A global network of observation stations measures the round trip time of flight of ultrashort pulses of light to satellites equipped with retroreflectors.
powerful source of data for studies of the solid Earth and its ocean and atmospheric systems
The correct answer is - (1) rising expanding cooling condensation.
At first there's the evaporation of water, since the water vapor is less dense than the air it rises up and starts to expend as it goes further upwards in the atmosphere. Once it reaches the upper layers of the troposphere than the cooling process starts because the temperature is decreasing with the altitude. Because of the cooling the process of condensation will start taking place and thus the formation of clouds were the water vapor returns to liquid form and creates rain. The cycle repeats its self all the time.
A hurricane (or typhoon) is a large rotating cyclonic system born in the ocean.
Answer:
Fertilizer: The ash from the volcanoes can act as extra nutrients for plants. The chemicals in the ash can make the soil richer which is beneficial for many plants.
Tourism: Volcanoes can attract people from all over the world. This can cause people to pay in order to visit. This can be beneficial to people who like in the area, since they can make money off of the tourist
Research: Volcanoes can allow humans to better understand the earth. They can also learn the patterns of the volcano's eruptions or the seismic activity leading up to the eruption.
Entertainment: Volcanoes can be used as entertainment. For example, people go on hikes or study the environment. This can lead to discoveries also.
For cities, mountains can be both a help and hindrance. Whilst mountains can be a barrier to trade and transport, they form a natural line of protection from invasion. Therefore, many ancient cities thrived when located near mountains, with the reduced risk of attack affording them time to grow and prosper
