Geography Homework help!!!!!!!!?

Question

ways people have made changes to the geography of the earth.

Answer 1

Seems like a lot of negative answers abound here...but the news is not all bad...here are a few of the bad and the good all mixed together.

Deforestation has created grasslands, brush-lands and deserts in previously forested areas...Dams have filled numerous valleys and created man-made lakes...strip mines have removed mountains and created huge holes...there are countless reclaimed land projects (check out Kansai Int'l Airport in Osaka, Hong Kong Disneyland and the palm tree islands near Dubai)...most of the Netherlands should be under water...several small islands in the pacific no longer exist because they were vaporized in nuclear tests...the Aral Sea is now almost the Aral Desert due to ill-advised irrigation practices...there are major canals in Panama, Suez, China and many other areas to facilitate transportation and/or irrigation...many such systems cause deserts to bloom (anyone been to SE Idaho?)...swamps have been drained (Washington DC for example)...rivers and harbors get dredged/widened/deepened and almost every river in Japan has flood-preventing dikes built all along both sides...

I could go on all night, but sufficeth to say that many changes have been made by man, but on a global scale, most of them are fairly insignificant (including "global warming" if it exists...there are sufficient arguments both ways to throw even that into doubt). Hope it helps.

Answer 2

Well, people have
Lessened the extent of forests and replaced it with agricultural areas and urban settlements.
Increased the composition of dust,carbon dioxide and other poisonous gases in the atmosphere thereby damaging the layers of the atmosphere and changing the climate, leading to a rise in sea level.
Diverted the course of many rivers and hindered their flow by building dams.
Caused the erosion of soil in hilly and other areas by removing vegetation and exposing the top soil to the elements of nature.
Threatened the survival of many plants and animals by hunting and introducing non-native species.

Answer 3

Shores of Netherlands, the entire coast of the Netherlands is manmade, we've dug lakes. The Soviet Union BLEW a huge hole in the ground and turned it into a lake with the nuclear bomb, we've pretty much dried out the Aral Sea, we've flattened mountains, we've carved canals, we've irrigated deserts, we've devestated forests, all are changes to our geography in their own way. Oh yes. we've created lakes using dams.

Answer 4

Talking of global warming: consider the impact on the big glacier melt out happening lately (I am sure you can find changing satellite images on the net) that resulted in rise of water level.....the predicted loss land, changes coastal line of many countries especially small islands. You could also include the Asian Tsunami that has moved the small islands.

Answer 5

Dams have created lakes where there used to be rivers, strip mining has removed tops of entire mountains in Appalachia, coastal development has changed wave patterns resulting in the loss of beaches, wetlands have been drained and filled to create developable land.

Answer 6

building infrastractures like road, school, hospital and etc. And also the ozone layer which will cause to green house effect and meny more

Answer 7

Digging quarries and pits, moving mountains of dirt and rock, strip mining, making canals, burning down forests and farming which creates erosion and new landscape features. etc, etc, etc

Answer 8

Farming
Dams
Mining

Answer 9

Answer 10

pollution = ozone hole

also, consider the manmade dams and lakes and mountains etc..
