Why is water a renewable resource?
-
Water continuously evaporates.
-
Man can create water.
-
Use of water is minimum.
-
The above statement is incorrect.
A renewable resource is any natural resource that replaces itself given enough time. The rate of replenishment must be equal to or faster than the rate of usage. As water continuously evaporates from the Earth's surface, it collects in the atmosphere to later come back to the Earth as rain. On the Earth itself surface water replenishes groundwater, and groundwater replaces surface water. With careful management and responsible usage, water is a renewable resource.

Which of the following is renewable resource of fuel
-
trees
-
fossil fuel
-
gas
-
gasoline
Trees are renewable resource of fuel as they can be planted new and can be recreated. So renewable natural resources are Trees. Hence, option A is correct.
Advantage of use of natural gas as fuel is:
-
prevents respiratory problems
-
causes less air pollution
-
prevents over combustion
-
prevents heart dieases
Advantage of use of natural gas as fuel is that natural gas releases fewer pollutants which can decrease the pollution.
Hence option B is correct.

Excessive burning of fossil fuels is a major cause of Global Warming.
-
True
-
False
Excessive burning of fossil fuels is a major cause of "GLOBAL WARMING".
Explanation :
Carbon dioxide (CO2), which, while not the most potent greenhouse gas,
is nevertheless the main driver of the greenhouse effect. When fossil fuels - coal, oil and natural gas - are burnt they release CO2 into the atmosphere. Because of this, the layer of greenhouse gas is getting thicker, which is, in turn, making the Earth warmer. Thus the ongoing unlimited burning of fossil fuels is the cause of climate change and global warming.
What are the effects of natural resource depletion?
-
reduce the quality of safe and accessible drinking water.
-
introduces harmful toxins into waterways and the atmosphere.
-
cause soil contamination.
-
All of above.
Depletion of natural resources like water, fuel-air and soil produces competition among living organisms for the remaining portions and diminishes the quality of available resources. Some of the human activities reduce the quality of drinking water. Overuse of fossil fuels reduces their availability and also introduces harmful toxins into the water and the atmosphere. Deforestation and agricultural activities exacerbate erosion and cause soil contamination, which impairs the survival capacity of plants, and makes surrounding areas prone to flooding and environmental disasters.
Which of the following is the main component of natural gas is
-
Mehtane
-
Propane
-
Butane
-
Pentane
The main component of natural gas is methane $CH _4$ some other gases like butane ethane are also present.
Hence option A is correct.
Use of public transport system instead of private vehicles
-
Increases pollution
-
Decreases pollution
-
Does not effect pollution
-
None of the above
Use
of public transport system instead of private vehicles decreases the
pollution as many people use only one vehicle which consume less fuel.It decreases the fuel consumption and pollution.
Hence option B is correct.
Which of the following is best to be used as fuel
-
Oil
-
Wood
-
Coal
-
Natural gas
Natural gas is best to use as fuel because it produces less pollution and more efficiency.Less quantity is needed for more work.
Hence option D is correct.
Deforestation
-
Increases pollution
-
Decreases pollution
-
Does not effect pollution
-
None of the above
Deforestation
is decrease in number of trees in forest so this leads to in decrease
the photosynthesis process which in turn increases the pollution.
Hence option A is correct.
