Estimate the amount of water there could be in a global (planet-wide) region of subsurface permafrost on mars (do the calculations for two permafrost thicknesses, 1 and 10 km, and a concentration of ice in the permafrost of 10% by volume). compare the two results you get with the amount of water in earth’s oceans calculated in example 10.1.

answer: electrons

the amount of current in the coil

laticia draws the diagram below to show earth’s magnetic field.

answer

the arrows to the right of earth should point up.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
