What is the term for moving water over the land and with it pollution to the ocean?

The water, or hydrologic, cycle describes the pilgrimage of water as water molecules make their way from the Earth’s surface to the atmosphere and back again, in some cases to below the surface. Earth’s water continuously moves through the atmosphere, into and out of the oceans, over the land surface, and underground.

What word means the overflowing of a river or brook or the collecting of water over places which are not normally under water?

flood–An overflow of water onto lands that are used or usable by man and not normally covered by water. flood, 100-year–A 100-year flood does not refer to a flood that occurs once every 100 years, but to a flood level with a 1 percent chance of being equaled or exceeded in any given year.

What do you call water flow?

Streamflow, or channel runoff, is the flow of water in streams, rivers, and other channels, and is a major element of the water cycle. The discharge of water flowing in a channel is measured using stream gauges or can be estimated by the Manning equation. The record of flow over time is called a hydrograph.

Why should we boil water before drinking for Class 2?

Boiling. If you don’t have safe bottled water, you should boil your water to make it safe to drink. Boiling is the surest method to kill disease-causing organisms, including viruses, bacteria, and parasites.

Can we drink freshwater?

Fresh water is not always potable water, that is, water safe to drink by humans. Much of the earth’s fresh water (on the surface and groundwater) is to a substantial degree unsuitable for human consumption without some treatment.

What is the term used when water is added back underground?

Recharge occurs when water seeps into the ground to replenish underground aquifers. Although some recharge happens incidentally—water flowing into the ground from rivers, unlined canals, or excess irrigation—intentional recharge can restore groundwater levels and store water for later use.

What is the difference between point and nonpoint pollution?

Point-source pollution is easy to identify. As the name suggests, it comes from a single place. Nonpoint-source pollution is harder to identify and harder to address. It is pollution that comes from many places, all at once.

What is the term used to describe an overflow or large accumulation of water that submerges the land that is not normally covered by water?

Flood, flash flood, deluge, freshet, inundation refer to the overflowing of normally dry areas, often after heavy rains. Flood is usually applied to the overflow of a great body of water, as, for example, a river, although it may refer to any water that overflows an area: a flood along the river; a flood in a basement.

What is the term used for a place where water flows out of the ground?

An aquifer is an underground layer of rock that is saturated with groundwater. One of the biggest aquifers in the world is the Ogallala aquifer in the American Midwest. Water that flows out of the ground where an aquifer meets the surface is called a spring.
