what is air current explain in simple language
Answers
Answer:
air current - air moving (sometimes with considerable force) from an area of high pressure to an area of low pressure; "trees bent under the fierce winds"; "when there is no wind, row"; "the radioactivity was being swept upwards by the air current and out into the atmosphere"
Answer:
in simple words I can say
sir current is something that flow in rivers, lakes, and, oceans. Electric currents flow through power lines or as lightning.
Air Currents
Explanation:
Air currents flow in the atmosphere, the layer of air surrounding the Earth. Water currents flow in rivers, lakes, and, oceans. Electric currents flow through power lines or as lightning.
Air Currents
Moving air is called wind. Air currents are winds that move in a riverlike flow in a certain direction. Thermal updrafts are gentle currents caused by warm air rising. Birds like eagles or California condors often ride these updrafts high into the sky. Jet streams are rapidly moving cold currents that circle the Earth high in the atmosphere.
Air currents are caused by the sun's uneven heating of the Earth. As sunlight beams down on the Earth, it warms some areas, particularly the tropics, more than others. As the Earth's surface is heated, it warms the air just above it. The warmed air expands and becomes lighter than the surrounding air. It rises, creating a warm air current. Cooler, heavier air then pushes in to replace the warm air, forming a cool air current.
Some air currents are familiar. Santa Ana winds are seasonal (fall) occurrences in southern California. These warm, dry currents blow from the Mojave Desert and the Great Basin toward the Pacific Ocean. Jet streams are familiar to mountaineers who climb Mount Everest, Earths tallest point.
The summit of Mount Everest actually pierces the jet stream, creating icy winds at the top of the world.
