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.

Weathering and erosion. Weathering is the process where rock is dissolved, worn away or broken down into smaller and smaller pieces. There are mechanical, chemical and organic weathering processes. Organic weathering happens when plants break up rocks with their growing roots or plant acids help dissolve rock. Once the rock has been weakened and broken up by weathering it is ready for erosion. Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity. Mechanical weathering physically breaks up rock. One example is called frost action or frost shattering. Water gets into cracks and joints in bedrock.
