Glaciers sculpt the mountains on the surface of the Earth like great rivers and valleys of ice. They flow incessantly and landscape in many places in the Earth today are shaped by them. When the fallen snow is compressed and thickens into ice, it forms glaciers that have erosive characteristics. When snow remains in a location long enough to form ice, glaciers are formed. The most unique characteristic of the glaciers is their ability to move under its own weight.
The snow and ice gets melted and gets deposited in the water bodies. This might also cause floods. Blizzard also erodes the soil. The pressure and the temperature of the area where blizzards occur decreases. Due to excessive accumulation of snow, people
They extent of landslide also varies whereby some landslide only affects a very small area or hill slope while others cause greater impact at much larger areas. The water content, volume of material and gradient of the slope are some of the factors that affects the distance travelled by landslide material. The landslide material can travel from a few centimetres to many kilometres depending on the factors mentioned above. While landslides are usually associated with rock, debris and earth, avalanche, on the other hand is the sudden and fast flow of snow down a sloping surface. Avalanches are usually caused by mechanical failure when the force on the snow exceed its strength and causes the snow to loosen and gradually slide down a slope.
NOTES: What type of climate zones exist in canada? How do these varying climates lead to extreme weather? • Canada’s climate is very diverse as is its landscape. • Canada’s daytime summer temperatures can rise to about 35°C and higher. • Summers can be hot and dry on the prairies (Manitoba, Saskatchewan, British Columbia, and Alberta), humid in central Canada (Ontario and Quebec), milder on the coasts (New Brunswick, Prince Edward Island, Newfoundland and Labrador, and Nova Scotia), and the arctic part of Canada is basically cold all-year round as it is.
North Korea has mountains all over the country and small plains occasionally. The area covered in mountains eventually become easily influenced by the precipitation seasons and wind hazards during the winter. The terrain has eroded mountains, which is due to the winds picking up moist air. The moist air not only erodes the mountains, but also leads way into the wet summers and dry winters. Since the terrain consists of 80% mountains, the areas left over for the people to inhabit are valleys, plains, and forested areas.
Climate change is having an extreme impact on this issue and it can determine our future. The water cycle’s process depends on the weather and since it is constantly changing dramatically there is a risk of radical droughts and drastic rain. When water evaporates from the land and sea, it usually enters back into Earth as rain or snow however, due to temperatures increasing there is additional evaporation occurring which means we are receiving less water from the atmosphere. Droughts can not only cause drinking water to be scarce but it can also kill crops and farm animals as well as turn fertile land to desert (Woodward, 2008). In addition, rising temperatures has allowed air to store more water vapor which can lead to intense rain storms.
CLIMATIC FACTORS AFFECTING PLANT GROWTH The climatic factors include rainfall and water, light, temperature, relative humidity, air, and wind. They are a biotic components, including topography and soil, of the environmental factors that influence plant growth and development. • Rainfall and Water Rainfall is the most common form of precipitation. It is the falling of water in droplets on the surface of the Earth from clouds. Other forms of precipitation are freezing rain, sleet or ice pellets, snowfall, and hail.
It is known that the outcome of global climate change on hydrologic systems, especially snow and glacier melt, can modify the timing and amount of runoff in mountainous watersheds. Therefore, accurate stream flow simulation and forecast is of great importance to water resources management and planning (Abudu et al. 2010) and can provide a firm basis for forecasts of water resources availability while minimizing the risk and loss from floods caused by rapid snow and glacier melt and also support to feasibility study of hydropower potential. The physics of melting of snow and transformation of melt water into runoff are very important aspect of snow hydrology. The sun is the ultimate source of energy responsible for the melting of the snow pack.
Glaciation is believed to be a result of plate tectonics and is often related to continental drift. When continents are separated by tectonic movements, it often leads to blockage of ocean currents and therefore a gradual cause which is cooling climate that in turn leads to sea level decline and increase in ice coverage. In late Ordovician, the southern part of supercontinent Gondwana covering the South Pole led to formation of ice cap. As ice cap expands, more water will be locked on land which in turns drives a gradual change of decline of sea level. This causes a massive impact to marine lives where their habitable spaces decline leading to extinction of species.
