missed these questions on a test. Just wanting to no the right answer.
PLEASE HELP

Answer 1

1) Telescopes
2) Silicon
3) Three (it's called triangulation)
4) Longitudinal (they travel along through a medium, not just side-to-side within it)
5) Stalactites (stick 'tite' to the ceiling)
6) Over the areas where the cloud cover is lowest (which is mostly the Western part of the US)
7) it blocks out harmful Ultraviolet radiation
8) Nitrogen is 79% of our atmosphere
9) a Cumulus cloud portends rain
10) a front
11) West to East
