What are solar radiations?

Solar radiation can be described as electromagnetic waves coming from the sun and comes in three major types: visible light, infrared light, and ultraviolet light.

The electromagnetic spectrum has seven different types of light, listed from lowest frequency to highest: radio waves, microwaves, IR light, visible light, UV light, X-rays, and gamma rays. Solar radiation is light from the sun that can be categorized by its frequency and wavelength.

Solar irradiance can be described as the power per unit area received from the Sun in the form of radiation in the wavelength range and is measured in watts per square meter.

This may be measured in space or at the surface of the earth after atmospheric absorption and scattering. The forests have plants and trees which absorb the most solar radiation.

Dr. Grey performed an experiment to test how temperature affects activity levels in mice. She put one group of mice in a cold environment and another group of mice in a hot environment. Everything else about the two environments was the same, including the type and amount of food and water. She allowed the experiment to last for a few generations of mice and tested the activity levels of the different groups. There was no change in the activity levels of the mice, but she noticed that the mice in the cold environment had much darker, thicker fur than the mice in the hot environment. What scientific question could she ask based on her results? A. Does temperature have an effect on fur color and thickness in mice? B. Do the mice in the cold environment run faster than the mice in the hot environment? C. Which group of mice is the most attractive? D. Does food type have an effect on fur color and thickness in mice?

What would happen if the sand dunes in an area were destroyed?

Answers

Answer:

Then everything around the sand dunes are destroyed. It's like a domino effect.

Explanation:

Sand dunes are very helpful in coastal management. Destruction or destabilization of sand dunes will make us it hard to survive from storms and destruction of some vegetation also.

What is sand dunes?

Shorelines and desert landscapes frequently have sand dunes. Highly specialized plants and animals, especially rare and endangered species, find habitat on dunes.

Sand dunes offer essential ecological habitat as well as natural coastal defense against storm surge and strong waves, preventing or minimizing coastal flooding and structural damage. They serve as sand storage sites as well, delivering sand to beaches that have degraded.

Human activity, both purposeful and unintentional, endangers dunes Significant dune protection projects are run by nations like the United States, Australia, Canada, New Zealand, the United Kingdom, and the Netherlands.
