human activities‚ whether it be destroying natural vegetation and bush lands to clear the land for farms‚ over-irrigation of cultivated land and/or poor farming practices. Countries like Australia are beginning to see the devastation of increasing salinity levels after a relatively short period of introduced European farming methods. Nature dealt reasonably successfully with salinity levels in Australia prior to European settlement. Natural vegetation‚ including deep-rooted trees‚ ensured that salts

What role does genetics play in the variation seen in this leafhopper population? Hint: How does genetics allow for variation? When it comes to the variation seen in the leafhopper population‚ there are two traits that are determined by genetics. Those traits are the color of the leafhoppers and their size. Natural selection would

GREENHOUSE EFFECTS IntroductionThe greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases‚ and is re-radiated in all directions. Since part of this re-radiation is back towards the surface and the lower atmosphere‚ it results in an elevation of the average surface temperature above what it would be in the absence of the gases.[1][2] Solar radiation at the frequencies of visible light largely passes through the atmosphere to

runoff‚ thus a lower volume of water. Less permeable rocks will then have more surface runoff‚ thus a higher volume of water. Vegetation on land such as trees and plants also affects the volume of water‚ as vegetation intercepts rain. The upper course usually has more vegetation‚ while the lower courses have less vegetation intercepting precipitation. Sparse vegetation results in less water infiltrating the ground‚ thus there will be more surface runoff‚ resulting in a larger volume of water.

The temperate forest is an area of the world that has high levels of precipitation and humidity. They contain a wide variety of deciduous trees‚ which are trees that lose their leaves in the winter. The temperatures of the temperate forests vary based on the four seasons. It is typically hot in the summer with high temperatures of 86 degrees and cold in the winter. These areas receive large amounts of precipitation in the form of rain and snow. Eastern Asia‚ Central and Western Europe‚ and the Eastern
