Million Years Ago Gulf Of Mexico
1,898 wordsIntroduction What is the oceans role in climate? The oceans play a vital and pivotal role in the distribution of life sustaining water throughout our planet. 86 % of the evaporation that occurs on earth is over the oceans. The oceans are the planets largest reservoir of water transferring huge amounts of water around the hydrological cycle. In fact the oceans dominate the hydrological cycle, for they contain 97 % of the global water inventory. The hydrological cycle can be disrupted by changes i...

Ice Sheet Good Example
1,201 words... main types of moraine that can be recognised, lateral moraine, medial moraine, terminal or end moraine, recessional moraines and push moraines. Lateral moraine forms along the edges of the glacier. It is made up of material from the valley walls which is broken up by frost shattering and falls onto the ice surface. It is then carried along the sides of the glacier. When the ice melts it forms a ridge or embankment of material along the valley side. This can clearly be seen in figure 15. 1, w...

Southern Hemisphere Columbia River

The Salmonids can not in any manner cross the warm tropical region and therefore did not colonize what suitable regions there are for them in the southern hemisphere. But with man's help they can, and rainbow trout are now found on every continent except Antarctica. Let us assume that an original Salmonid ancestor originated in a cold fresh water lake or...

Ice Sheets Ice Ages
1,249 wordsContinental Glaciers The Action of Ice on Land As glaciers become extremely large, they eventually reach the lowlands, which is essentially more gentle terrain. As these huge glaciers reach the lowlands, they travel much more slowly, because they no longer have the steep mountain sides to push the ice down faster. Once on the lowlands, the glacier spreads out for they are no longer restricted by valleys, and become known as Ice Sheets. As long more snow falls than ice melts, Ice Sheets will cont...

Carbon Dioxide Nitrous Oxide
1,288 wordsThe Clouded Atmosphere Clouded Atmosphere The concentration of the atmospheres main greenhouse gases specifically, carbon dioxide, methane, nitrous oxide, and water vapor, have increased significantly during the industrial age. These high concentrations are predicted to continue in the atmosphere for thousands of years to come. This increase in specially carbon dioxide, increases the infrared energy taken in by the atmosphere, and warming the earths surface. The Global mean temperature over the ...

Coastal Plain Hudson River
1,539 wordsNew York s Geology The bedrock of the earth is made up of rock bodies that vary in size, shape, orientation, composition, color, and texture. These rocks makeup the bedrock, which is present everywhere. If one were to study a map of the bedrock from a vehicle point of view, they would find that patterns are made by eroded edges and surfaces of rock bodies that crop out of the state. Most rock bodies are originally tubular and horizontal. Deformations of these rock bodies occur over many years du...
