Answer:Causes of Global warming
Explanation:
Where are the extra Green house gases coming from?
Most scientist think that human activities such as burning fossil fuels, using cars and other vehicles ,and clearing forest have increased the amount of carbon dioxide in the atmosphere. There are green house gases in our atmosphere,e.g. water vapor , carbon dioxide , methane nitro us dioxide and ozone.
They absorb heat from Sun rays and radiate in all directions, which warm's the Earth.The Earth could become too hot and this causes climate change which has a lot of effects on Earth. Earth's dry regions will become more drier and wet regions will become more wetter e.g.
The United States remained a largely agricultural nation until late in the 19th century. Unskilled workers fared poorly in the early U.S. economy, receiving as little as half the pay of skilled craftsmen, artisans, and mechanics. About 40 percent of the workers in the cities were low-wage laborers and seamstresses in clothing factories, often living in dismal circumstances. With the rise of factories, children, women, and poor immigrants were commonly employed to run machines.
The combination of the weathering and erosion of the stream bank and the cutting into the bedrock from the velocity of the stream combine to make a "stream valley".
<h3>
What is stream valley?</h3>
A stream valley is an earthen dip where water is present at its lowest point. These valleys are the result of erosion, which is the transfer of decomposed rock or soil from one location to another.
The formation of stream valley is given below-
- The typically V-shaped stream valley is changed to a U-shaped valley because the U-shape offers the flowing glacier the least amount of frictional resistance.
- Because a glacier's cross section and viscosity are substantially greater than those of a river, its route has fewer and wider bends.
