It is important to drink little and often to keep hydration topped up every hour! It isn't adviseable to drink it all in one go! It is best to sip water through the day and never drink more than 2 pints in one hour. Do not excede 6 pints in any day. If you are a runner or professional athlete then you may need to trust your judgement and drink more than that but never excede 6 pints, but on average, 4 pints (or 2 litres) of water per day is recommended for the average person.
Weathering vs. Erosion. The main difference between weathering and erosion lies in where the process takes place. Weathering degrades a rock without changing its location. Erosion, on the other hand, causes rocks -- or particles of rock -- to be carried away from their original locations and deposited elsewhere.Weathering often leads to erosion: weathering breaks the rock down into small pieces that are easier for wind and water to carry away.rosion, on the other hand, causes rocks -- or particles of rock -- to be carried away from their original locations and deposited elsewhere.

Erosion is the process that breaks things down. As far as we're concerned, erosion is the breakdown of the continents and the land around you. The overall effect of breaking down and weathering the land is called denudation. Denudation is the process of erosion. In nature, large things are broken down into smaller things. Boulders become sand. Mountains are rained on and become hills. The pieces of the mountain become smaller pieces and go down the sides of hills. Weathering and erosion always happen in a downhill direction. Erosion is an easy idea to understand. If you see a rock, pull it out of a mountain. Then throw it down on the ground. You are now a part of the erosion of that mountain.
