Tectonic plates move due to a combination ofmantle convection,ridge push,slab pull, andtrench suction.The Earth's outer layer, called thelithosphere, is broken into large, rigid plates that float on the semi-fluid layer beneath, known as theasthenosphere. This movement is complex and results fr...
Earthquakes occur when the plates that make up the Earth's crust move around. These plates, called tectonic plates, can push against each other. Earthquakes are most common along fault lines, which are fractures that allow the plates to move. Earthquakes occur when two plates suddenly slip past...

和首字母,动词cause:引起;导致,根据主谓的一致性,疑问词what在句中充当主语,谓语动词要用一般现在时的第三人称单数形式causes,故答案为causes。 6、答案:other 解析:结合句意(当两个板块互相滑动时,地震发生了。)和首字母,固定词组each other:相互,故答案为other。 7、答案:down 解析:结...
All the earth's plates are constantly in motion, although they move very slowly, maybe an inch a year. Theypush each other, trying to slip under or over each other, or to slide past one another. Earthquakes often happenwhen two plates come together. Along the plates where the plates meet...
