You might have experienced a drought near you and wondered why water is considered to be a renewable resource. Lets look more closely at renewable natural resources.
On the other hand nonrenewable water resources are deep aquifers or groundwater that possess a minor recharge rate on the human time-scale.
Is water renewable or nonrenewable resource. There are renewable and nonrenewable water resources. Though in science water is considered a renewable resource due to the water cycle water also has properties of a nonrenewable resource. Water is a finite resource on Earth.
Nonrenewable energies come from resources that are not replaced or are replaced only slowly. The solution is intuitive. This means that nonrenewable resources are limited in supply and cannot be used.
The renewable water resource is the average flow of rivers lakes and aquifer recharge produced from the process of precipitation. If we were constantly losing water then the speed at which water forms wouldnt be very sustainable and would then be considered a nonrenewable resource. As more and more people need access to drinking water our groundwater and surface water reserves are being used up.
A renewable resource is any natural resource that replaces itself given enough time. For example as groundwater is usually removed from an aquifer at a rate much greater than its very slow natural recharge it is a considered non-renewable resource. In order for a resource to be considered renewable the amount of the resource that is used by one person must be replaced in the life time of that user.
The quantity of water on Earth is replenished via the water cycle ie. The rate of replenishment must be equal to or faster than the rate of usage. The second are called nonrenewable natural resources.
Non-renewable resources on the other hand can be depleted and cannot be replenished. Im tempted to call it renewable however just. The first answer is basically right that if you take a bottle of salt water out of the ocean it doesnt grow back.
Water is a renewable resource. They include solar wind water biomass geothermal and hydrogenfuel cells. WHY IS WATER A RENEWABLE RESOURCE Water is a renewable resource because it evaporates out of the oceans to clouds which generate rain falling on the land.
See full answer below. The water then runs into rivers and dams where it is used and the waste is partially cleaned before it makes its route to the sea where the cycle begins again. If not it would become a non-renewable resource at that location.
The water then runs into rivers and dams where it is used and the waste is partially cleaned before it makes its route to the sea where the cycle begins again. The difference between these two types of resources is that renewable resources can naturally replenish themselves while nonrenewable resources cannot. The population is expanding at a speedy rate and this is putting enormous pressure on all our resources even the renewable ones.
Is water a renewable resource. They usually come from the ground. Examples of renewable energies include solar wind hydro geothermal and biomass.
Though in science water is considered a renewable resource due to the water cycle water also has properties of a nonrenewable resource. If we were constantly losing water then the speed at which water forms wouldnt be very sustainable and would then be considered a nonrenewable resource. Water can be considered a renewable material when carefully controlled usage and temperature treatment and release are followed.
So while water can be considered renewable given its natural life cycle in our daily life we should consider it a precious and limited resource. They are called renewable because they can grow again or never run out. Renewable energies generate from natural sources that can be replaced over a relatively short time scale.
The first are renewable natural resources. This is not only because drinking water is a tiny fraction or the water bodies on our planet but also because we need to be mindful that human activities such as industrial production agriculture waste disposal and many others are polluting our environment and water. Water used to be considered renewable until studies of underground aquifers shrinking and widespread water pollution showed humans are using and polluting water faster than it can recharge.
Renewable and nonrenewable resources are energy sources that human society uses to function on a daily basis. WHY IS WATER A RENEWABLE RESOURCE Water is a renewable resource because it evaporates out of the oceans to clouds which generate rain falling on the land. The rain cycle--powered by the energy of the sun--distributes water to the different areas of the planet.
Renewable resources also known as clean energy are simply energy sources that replenish themselves and are virtually inexhaustible. Water is a natural resource which is not only found on the surface of the earth in rivers oceans lakes and streams but also underground. However it is possible to use water in ways that render it a non-renewable resource.
Updated January 09 2018. Non renewable Answer 2. Renewable resources are both the primary alternative to and exact opposite of nonrenewable resources.
These are things that can run out or be used up. One of the main reasons that water may become a non-renewable source is the population growth. Water is a renewable resource in the sense that it replenishes itself through rain.
View this answer Water is considered both a renewable and non-renewable resource.
