Impact craters are rare on the surface of the earth and plentiful on the moon its because our atmosphere burns up more meteoroids before they meet the surface. Another reason is that the surface of the earth is continually active and erases the marks of crater overtime. There are also many other large craters being found in Canada, Australia and Africa.
Answer:
Explanation:
physical - soil fertility, soil drainage, slope angle, aspect, scenery, mineral potential etc.
The utilisation of land is determined by the continuous interplay of the physical factors, such as relief, soil, climatic conditions, mineral resources, etc., and the human factors like density of population and the technological and social requirements of people.
It would be access to the ocean for trading and travel.
I guess an environmental impact of migration MIGHT be that the receiving country obviously will rise in population so it'll have to expand and also use more resources to sustain the extra people. Therefore, more land is urbanized which isn't great for habitats and animals, more land will have to be farmed - loss of animal habitat - and more energy will have to be used to power homes etc.
People may live in an area thats at high risk of hurricanes (etc) for the reason that they have no choice. Or maybe, in a place like Japan where they have the best warning systems and highly developed buildings, it doesnt really matter as much to them. On the other hand, people will live near volcanoes because the soil is much more fertile due to the volcanic ash. This means they can grow more food from the same soil - maybe its a risk worth taking?
If a disaster happens, some may not come back simply because its too dangerous - on the other hand, some might only move temporarily to recover or while their home is rebuilt. Tourists may not come back because it is too dangerous but it will also attract tourists because not everyone can witness a volcano or be in an earthquake.
Lots of land is free from human influence (at the moment) simply because its probably too difficult for us to settle. For example, a desert like the Sahara in Africa is EXTREMELY dry and dangerous. People have been there but it isnt constantly under human influence. Assuming our technology improves and we keep growing in population, maybe everywhere will one day be influenced by humans in some way.
Hope this helps :) <span />
Answer:
Stratosphere
Explanation:
Stratosphere. The Stratosphere extends around 31 miles (50 km) down to anywhere from 4 to 12 miles (6 to 20 km) above the Earth's surface. This layer holds 19 percent of the atmosphere's gases but very little water vapor. In this region the temperature increases with height
