All in all, areas with warm temperatures will have faster chemical reactions, so, weathering in the tropics is rapid. Although the desert is a warm place, it does not have a quick weathering rate. The reason for its slow chemical weathering, is because
The riverbed and banks are smooth and there is high velocity so large particles are transported. However, when the river meets a large body of water, eg the ocean, the ocean absorbs the energy of the river so it becomes much slower. As chemical changes occur between freshwater and saltwater
They must be more cautious of distance between cars in case one needs to stop quickly. These drivers may also have to cope with frost and condensations on the windows. Both can decrease visibility and reduce driver awareness, while the summer is generally warmer and dryer. The summer roads are less wet and icy than winter roads, letting drivers to escape possible threats much quicker with less reaction time. In contrast, winter driving requires advanced reaction times, greater technical skills, and a higher level of vehicle maintenance for optimal driving conditions.
The King tried implementing several policies to increase the food supply, such as price controls on livestock and restrictions on the production of ales and other products made from the limited supply of grain. None of these policies worked, because there simply was just not enough food (32). People hoped the harvest of 1315 would be the end of it, but heavy rainfall in 1316 continued the hunger. The shortage of food became so severe that paupers were forced to eat dead bodies of cattle to survive. People from Northern France are rumored to
Millions of acres of farmland became useless and hundreds of thousands of people were forced to leave their homes and migrated to California and to other states. Owning no land, many migrant workers traveled from farm to farm to pick fruit and other crops at starvation wages (Hornbeck, pg16-18). During The Early European and American Exploration of the Great Plains, the region in which the Dust Bowl occurred was thought unsuitable for European-style agricultural endeavors were primarily cattle ranching with some cultivation, however a series of harsh winters beginning in 1886, followed by a short drought in 1890 which led to an expansion of land under cultivation (Egan pg20-22). It was an important determinant of The Great Depression because throughout the 1930’s more than a million acres of land were affected by The Dust Bowl, thousands of farmers lost their livelihood, property, and mass migration patterns began to emerge, farmers left rural American in search of work in urban areas (Haberler, pg 70-72), During The Great Depression, severe drought conditions prevailed much of The United States plains soil turned to dust and large dark clouds could be seen across the horizon in Texas. Nebraska, Oklahoma, Kansas, Colorado and New Mexico.
Since it occurred during the Great Depression, the Dust Bowl migration became significant due to the riskiness in relocation because of such high unemployment rates. So, in the context of very low internal migrations in America at this time, the Dust Bowl Migration really stands out. However, apart from the fame, the migration was misnamed because most of the people migrating weren’t victims of the dust; instead they were victims of drought and depression. Despite of the critical distance, 200,000-400,000 farmers- out of the 3 million- from Oklahoma, Texas, Arkansas, Kansas, and Missouri traveled as families to California. The push factors of their homeland- no arable land for crops, contaminated water, and no money- caused the farmers and their families to leave .Then California’s pull factors, such as harvest labor job opportunities, attracted these refugees of depression.
Also air conditioners exchange heat with atmospheric air, causing further local heating. Additionally, concrete, needed for the expansion of cities, absorb huge amounts of heat, increasing the mean surface temperatures of urban areas. Tall buildings, and often, accompanying narrow streets, hinder the circulation of air, reduce the wind speed, and thus reduce any natural cooling effects.
At constructive plate boundaries, the lava is generally basaltic and therefore has low viscosity, meaning that it flows easily and gases can escape easily. This means that these eruptions are less violent than destructive eruptions, however they do occur more frequently but are not explosive, so are effusive. A good example is the Mid Atlantic ridge, where there is constant volcanic activity below the
Black ice is well known in Alaska for forming a thin sheet of ice on the road making it extremely dangerous for drivers. Despite temperatures being below zero throughout most of the year, the summers can be quite warm for the area. Temperatures can reach up into the high seventies during the warmest months. Conversely, the temperatures in Hawaii are in the seventies regularly throughout the year, but the high humidity can make it feel much hotter than it actually is. The Trade Winds come across the east coast to help moderate the humidity and heat, making the weather more bearable.
-Areas near the sea are cooler in the summer because the sea takes a long time to heat up and so cools the land down. -The West of the UK gets warmer more than the east because of a warm ocean current coming from the South West called the North Atlantic drift. 4) PRESSURE: -Low-pressure weather systems have lots of rainfall because the air is rising and water vapour is condensing. High-pressure systems have dry weather because the air is falling. -Low pressure weather systems come from the west, so the west of the UK is wetter.
