1. Rocks are a airbetweendifferentgrainsgranitemanymixturenoporoussandstonespacestexturestrapped of mineral airbetweendifferentgrainsgranitemanymixturenoporoussandstonespacestexturestrapped.

2. Rocks have two main airbetweendifferentgrainsgranitemanymixturenoporoussandstonespacestexturestrapped.

3. When a lump of airbetweendifferentgrainsgranitemanymixturenoporoussandstonespacestexturestrapped is put in water it causes airbetweendifferentgrainsgranitemanymixturenoporoussandstonespacestexturestrapped tiny bubbles of air to form in the water because the rock is airbetweendifferentgrainsgranitemanymixturenoporoussandstonespacestexturestrapped.

4. However, when a lump of airbetweendifferentgrainsgranitemanymixturenoporoussandstonespacestexturestrapped is put in water, airbetweendifferentgrainsgranitemanymixturenoporoussandstonespacestexturestrapped bubbles of air are seen because there are no airbetweendifferentgrainsgranitemanymixturenoporoussandstonespacestexturestrapped between the mineral grains.

5. Sandstone has spaces airbetweendifferentgrainsgranitemanymixturenoporoussandstonespacestexturestrapped the mineral grains and the airbetweendifferentgrainsgranitemanymixturenoporoussandstonespacestexturestrapped air is released when it is put in water.

6. The airbetweendifferentgrainsgranitemanymixturenoporoussandstonespacestexturestrapped in granite are more densely packed and so there is no space for trapped airbetweendifferentgrainsgranitemanymixturenoporoussandstonespacestexturestrapped.

7. The differences in properties between sandstone and granite, suggests they were formed in very airbetweendifferentgrainsgranitemanymixturenoporoussandstonespacestexturestrapped ways.
