What happens in convection? What causes surface currents on the ocean? What is the study of plate tectonics called? What is plate tectonic theory? What is seafloor spreading? What are the major tectonic plates? What is tectonic geomorphology?
根据第一段中的 This wind is usuallycaused by convection currents , which are created by intenseheating of the ground..可知,是因为地面极度的热量导致气流的产生,从而产生风,强风能移动整个沙丘而形成沙尘暴。42.B[提示:推理判断题。根据第二段中提到的森林砍伐、过度农耕和对水资源的过度使用,这些人类的...
Conclusions: 1. What you observed is called a convection current. What caused the convection current to begin?in others?)
Convection currents are evident in the sun. The granules seen in the sun's photosphere are the tops of convection cells. In the case of the sun and otherstars, the fluid is plasma rather than a liquid orgas.
A sandstorm, known as a dust storm, is exactly what it sounds like: a very strong windstorm, especially in the desert, that carries clouds of sand or dust, and greatly reduces visibility. This wind is usually caused by convection currents (对流), which are created by intense heating of th...
A very strong windstorm especially in the desert carries clouds of sand or dust that greatly reduces visibility. This wind is usually caused by convection currents (对流气流), which are created by intense heating of the ground, and is usually strong enough to move entire sand dunes. Air is ...
What happens when air currents rise inside a cloud? What two things cause regional wind patterns? Why does hot air rise? What determines the direction of heat flow? How does wind speed influence the Coriolis force? What is the primary reason why convection occurs in the atmosphere?
What Are Tectonic Plates: Even though our day to day life seems to occur on solid Earth, the Earth's crust is actually broken up into large sections called tectonic plates. These plates move based on convection currents of magma in the mantel. ...
convective zone - where convection currents carry energy toward the surface However, the interior may vary with respect to the location of the layers. Stars like the Sun and those less massive than the sun have the layers in the order described above. Stars that are several times more massive...
Heat waves form when high pressure airsettleshigh in the air and causes hot air tosink down. The hot air sinking creates a bubble that acts like asealandtrapsheat near the ground. This seal keeps out convectioncurrentsthat form clouds and eventually rain clouds, both of which would help the...
