Magma that cools and crystallizes on Earth's surface forms igneous rocks. Igneous rock is classified as intrusive or extrusive, intrusive igneous rock forms below the earth's surface, extrusive forms on the earth's surface so the answer to your question is Extrusive Igneous rock.
I positive that the answer id D why because Without<span> them the Earth </span>would<span> be too cold for us, or any other living thing, to survive. Naturally occurring </span>greenhouse gases<span>, such as carbon dioxide and methane, allow solar radiation to reach the Earth's surface, while trapping radiation from the Earth on its way back out to space.
Hope I helped

Well, the cell membrane is full of a bunch of little holes. Sort of like a coffee filter.
What does a coffee filter do? Well, you put the coffee in it and run water through it. Then what?
The water is small enough to pass through the filter and bring some of the coffee with it. But the coffee grains are too big to pass through the filter. If we really wanted the coffee grains to get through the filter, we could force them through. Do you want chunks in your coffee? Eww.
Now the cell membrane is the same way, the little things (water, carbon dioxide, oxygen, sugar) are all small enough to fit through the tiny holes in the cell membrane. This is called, "Passive Transport". Because the things can passively float their way in and out of the cell.
Now some other things are too big to fit through, so to make them fit, the cell has to use energy to open itself a little bit more to let them in. This is called, "Active Transport". Because the cell needs to be active and use energy to let those things in.
<span>Now Osmosis is the transfer of water and salts (basically) throughout the cell.
Both Salt and Water are small enough to fit through the Cell Membrane using "Passive Transport".
I've posted this same response earlier, and it is my writing.</span>
Se denomina “energías renovables” a aquellas fuentes energéticas basadas en la utilización del sol, el viento, el agua o la biomasa vegetal o animal -entre otras-. Se caracterizan por no utilizar combustibles fósiles –como sucede con las energías convencionales-, sino recursos capaces de renovarse ilimitadamente.
