Document Summary
An action that increases (enhances) or reduces (buffers) the flow. Warmer temperatures less snow and ice- more energy absorbed by land & ocean. Slope erosion- stream bedload channel erosion valley side slope angle. Climate warms = more evaporation = more clouds =whiter planet =reflection = in solar radiation at surface = should reduce some warming. Earths shape and size through surveys, math and remote sensing. Generally accepted as early as 1st century a. d. (e. g. columbus) Newton could not be a perfect sphere but close. Eratosthenes earth a sphere = 360 degrees. 7. 2 degrees divided by 360 degrees = 1/50 earths circumference. Circumference of earth =50 x 925 km = 46,250 km (pretty close) Counter clock wise rotation around its axis. Earth spins one rotation with respect to the sun every day 924 hours) Coriolis force air and water current. Ecliptic plane: the imaginary plane of earths orbit. Other planets all tend to lie near this plane.
