In the cool air, water vapor is more likely to condense from a gas to a liquid to form cloud droplets. Cloud droplets can grow and produce precipitation (including rain, snow, sleet, freezing rain, and hail), which is the primary mechanism for transporting water from the atmosphere back to the Earth’s surface. 78 percent of precipitation that falls back into the ocean is immediately incorporated with the water already present. The other 22 percent that fall on land masses are collected into lakes, runs off on sloped surfaces or infiltrates the surface. Some of the water that falls onto Earth’s surface is absorbed into crust of the Earth through percolation or from seepage from lakes and streams.
These low-pressure areas feature weak pressure gradients and little or no rotation. Most of these disturbances die out, but a few continue down the path to hurricane status. The tropical disturbance advances through three stages to reach hurricane status: 1.Tropical depression: wind speeds of less than 38 mph 2.Tropical storm: wind speeds of 39 to 73 mph 3.Hurricane: wind speeds greater than 74 mph In these cases, the thunderstorms in the disturbance release latent heat, which warms areas in the disturbance. This causes the air density inside the disturbance to lower, dropping the surface pressure. Wind speeds increase as cooler air rushes underneath the rising warm air.
The movements of wind also affect air temperature. When the warm air moves upward, __________ air then comes in. If there is no replacement of warm air then it will always be ____________. C. DIRECTION: Write the uses of the following weather instruments. 1.
· Condensation occurs as the vapor rises into the atmosphere, creating clouds and fog. Once clouds are formed, advection -- the movement of water in its various states -- through the atmosphere. Without advection, the cycle would screech to a halt, as the water would evaporate and precipitate (the next step) in the same place. · Precipitation occurs when the vapor that condensed comes back out of the sky as rain, snow, sleet, hail. Most of it comes back to the ground or body of water, but some of it is intercepted by plant foliage and evaporates back to the atmosphere instead of making it to the ground, in a process called "canopy interception."
In the western Pacific, there is low air pressure as warn, moist air rises, cools and condenses, forming rain clouds which give heavy convectional rainfall. This movement of air results from the Walker cell. This circulation of air is where air in the upper atmosphere moves from west to east and surface air moves from east to west, as the trade winds. It causes surface waters in the west to be pushed upwards therefore sea levels in places such as the Philippines is 60cm higher than in Panama or Colombia. Water flowing westwards is warm, 28ºC in the western Pacific whereas the water off the coast of South America is cold, 20ºC.
They changed because the molecules of hydrogen and helium were moving so fast that they eventually escaped the Earth. 14. Explain how the greenhouse effect works and how it relates to global warming. The greenhouse effect is when radiation at visible wavelengths passes freely through the atmosphere and is absorbed at the ground. The ground heats up and emits infrared radiation.
Chemosynthesis - A process by which inorganic materials are converted into food using chemical energy. 1.Hydrothermal chemicals coming from the vents contains hydrogen sulfide. 2.Microbes living around the vents take in the sulfide, oxygen, and carbon dioxide from the water. 3.Microbes get energy by breaking down the hydrogen sulfide. 4.Microbes release sulfur and water.
Then, the sum of energy a normal hurricane contains is more than what hundreds of A-bombs have. This research will discuss where that energy is from, how hurricanes transfer energy, and how hurricanes release such terrifying energy. A hurricane’s source of energy is water vapor which is evaporated from the ocean surface. According to an online article “What Causes Hurricanes”, the author states: “Water vapor is the "fuel" for the hurricanes because it releases the "latent heat of condensation" when it condenses to form clouds and rain, warming the surrounding air. This heat energy was absorbed by the water vapor when it was evaporated from the warm ocean surface, cooling the ocean in the process” (Par.
Conduction occurs in both solids and liquids when adjoining particles vibrate so that they diffuse heat to one another throughout a space, until all of the particles are the same temperature. Conduction performs a significant role in the lithosphere as this is the place conduction occurs and also as this is where the Earth loses most of its internal heat. Along the mid-ocean ridges where the temperature is significantly high, mainly along the most active and major ridges, the tectonic plates thicken as they move away from the ridges and cool. From this evidence we can see that conduction is an important process as it moves the heat from the upper mantle through the lithosphere to the Earth’s crust. Convection is another method of heat transfer.
Air pressure drops more rapidly with altitude in a column of cold air. 3. On an upper-level map, is cold air aloft generally associated with low or high pressure? What about warm air aloft? Cold air aloft is associated with a surface low-pressure system.
