This photograph shows a mountainside with exposed coal beds interlayered with sandstone and shale. The coal was formed as debris from the landscape and was gradually buried 4 to 10 km deep over a very long period of time. Under the right conditions, what type of initial landscape could these coal beds have formed from?

Based on what you know about the location of the earth in relation to the sun, why is this called the goldilocks zone in other galaxies? a. it's a region that exhibits a weak gravitational pull, thus maintaining a safe distance from the sun. b. it's an area that doesn't experience any major weather events that could cause mass extinctions. c. it's an area that's an optimal distance from the sun for potentially supporting life. d. it's a region that's unaffected by asteroid or meteor impacts.
