A biome is a large community of plants and animals that is in a area with a distinct region. There are 5 major types of biomes worldwide. These are aquatic, desert, forest, grassland, and tundra. Hope this answers the question. Have a nice day.
Place mercury in the reactor. After a large amount of work, only a tiny portion of gold is created.
Decontaminate the resulting gold. This is harder than it sounds because you can't separate out non-radioactive gold from radioactive gold using purely chemical methods.
It should be obvious from this process that it currently costs much more money to create non-radioactive gold than you could ever earn by selling the gold. Creating gold from other elements is currently an expensive laboratory experiment and not a viable commercial activity. Perhaps technology will improve enough in the future to make creation of gold in nuclear reactors a profitable economic enterprise.
Alright.
So the picture is a little hard to see, so bare with me.
Evaporation is where the water is coming out of the ocean up into the air.
I think that is rain happening above the mountain? If so, that is precipitation.
The little river thing coming out of the mountain is runoff.
I cant really see much else on the picture though, so you might need someone else to help you there.
Nitrogen,<span>The atmosphere is composed of ~78% nitrogen and ~21% oxygen, with small amounts of other gases. The bulk composition of the earth by weight is mostly, iron, oxygen, silicon and magnesium, in that order, with all the other elements making up only about 5% of the earth's weight.</span>
