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.

Oxidation is the breakdown of rock due to oxygen and water. Physical Weathering vs Chemical Weathering. 1  Physical weathering does not change the chemical composition of the rock whereas chemical weathering changes the composition. 2  Physical weathering may result due to temperature, pressure, snow, etc. whereas chemical weathering mainly takes place due to rain.
