Explanation:
your question is not completed , perhaps the question is similar to this solution, you can use it .
The balanced equation is
3 Fe (s) + 4 H2O (l) -----> Fe3O4 (s) + 4 H2 (g)
Explanation: In order to balance an equation we must ensure that the number of atoms of each species on right side of the arrow must be equal to the number of atoms of each species on left side of the arrow.
Answer:
o Surface Type- Because the atmosphere is heated by the Earth's surface, the surface type plays an important role in the surface air temperature. o Elevation and Aspect- Higher altitude generally has colder temps b/c the air is less dense and there are fewer molecules to absorb incoming solar radiation.
The Earth's surface is actually what heats the air above it.
Explanation:
The energy from the sun is "short-wave", and as such air is transparent to it. The sunlight goes right through the air without heating it at all. This "short-wave" radiation is absorbed by the Earth which then heats up. The heated Earth then emits it's own radiation but it is in the infrared part of the spectrum or "long-wave" radiation. This heat is what warms the atmosphere.
