If the Earth is covered in land and water, does the composition of these materials affect anything that the Earth experiences? For example, if the Earth is mainly covered in water, does water have a different relationship with the Sun that the land does? Only time will tell. So far, students have uncovered that the Earth is mainly made of water (nearly 70%) and that about 97% of that water is salt water. Whoah!
Starting tomorrow, I will be on maternity leave, so my blog will resume next school year!
