Environmental Science In Agricultural MCQ Question and Answer | Agriculture MCQ Question

Acid rain is a rainfall having pH of Less than 5.0.
Acid rain is caused by the release of sulfur dioxide and nitrogen oxides into the atmosphere, where they react with water, oxygen, and other chemicals to become sulfuric and nitric acid respectively. The pH of acid-impacted rain is generally below 5.0 on the pH scale.

Biosphere constitutes Part of earth and its atmosphere inhabited by living organisms.
It can also be termed the zone of life on Earth. The biosphere is virtually a closed system of matter, with minimal inputs and outputs.
The biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, cryosphere, hydrosphere and atmosphere.

Atmosphere CO₂ serves as source of carbon for plants.
Plants take up carbon dioxide from the atmosphere and convert it into food, forests and other similar ecosystems are considered to be some of the planet's most important carbon sinks.
Carbon dioxide during photosynthesis and much of this carbon dioxide is then stored in roots, permafrost, grasslands and forests. Plants and the soil then release carbon dioxide when they decay. Other organisms also release carbon dioxide as they live and die.

Least porous soil is Clay soil.
Clay is the most porous sediment but is the least permeable. Clay usually acts as an aquitard, impeding the flow of water. Gravel and sand are both porous and permeable, making them good aquifer materials. Porosity varies depending on particle size and aggregation.

The developer of the three-fold classification of environmental education is Newman (1981).
Newman (1981) proposed a three-fold classification of Environmental Education programmes that are Teaching, Research and Extension.
Environmental education is a process that allows individuals to explore environmental issues, engage in problem solving, and take action to improve the environment.

Chemical conversion processes are often employed for collection of Particulate.
A chemical conversion coating is a surface treatment applied to metals in which the metal undergoes a chemical reaction at the surface. This chemical reaction transforms the metal surface into a thin protective layer.
Chemical manufacturing process in which chemical transformation takes place, that is, the product differs chemically from the starting materials.

Colourless, odourless and non-corrosive air pollutants are Carbon Monoxide.
Carbon monoxide is a poisonous, flammable gas that is colorless, odorless, tasteless, and slightly less dense than air.
Carbon monoxide is a temporary atmospheric pollutant in some urban areas, chiefly from the exhaust of internal combustion engines but also from incomplete combustion of various other fuels.

First National Park of India is Corbett National Park
Jim Corbett National Park is a national park in India located in the Nainital district of Uttarakhand state. The first national park in India, was established in 1936 during the British Raj.
Corbett National Park comprises 520.8 km² area of hills, riverine belts, marshy depressions, grasslands and a large lake. The elevation ranges from 1,300 to 4,000 ft.

Principles of Resources Recycling may be
A. High-quality energy cannot be recycled.
B. Don't doute, disperse, or mix products that contain recylable matter resources.
C. Recycling matter always requires high-quality energy.
Recycling of farm resources reduces input costs, enables low reliance on external inputs, improves quality of products and ultimately ensures farm sustainability under climate change conditions.

Maximum oxygen comes from Phytoplankton.
50% of the oxygen in our atmosphere has been produced by phytoplankton. Like plants and trees on land, phytoplankton gives us a lot more than food.
One type of phytoplankton, Prochlorococcus, releases countless tons of oxygen into the atmosphere.
