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?
What happens to convection currents when liquid or gas is no longer heated? Which one of the following best describes sublimation? A)The movement of gaseous particles so that they fill the space that they occupy B)A solid forming a vapour on heating and reforming as a solid on colling...
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.
阅读理解 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 (可见度). This wind is usually caused by convection currents (对流), which are created by ...

The convective zone, which is the final 30 percent of the sun's radius, is dominated by convection currents that carry the energy outward to the surface. These convection currents are rising movements of hot gas next to falling movements of cool gas: It looks kind of like glitter in a sim...
Conclusions: 1. What you observed is called a convection current. What caused the convection current to begin?in others?)
Sea breezes are caused by convection currents. What is a sea breeze? Sea breezes occur on summer days because land heats up faster than the sea. Warm air rises as it is less dense than cooler air. As the warm air rises, cooler air from over the ocean moves over land to take its ...
根据第一段中的“T his windis usually cau sed by convection currents(对流), which arecre ated by intense heating of the ground..."可知,因为地面极度的热量导致了空气流,从而产生 风,风再吹动沙丘导致了沙尘暴的产生。所以D项 正确。 13.【答案】B 【解析】题目翻译:从第二段我们可以了解到目 前...
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...
