their eyelashes keep sand out of their eyes
In the shade, in burrows under the sand, in caves, under water, or anywhere it's less hot. Most desert animals are nocturnal which means they only come out at night. They burrow themselves deep in the sand where its cool during the day.

Waves, especially during severe storms, erode shorelines by washing away sand, rocks and soil.

Lighten ship; people need to get off so that you don't damage the hull further. What did you run aground on, rocks or sand and dirt? If rocks, check immediately for leaks; you don't want to get back out into deep water and THEN sink. If it's a small boat, do you have a diving mask? Can you check the outside of the bottom of the boat and see if there's any damage? In any event, you probably want to get back to port or the dock and do more thorough inspections there.

During movement water is faster than sand and during cooling sand is faster than water.
It is so because the sand causes friction. So it slows down. Water in the sea has much less friction, that is why the boat just races along the water.
The force used when you step from a boat creates an equal reaction on the boat, which has very little friction with the water. If the boat were on the beach, friction with the sand would prevent it from moving very much.
Switch off the onboard engine, or lift the outboard motor clear of the water. Carefully check for hull damage that can cause leaks. Deal with any injuries by using first-aid, or phone emergency, if there are bad injuries. What follows next depends on the size and weight of your boat. What are you grounded on? Is it soft sand, pebbles, rocky shore? If sand, and your boat is not too large or weighty, it may be possible to push the boat back into the water from the bow. Or you could try rocking the boat to form a water filled hollow. Or you may need to phone for assistance!

because the sand is harder and water is very smooth and just sort of molds to a shape so it slips around the boat easily Edit: Because the sand causes friction. So it slows down the boat. Water in the sea has MUCH less friction, that is why the boat just races along in the water.

because the tide rise and particles of sand are washing away making the boat eventually move back into the water
to keep out sand during sand storms :)
