Explanation:
Radiation means ‘energy that is transported from one spot to another without the need of direct contact between the two locations’, Light in each carries a different amount of energy, this is what we call electromagnetic radiation or electromagnetic waves. Gamma rays are the most energetic, and radio is the least.
<em>In order from longest to shortes wavelenghts we have:</em>
- Radio waves: they are made by various types of transmitters, given off by stars, sparks, and lightning, they have the lowest frequencies (longest wavelenghts) in the electromagnetic spectrum and are used mainly for communications.
- Microwaves: they are extremely high-frequency radio waves (Their wavelength is usually a couple of centimeters) made by various types of transmitters.
- Infra-red waves: they are just below visible red light in the electromagnetic spectrum, they're given off by hot objects.
- Visible lights is the tiny part of the electromagnetic spectrum our eyes can detect.
- Ultra-Violet: this light is given off by the Sun in large quantities. We call it "UV" for short and can also be used to kill microbes.
- X-rays: they are very high-frequency waves that carry a lot of energy. They will pass through most substances, and this makes them useful in medicine and industry to see inside things.
- Gamma rays: they are given off by stars and by some radioactive substances. They are extremely high-frequency waves (the shortest wavelength) and carry a large amount of energy. They pass through most materials.
In the image, I annexed you can see the electromagnetic spectrum with the type of radiations from the shortest to the longest wavelengths.
I hope you find this information useful and interesting! Good luck!
Answer:
i think it's metamorphic but im not completely sure
Birth rates: moderate
Death rates: low
population growth: high
D. three-quarters of earth's water is fresh water.
I would take the advancement of the refrigeration as a crucial part in the increasing of the production.
The refrigeration has been extremely important in the agriculture and the amount of production in it, because with it the agricultural products can be kept fresh for much longer periods. Because the products can be kept fresh for much longer time, that means that they can be delivered to pretty much every part of the world and not be spoiled. So the refrigeration opened up the doors for the farmers in the sense that instead producing only for the region or the country they live in, they can now produce much more for exporting, as the products will not spoil and remain fresh. That has also brought in much bigger profit for the farmers, and the production is constantly increasing because the whole market in the world is open with this technological advancement.
