A nonrenewable resource<span> is a </span>resource<span> of economic value that cannot be readily replaced by natural means on a level equal to its consumption. Most fossil fuels, such as oil, natural gas and coal are considered </span>nonrenewable resources<span> in that their use is not sustainable because their formation takes billions of years.</span>
Tropical places are hot because the humidity coming from the moisture of the plants and water are heated by the sun on the top layer of the tropical zone. The climate varies little in rain forest. There are five layers in the tropic trees so it's so thick that barely any light come through. This is also why vines grow up the trees so they can reach the sunlight to get nutrients. Also, the tropics are near the equator and that also causes the heat. The polars are cold because they barely get any sun heat to melt the snow or warm it up. The polars are melting due to certain chemicals and gasses in the atmosphere. also known as global warming. Hope that was helpful!

Answer:
I know the answer with is radio waves, but I'm not sure what out of your selection it could be ill add some things I know from my class in the explanation that hopefully help you or another brainly wiss!
Explanation:
Are radio waves completely different physical objects than gamma-rays? They are produced in different processes and are detected in different ways, but they are not fundamentally different. Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation. Electromagnetic radiation can be described in terms of a stream of mass-less particles, called photons, each traveling at light speed.
Denudation was an important geological phenomenon in the Precambrian and Paleozoic ages in the Horn of Africa.
<h3>
What were the Precambrian and paleozoic epochs like?</h3>
The Precambrian (or Pre-Cambrian, or Cryptozoic) period of Earth's history before the present Phanerozoic Eon. The Precambrian is called after the Precambrian epoch, which preceded the Cambrian. The Precambrian period encompasses 88 percent of Earth's geologic history.
PALEOZOIC
The Paleozoic (or Palaeozoic) Era is the first of the Phanerozoic Eon's three geologic periods. The Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian epochs span 541 to 251.902 million years ago.
Thus, a major geological process of that era was denudation in the horn of Africa.
