key determinant of distribution of species on earth Answer - climate
key determinant of distribution of terrestrial biomes on earth Answer - temperature and precipitation
weather Answer - the state of the atmosphere, including temperature, atmospheric pressure, wind, humidity, precipitation, and cloud cover
cause of seasons Answer - The tilt of the Earth's axis
summer Answer - earth tilted toward the sun (more concentrated solar energy)
