1. 语法填空 Let's clean up the ocean together! We all know it's important to have dreams.to make the dreams(come) true is not an easy thing. A young Dutch man named Boyan enjoys(work) hard to make his dreams come true. When Boyan was 17, he went diving(潜水) in Greece. He wa...
As Earth spins in a counterclockwise direction, it shapes certain ocean currents (洋流). The direction of ocean currents, together with winds, produces different weathers around the globe. But a backward spin changes the ocean currents and winds.__▲___Western areas of the lands...
Why do surface currents move a lot of heat? Why does air pressure decrease as altitude increases? What factors affect ocean thermohaline circulation? What determines the direction of respiratory gas movement? How do ocean currents affect weather?
In the winter, for example, the air over the ocean might be warmer than the air over the land, causing the wind flow to move from the land out to the sea. But in the summer, the air over the land heats up, becoming warmer than the air over the ocean. This causes the wind ...
1?A.Nowadays, scientists pictured the circulation of ocean"s water mass as consisting of large slow-moving currents.B.Before 1965 ,the concept of scientists produced only a rough approximation of the true circulation.C.Researchers began to do research on the developed techniques and ...
The light detection and ranging buoys measure conditions such as wind speed, wave height and ocean currents to help us better understand the proposed design and construction of our Morgan and Mona projects with partner EnBW. When operational, these projects could deliver a significant volume of off...
then trash it and dispose of something really useless. But we also cant underestimate the rubbish, some of the rubbish can only be processed a little bit, the variable "waste" is "treasure". These things: toothpaste tubes, old newspapers, cardboard boxes, etc. As long as we move our han...
