What is the purpose of polyurethane when finishing lumber?
Polyurethane is a sealant; it keeps water from absorbing into the wood by filling the microscopic pores and grains. If water enters the wood, it can warp and become unstable.
Which agents carry erosion products?
Wind, water, ice, and gravity.
How is water cycle altered during drought?
There is no precipitation during droughts. Water becomes scarce.
Where in a river from top to bottom can you find dissolved load suspended load and bed load?
Bed load will be the heavier stuff that will soon fall out of the flow - boulders, gravel, large grains of sand. Suspended load is the finer stuff that the flow can carry further, even as far as the sea, deposited as sand, silt and mud. Dissolved load is the chemicals that will remain in the water until mixed with salt water and become dispersed in the sea.
How fast does water need to flow to carry 2 mm sediment grains?
According to the findings of Hjulström, a velocity of about 10 cm/second is required to maintain transport of grains with diameter of 2 mm. About 50 cm/second are required to start moving a settled grain of that size. Note that these numbers are dependent on shape and density of the sediment. If styrofoam is your sediment the water doesn't have to flow at all to carry the grains and if you look at little gold nuggets the water has to flow significantly faster to carry the grains. This is one of the reasons why placer deposits form.
What is formed when rocks slide along a creck?
Rocks sliding along a creek, become rounded and broken into ever smaller pieces by the water action. They will eventually become grains of sand on the beach, if the water flow is sometimes strong enough to carry the grains to reach the sea.
When water combines with mineral grains do the grains become smaller or larger?
When water combines with mineral grains, the grains become larger. The increase in size of mineral grains strains the rock material and weakens it.
Wind and water carry sediment from one place to another during?
Erosion
How did Mesopotamia water their crops during a drought?
They developed an irrigation system to direct the water to where they needed it.
How many grains of water vapor equal 1 lb?

Why would a person carry a water bottle during a hike?
A person should carry a water bottle during a hike to avoid dehydration. Although water sources may be available on a hike the purity of the water cannot always be relied upon and a hiker should have a source of fresh clean water available at all times.
Did planet earth form from drops of water or grains of dust?
Grains of dust.
Soil texture?
The texture of soil depends on its particle size: clay-fine grains, very little space for water. sand- coarse grains, loose, water drains quicklysilt-medium grains, retains water.
How do pollen grains move in water?
pollen grains are attracted by a magnetic force
