12.56 because you multiply the radius by 2 then multiply that by 3.14
Answer: 120 - 240 kilometers per hour
Explanation:
Jet streams are narrow, fast flowing, air currents that are in the atmospheres of certain planets, which includes the Earth. Jet streams are air currents that are placed very high above the Earth and form where there are big differences in temperature in the atmosphere.
The jet stream has winds that blow up to 120 - 240 kilometers per hour which can greatly influence the impact of weather patterns over a continent.
The lithosphere, which is the rigid outermost shell of a planet (the crust and upper mantle), is broken up into tectonic plates. The Earth's lithosphere is composed of seven or eight major plates (depending on how they are defined) and many minor plates. Where the plates meet, their relative motion determines the type of boundary: convergent, divergent, or transform. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along these plate boundaries. The relative movement of the plates typically ranges from zero to 100 mm annually.[2]
Tectonic plates are composed of oceanic lithosphere and thicker continental lithosphere, each topped by its own kind of crust. Along convergent boundaries, subduction carries plates into the mantle; the material lost is roughly balanced by the formation of new (oceanic) crust along divergent margins by seafloor spreading. In this way, the total surface of the lithosphere remains the same. This prediction of plate tectonics is also referred to as the conveyor belt principle. Earlier theories, since disproven, proposed gradual shrinking (contraction) or gradual expansion of the globe.[3]
Tectonic plates are able to move because the Earth's lithosphere has greater strength than the underlying asthenosphere. Lateral density variations in the mantle result in convection. Plate movement is thought to be driven by a combination of the motion of the seafloor away from the spreading ridge (due to variations in topography and density of the crust, which result in differences in gravitational forces) and drag, with downward suction, at the subduction zones. Another explanation lies in the different forces generated by tidal forces of the Sun and Moon. The relative importance of each of these factors and their relationship to each other is unclear, and still the subject of much debate.
Local winds are caused by either topographic effects or by variations in surface composition. By the term surface composition, it actually means the land and water that is present locally. Local winds are not found everywhere but in certain specific areas around the globe. I hope the answer comes to your help.
I believe it's globular and open are the main types.
