What causes Floods? Other factors which may contribute to flooding include: 1  volume, spatial distribution, intensity and duration of rainfall over a catchment; 2  the capacity of the watercourse or stream network to convey runoff; 3  catchment and weather conditions prior to a rainfall event; 4  ground cover; 5  topography; and. 6  tidal influences.

Upwelling And Its Coastal Effects Upwelling, and in particular coastal upwelling, is an oceanographic phenomenon that removes the warm (and sun heated) water at the surface away from land, and replaces it with cooler water from the depths of the ocean. The cause of this is from wind driven currents and a resulting process called Ekman transport.

- They move water and heat around the globe, and help determine the chemical make-up of the water column. Currents also are a major factor in ocean ecosystems. Two types of current motion, upwelling and downwelling, strongly influence the distribution and abundance of marine life.Upwelling.tudy the graphics and photographs illustrating upwelling and downwelling, then answer the questions about each process. Maps of the world’s major surface and deep currents are included as resources to help you understand where and how upwelling and downwelling occur.

- Source Information. Weathering causes the disintegration of rock near the surface of the earth. Plant and animal life, atmosphere and water are the major causes of weathering. Weathering breaks down and loosens the surface minerals of rock so they can be transported away by agents of erosion such as water, wind and ice.There are two types of weathering: mechanical and chemical.

Thermohaline circulation This process is known as “upwelling.”. Upwelling occurs when winds blowing across the ocean surface push water away from an area and subsurface water rises up to replace the diverging surface water. Upwelling occurs in the open ocean and along coastlines.

- As surface waters are pushed offshore, water is drawn from below to replace them. The upward movement of this deep, colder water is called upwelling. (Figure 2). Satellite image of the temperature of the ocean surface from the spring of 2000.

Currents and Climates The winds cause upwelling when they blow away the warm surface water and cold water rises to replace it.   . Upwelling brings up tiny ocean organisms, minerals, and other nutrients from the deeper layers of the water.

- 2 3. Causative Agents There are two major categories of bloat, frothy bloat and free-gas bloat. 3.1. Frothy bloat-This type of bloat can be brought about by overeating lush, damp feeds such as wet, green pasture with a high proportion of legumes cause excessive gas bubbles in the rumen.

- For example, winds favorable to upwelling tend to be somewhat weaker and more seasonal in the Pacific Northwest than further to the south. Nonetheless, they draw up a rich pool of nutrients that is enhanced by the presence of several deep water canyons nearshore. The resulting food web diversity is spectacular.

- 1 BIOLOGICAL GROWTH AND THE COOLING WATER SYSTEM Uncontrollable biological growth causes fouling, loss of heat exchange capacity, equipment failure and energy wastage. Therefore, it is important that we understand the different types of microbiological growths found in cooling water and how they can be controlled.

- The rising of hot rock from the mantle to Earth’s surface is called upwelling. This process adds new material to tectonic plates. In a June 2013 study in Nature, Conrad and other researchers found massive, extra-hot regions of mantle beneath Africa and the central Pacific Ocean.

Upwelling This may result in coastal upwelling. Upwelling is an oceanographic phenomenon that involves wind-driven motion of dense, cooler, and usually nutrient-rich water towards the ocean surface, replacing the warmer, usually nutrient-depleted surface water.n the overall process of upwelling, winds blow across the sea surface at a particular direction, which causes a wind-water interaction. As a result of the wind, the water is transported a net of 90 degrees from the direction of the wind due to Coriolis forces and Ekman transport.

- The main causes of eutrophication are. 1  natural run-off of nutrients from the soil and the weathering of rocks. 2  run-off of inorganic fertiliser (containing nitrates and phosphates). 3  run-off of manure from farms (containing nitrates, phosphates and ammonia).

- Upwelling is the movement of cold, deep, often nutrient-rich water to the surface mixed layer; and downwelling is the movement of surface water to deeper depths. Downwelling occurs when surface waters converge (come together), pushing the surface water downwards.

Wind Driven Surface Currents: Upwelling and Downwelling Background Coastal upwelling occurs where Ekman transport moves surface waters away from the coast; surface waters are replaced by water that wells up from below. Where Ekman transport moves surface waters toward the coast, the water piles up and sinks in the process known as downwelling.This example is from the Northern Hemisphere. Where Ekman transport moves surface waters toward the coast, the water piles up and sinks in the process known as coastal downwelling.here Ekman transport moves surface waters toward the coast, the water piles up and sinks in the process known as downwelling.

- The effectiveness of upwelling and its ability to support abundant sea life is greatly dependent upon the depth of the thermocline. The thermocline is the transition layer between the mixed layer at the surface and the deep water layer.

What is the importance of upwelling? Best Answer: Upwellings play an important role in the global energy balance of the ocean and of the Earth. In tropical regions, they allow an accumulation of heat that is later transferred to higher latitudes by major currents (Gulf Stream in the Atlantic and Kuro Shiyo in the Pacific).

What Causes Mudslides? You guessed it! A mudslide, of course! Mudslides occur when a large amount of water causes the rapid erosion of soil on a steep slope. Rapid snowmelt at the top of a mountain or a period of intense rainfall can trigger a mudslide, as the great volume of water mixes with soil and causes it to liquefy and move downhill.

Meningitis - Cause Meningitis also can be caused by other organisms, such as a fungus, and by conditions such as cancer or lupus. Meningitis also can be a complication of an injury (particularly to the skull or face), or brain surgery. How meningitis is spread. Germs that cause meningitis can be spread: During birth.
