Predicting space weather is tricky but our ability to do so has improved over the last few decades. Powerful flares can significantly affect spacecraft, satellites and ground-based technologies, and don't give us a whole lot of notice before striking. Numerous organizations — including NASA, ...
Here are some examples of modern technology that will change our ideas and will affect our lives greatly. Global positioning system (GPS) (全球定位系统) It’s a system that uses radio signals from satellites to show exact(精确地) information. It tells you where the user is on the earth ...
Satellites are now used as well, but they suffer from many of the same problems. Scientists do the best they can, using extremely long time spans, to try to figure out what the sea level is and whether or not it is rising. The general consensus seems to be that the oceans rise about...
How do satellites help meteorologists forecast the weather? How do dolphins use the Earth's magnetic field to navigate? How do immunosuppressants work? How do waves affect marine life? How is math used in oceanography? Why are shear waves used for defect detection?
A. protect ourselves and our satellites B. learn more about space weather C. prevent solar storms more accurately D. predict what will happen to the sun in the future 5. Which of the following is TRUE according to the passage? A. Each “kernel” is France in the picture. B. The w...
These storms release powerful bursts of electromagnetic(电磁的) energy that can affect us here on Earth by damaging power grids(电网) and satellites(卫星).By predicting solar storms more accurately, we can take steps to protect ourselves from them. “Whatwe need is to grasp(理解) the ...
Our science has overcome once insurmountable threats; for example, with the help of weather satellites, we can predict sudden changes in the weather and take precautions. Advanced agricultural technology can reduce the impact of drought or cold on crop yields. However, along with scientific progress...
It’s a system that uses radio signals from satellites to show exact(精确地) information. It tells you where the user is on the earth in all weather conditions. It’s made up of three parts: satellites, control equipments (设备) on land and receivers. ...
