What are problems caused by gases that are released into air as pollutants?
Acid rain mainly caused by SO2. Global Warming mainly form C02.
What causes water currents?
Surface ocean currents are mainly wind-driven and occur in all of the world's oceans. Examples of large surface currents that move across vast expanses of ocean are the Gulf Stream, the North Atlantic Current, the California Current, the Atlantic South Equatorial Current, and the Westwind Drift. Associated with surface currents are counter-surface and underlying currents. Surface ocean currents are deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere due to the Coriolis effect. The Coriolis effect holds that because the Earth is spinning, surface waters move in a clockwise direction in the Northern Hemisphere and in a counterclockwise direction in the Southern Hemisphere. The currents eventually come into contact with the continents which deflect them, creating giant oceanic current circles known as gyres. Vertical and ocean-bottom currents are mainly driven by density differences caused by changes in temperature and salinity. Originating in polar regions, cold, salty waters sink to the ocean bottom and move toward the opposite poles where they again surface. Vertical upwelling currents can also be caused by winds "blowing off" a coastline. The displaced waters are then replaced by underlying bottom waters. Currents are important to marine life as they help to move food and nutrients, making them available for photosynthesis, metabolic requirements and/or consumption.
Soil erosion is mainly caused by what?
wave action
What is heat transferred mainly by in the troposphere?
convection currents.
How is heat transferred through a radiator?
Convection, which is the transfer of heat by thermal currents in the air (or other medium)
What types of matter does convection occur?
Convection occurs mainly in the gaseous state, where heat is transferred through currents in air. Convection can also occur in liquids, however it is generally identified with gases.gas and liquid
How is earths outer core heat mainly transferred?
It is mainly transferred by convection currents. If you have a science book, you could check there too. Just read carefully. :)
What 2 processes transport Earths energy surpluses poleward from the tropics?
Wind and water. Air currents (wind) carry heat poleward. This is mainly heat transfer by convection. Water currents carry heat poleward. This is heat transfer by convection and conduction.
Currents are mainley caused by?
Surface ocean currents are mainly wind-driven and occur in all of the world's oceans. Examples of large surface currents that move across vast expanses of ocean are the Gulf Stream, the North Atlantic Current, the California Current, the Atlantic South Equatorial Current, and the Westwind Drift. --- Vertical and ocean-bottom currents are mainly driven by density differences caused by changes in temperature and salinity.
What is the relationship of convection currents and rain?
Convection currents are part of the water cycle. The sun heats up the ground and causes moisture from the ground to evaporate. The moisture rises and condenses to form clouds which can become very large in size. The clouds become very dense and precipitation takes place e.g. rain. The cycle can then take place again. This occurs mainly in very hot countries.
How convection is used?
Convection is just heat transfer by creating currents to move the heat around from a source to where the heat is wanted. This occurs for instance in an oven during cooking, or from radiators in a central heating system.air: The invisible gaseous substance surrounding the earth, a mixture mainly of oxygen and nitrogenMore »

Why can someone standing next to me feel heat coming from my body?
Probably mainly through radiation of infrared light. Some transfer through conduction or convection is also possible.
Does convection happen when hot water displaces cold water?
Sort of. In truth, convection happens mainly over a heat source, and not just with water (one example is the Earth's inner mantle). The hotter material closer to the source rises (because the molecules have more kinetic energy), but loses that energy once it reaches the surface, sinking back down as it gets slightly more cool and dense. Since this is a continuous cycle, convection "currents" often occur. Check out this link for a picture of convection currents: http://upload.wikimedia.org/wikipedia/commons/f/f5/ConvectionCells.svg
