How is long - wave radiation affected on it's way back into space(from Earth's surface)

because there is no material-medium in the space. there is only vacuum or empty space

When it reaches the Earth, some is reflected back to space by clouds, some is absorbed by the atmosphere, and some is absorbed at the Earth's surface.

Hope this helps!

are you referring to matrix mathematics!

hi there!

question - how does mountainous terrain affect settlements in a region? choose all answers that are correct.

groups trade with each other regularly.

people travel from settlement to settlement.

why: since they travel to go trade or visit it may be harder to get there because of the mountainous terrain.

hope this : )
