When wind creates a sand dune, the sheltered side of the dune

The correct answer is - is more steeply sloped.

When there's winds in the deserts they carry a lot of sand particles with them, and once they start to lose speed, the sand particles start to deposit. As they deposit, they start to create a hill of sand, so called sand dune. The sand will start to accumulate, and as the sand dune grows in size, the accumulation of sand will be much bigger on the side from where the wind comes, while the other side will be partially sheltered and get less send. Because one of the sides will continue to grow, and the other one not, the side from where the wind comes will be much less steeper, while the sheltered side will become much steeper.

answer; seasons change because earth tilts on its axis; and the angle of the tilt causes the northern and southern hemisphere to trade places throughout the year;

for e2020. the answer would be some directions from the mountain range so we can find mt. whitney. to locate which direction is north, you should use a   compass. this would not only find mt. whitney, but also becuase of this long paragraph you would get points because it's not like anyone actually reads your work becuase once they read the first sentence it sounds dumb enough to not read becuase i'm not good at answering this but the answer is compass for your benefit.
