Where do convection currents take place?
Convection currents occur within: the atmosphere – wind. the hydrosphere – ocean currents.
What do convection currents do?
Convection currents transfer heat from one place to another by mass motion of a fluid such as water, air or molten rock. The heat transfer function of convection currents drives the earth’s ocean currents, atmospheric weather and geology.
What causes the global convection current between the equator and the poles?
Answer: Because the Earth is (roughly) spherical the Sun’s light is distributed over a wider area towards the poles, so has less heating effect. This effect causes the equatorial regions to be heated considerably more, in turn heating the air masses above them which rise accordingly.
How do convection currents affect the atmosphere?
The heating of the Earth’s surface and atmosphere by the sun drives convection within the atmosphere and ocean. This convection produces winds and ocean currents. The greater the pressure differences between a low-pressure area and a high-pressure area, the stronger the winds.
What would happen if convection currents stopped?
On earth, this happens in air (which causes our weather), and in ocean currents. If for some reason convection stopped, air would not circulate, and weather would stop. Air wouldn’t flow over the waters, suck up moisture and then rain it out on land. Without this rain, all plants and crops would die./span>
Which ocean has the most powerful current?
Antarctic Circumpolar Current
Which ocean is the saltiest?
What is the most powerful current in the world?
What is the most important cause of surface currents?
Wind is the most important cause of surface currents. When strong, sustained winds blow across the sea, friction drags a thin layer of water into motion. The movement of the very topmost layer of the sea pulls on the water just beneath, which then in turn starts the layer under it moving.
What is the fastest ocean current?
The Gulf Stream
Where do we find the strongest surface currents on Earth?
The strongest and most renown surface ocean currents are the Gulf Stream, that travels from the Caribbean Sea, along the East coast of North America and across the Atlantic Ocean to Europe, and the Kuroshio Current in the North Pacific Ocean off the East coast of Asia.
What is the most important factor in climate?
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.
What are the 3 main factors that affect climate?
Introduction: Climate is determined by the temperature and precipitation characteristics of a region over time. The temperature characteristics of a region are influenced by natural factors such as latitude, elevation, and the presence of ocean currents.
What are the 4 factors that determine climate?
3.1 Factors affecting climate
- distance from the sea.
- ocean currents.
- direction of prevailing winds.
- shape of the land (known as ‘relief’ or ‘topography’)
- distance from the equator.
- the El Niño phenomenon.
What factors influence Earth’s climate?
Factors Affecting Global Climate
- Atmospheric Circulation. The sun’s rays provide both light and heat to Earth, and regions that receive greater exposure warm to a greater extent.
- Ocean Currents. Earth’s rotation affects the oceans in a similar manner, setting up currents that flow within the ocean basins.
- Global Climate.
What are the 5 factors that affect climate?
LOWER is an acronym for 5 factors that affect climate.
- Latitude. It depends on how close or how far it is to the equator.
- Ocean currents. Certain ocean currents have different temperatures.
- Wind and air masses. Heated ground causes air to rise which results in lower air pressure.
What factors influence weather climate?
The factors that influence climate are:
- pressure and wind.
- ocean currents.
- mountain barriers.
- land and water distribution [how close to or far from a large body of water]
What is the relation between weather and climate?
The difference between weather and climate is a measure of time. Weather is what conditions of the atmosphere are over a short period of time, and climate is how the atmosphere “behaves” over relatively long periods of time./span>
What are the 7 factors that affect weather?
Factors that affect the weather condition: temperature, pressure, moisture content, speed and direction in which its moves.
What factors cause seasons?
The Short Answer: Earth’s tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun’s most direct rays. So, when the North Pole tilts toward the Sun, it’s summer in the Northern Hemisphere.
Where is the temperature highest?
According to the World Meteorological Organization (WMO), the highest registered air temperature on Earth was 56.7 °C (134.1 °F) in Furnace Creek Ranch, California, located in Death Valley in the United States, on 10 July 1913, but the validity of this record is challenged as possible problems with the reading have …
What are the six factors that affect weather?
Weather conditions are determined by six major factors: air temperature, air pressure, humidity of the air, amount and kind of cloud cover, amount and kind of precipitation, and speed and direction of the wind.
What’s the hottest country on earth?
