precipitation, temperature, and in sea level occur. Tsunamis occur when plates move and they push the water around them and this water travels in a wave for thousands of kilometers destroying anything in its path.
It consists of water vapor which is one of the most major greenhouse gases of the earth. The water vapor is used to move the heat and it also produces precipitation and clouds. The Ocean Current transports the absorbed heat in the oceans from the equator (where sunlight is most abundant) to the poles to regulate and moderate the earth’s climate. The hydrosphere isn't only made up of water vapor, it is also made up of the oceans, lakes, river and streams around the world.
