What do you mean when you say that water wets a surface such as the surface of sand?

The term "wetting" has a specialized meaning in surface chemistry. We usually say that a liquid "wets" a surface if the contact angle a droplet of the liquid makes with the surface is less than 90 degrees, and that it "doesn't wet" a surface if the contact angle is 90 degrees or more.

How are wind erosion to water erosion different?
the answer is that water erosion wets all the land but while wind keeps it dry.
Why does the well water from hot water tap looks cloudy but cold water is clear?
Becauseof the steam, when the water heats up it forms steam. is you feel the steam that comes out of a kettle, it's very hot and wets your hand (when your hand is wet it means the hot water has cooled again)
How does rain turn into soil?
Rain doesn't turn into soil. It wets the soil, then some of it percolates down through it on it's way to the water table. Some of it is used by the growing things in the soil (if any) and the microbial life in the soil, and some of it evaporates back into the air.
What happens to rainwater?
It falls down wets the ground and vegetation supply's drinking water for animals some evaporates back into the air mediately it runs into rivers fills lakes resupply aquifers and dams then whatever doesn't make it into the ground runs into the sea in some areas humans collect it in dams to supply their needs, after they are through with converting it into sewerage they put most of it into the sea. In effect all rain watter ends up in the ocean eventually, evaporates clouds, rain, runs of to the sea, and then it starts again.
What is inside of snow?
Snow is frozen precipitation, formed from ice crystals within clouds. Snow is normally pure, and like rain, provides a supply of fresh water. In cold climates, snow can compact and refreeze into ice, forming massive glaciers as in Antarctica. Normally snow falls in winter. It may be produced in large quantities from moist air that is rapidly pushed to a higher altitude, or from very moist air over large bodies of water. Snow is usually annoying to adults because it is cold, and sticks to surfaces and wets them. Snow accumulations have to be removed from houses and roads. Kids enjoy playing with the snow because it will usually clump together. Snow can be made into snowballs and snow forts, for snow fights, or rolled into larger balls to form snowmen and other figures. Snow is recreationally used in skiing, sledding, snowboarding, and with snowmobiles.
How does water affect mass wasting processes?
I believe It changes the affect on the earth's surface, for an example: Dry sand grains are bound mainly by friction with one another. Small amounts of water increase the cohesion among sand grains. Saturation reduces friction and causes the sand to flow.

Why would water be a greater height in a narrow tube placed in a breaker of water and wider tube?
The surface tension of water is such that it always wets things it is in contact with slightly higher than its surface - it wants to climb things. This can be seen at the very edge of the water in a wide vessel, where there is a slight upward curve in the surface. In a tube, however, that curve extends to the middle of the surface, causing it to rise, which wets the sides of the tube higher, pulling the water upward until a balance with gravity is reached. This is called capillary action. In a narrow tube, such as the veins of a plant, it can be powerful enough to raise the water level many feet. The narrower tube in your example is exhibiting capillary action, and the larger vessel is not.
