What is the water that moves across earth's surface after a heavy rainfall called?
Erosion is the process of Weathering and transport of solids (Sediment, Soil, Rock_(geology) and other particles) in the natural environment or their source and deposits them elsewhere. It usually occurs due to Sediment_transport by wind, water, or ice; by down-slope Downhill_creep of soil and other material under the force of Gravity; or by living organisms, such as burrowing animals, in the case of Bioerosion.
Erosion is a natural process, but it has been increased dramatically by human Land_use, especially Industrial_agriculture, Deforestation, and Urban_sprawl. Land that is used for industrial agriculture generally experiences a significantly greater rate of erosion than that of land under natural vegetation, or land used for Sustainable_agriculture practices. This is particularly true if tillage is used, which reduces vegetation cover on the surface of the soil and disturbs both soil structure and plant roots that would otherwise hold the soil in place. However, improved land use practices can limit erosion, using techniques such as Terrace_(agriculture)-building, conservation tillage practices, and tree planting.
A certain amount of erosion is natural and, in fact, healthy for the Ecosystem. For example, Gravel continuously move downstream in watercourses. Excessive erosion, however, causes serious problems, such as receiving water Sediment, ecosystem damage and outright loss of soil.
Erosion is distinguished from Weathering, which is the process of chemical or physical breakdown of the minerals in the rocks, although the two processes may occur concurrently.
THE LONG AND SHORT of what he may be trying to say is:
The water that runs across the surface is called surface run off
What is the correct order of the policy cycle in order?
The correct order of the policy cycle is agenda setting, policy formulation, policy implementation, and policy evaluation. Agenda setting involves identifying or defining a problem. Policy formulation involves developing solutions or policy options. Policy implementation involves putting the policy into practice. Policy evaluation involves assessing the effectiveness and impact of the policy.
Why is water pollution a concern if water is continuously cycled through Earth's systems?
Water pollution is a concern because it can harm aquatic ecosystems, disrupt the balance of organisms living in the water, and adversely impact human health when contaminated water is consumed. Despite the continuous cycling of water on Earth, pollution can accumulate in water bodies faster than natural processes can break it down or filter it out, leading to long-term negative effects. Preventing water pollution is crucial to maintain the health and sustainability of water resources for both ecosystems and human use.
Why is acid rain not a major problem in Australia?
Acid rain is not a major problem in Australia due to its low levels of air pollution from industrial activities and its large distance from major sources of air pollution in Asia. Additionally, Australia's geographical features, such as prevailing wind patterns and the Southern Ocean, help dilute and disperse any pollutants that may contribute to acid rain formation before they reach the country.
When cloud droplets combine to form larger drops they fall to earth as what?
When cloud droplets combine to form larger drops, they fall to the Earth as rain.
Where does drop of rain take place?
Drops of rain take place in the atmosphere when water vapor condenses into droplets. This process forms clouds, which eventually release the droplets as precipitation when they become heavy enough.
What is water that is not being replaced by rainfall?
Water that is not being replaced by rainfall is often referred to as stagnant water. Stagnant water is standing or still water that does not flow or circulate, increasing the likelihood of becoming a breeding ground for mosquitoes and other pests. It can also become depleted in oxygen and accumulate pollutants over time.
What would you compare rain to?
Compare rain to hail, sleet, or snow because they are all examples of parcipitation meaning that the are all made from water and fall from the clouds. The only difference is that when it is a certain temperature the rain freezes and turns into hail, sleet, or snow.
Are floods the least destructive of geological hazards?
Floods are not considered the least destructive geological hazard. While they may not cause as much immediate damage as earthquakes or volcanic eruptions, they can still result in significant destruction to property, infrastructure, and ecosystems. Additionally, floods can lead to loss of life and have long-lasting social and economic impacts on communities.
Why is a rain drop shaped like a pear?
A raindrop is shaped like a teardrop or pear because of surface tension. Surface tension causes the water molecules at the surface of the drop to stick together, pulling the drop into the characteristic rounded shape as it falls due to gravity.
Where is the rain coming from and what's inside?
Rain is formed when water vapor in the atmosphere condenses into liquid droplets that accumulate until they become heavy enough to fall to the ground. These water droplets can contain various impurities and pollutants from the atmosphere, such as dust, pollen, and chemicals.
Which is an example of good flood preparedness?
One example of good flood preparedness is creating an emergency kit with essential supplies like water, food, first aid supplies, and important documents. Additionally, having a family communication plan in place and staying informed about flood warnings and evacuation routes can also help ensure readiness in case of a flood.
What are the four major types of precipitation?
The four major types of precipitation are rain, snow, sleet, and hail. Rain is liquid water droplets falling to the ground, snow is ice crystals falling to the ground, sleet is rain that freezes as it falls, and hail is ice pellets formed in strong thunderstorms.
What does water do once on the ground?
Once on the ground, water may either infiltrate into the soil, flow over the surface as runoff, evaporate into the air, or be absorbed by plants. These processes are important for replenishing groundwater, supporting plant growth, and maintaining the water cycle on Earth.
To reduce structural damage in earthquake prone areas, steps can include improving building codes to ensure structures are earthquake-resistant, retrofitting older buildings to meet current standards, conducting regular inspections and maintenance on structures, and educating communities on earthquake preparedness and response measures.
Yes, water is a polar molecule because it has a slightly negative charge on the oxygen atom and slightly positive charges on the hydrogen atoms, due to differences in electronegativity. This polarity allows water molecules to form hydrogen bonds with each other.
How does salt water form freshwater rain in clouds?
Salt water evaporates from the ocean's surface, leaving behind the salt. The water vapor rises into the atmosphere and eventually condenses to form clouds. When the clouds cool and the water droplets become too heavy to stay aloft, they fall as precipitation, which is freshwater rain since the salt is left behind during the evaporation process.
How many inches of rain does Seattle get each year?
Seattle receives an average of around 38 inches of rain per year. This contributes to its reputation for being a rainy city.
The water cycle is a natural process that operates all around the Earth, primarily in the atmosphere, oceans, rivers, and ground. It does not have a physical location where it "lives" but rather is a system that continuously circulates water in various forms like rain, evaporation, and condensation.
What physical phenomenon cause the spherical shape of raindrops?
The spherical shape of raindrops is due to surface tension, which causes water molecules to be pulled towards each other, minimizing surface area. This results in a spherical shape, as it has the smallest surface area for a given volume.
What is the size of rain gauge?
Rain gauges come in varying sizes, but a common size is around 8-12 inches (20-30 cm) in height and 4-6 inches (10-15 cm) in diameter. The actual opening where rain is collected is typically around 4-6 inches (10-15 cm) in diameter.
What is water vapor made out of?
Water vapor is composed of individual water molecules in a gaseous state. These water molecules contain two hydrogen atoms and one oxygen atom bonded together. When water evaporates, it transitions from a liquid to a gas and becomes water vapor.
Where did the heat come from to evaporate water from sea water?
The main source of heat is from the sun.
When water drops become large and heavy enough they fall to the ground as rain?
Rain occurs when water droplets in clouds combine and grow in size until they are too heavy to be suspended in the air, causing them to fall as precipitation. This process is known as coalescence and is influenced by factors such as temperature, humidity, and air currents.
Why does Arizona have little rain?
Arizona has little rain primarily due to its location in the desert region of the southwestern United States. The state is influenced by high-pressure systems that result in dry conditions and limited precipitation. Additionally, the presence of mountain ranges can block moisture from reaching certain areas, contributing to the arid climate in Arizona.
