My favorite parts of earth science




Rocks and Minerals were my favorite part of Geology. I liked learning about the different forms and characteristics about them.






Oceanography was my favorite part of earth science because i love looking at water sences and learning about them.







Of the atmosphere section, my favorite part of it was clouds. I liked the way they formed and moved. They were able to change the wearther and temperature.









My favorite part of astromony was learning about Saturn and its rings. The best part of the is its ring. There seven divisions of the rings and are made up of different particles like dust, rocks, icy objects and others.

The Greenhouse Effect

1. Greenhouse Effect is when the earth's atmosphere traps solar radiation, caused by the gases that allow incoming sunlight to pass through but absorb heat radiated back from the earth's surface.



2. The three most common types of gases are carbon dioxide, water vapor, and methane.



3. They have formed because the earth's temperature has inceased 5 degree.



4. It makes the temoerature hotter on the earth which makes the seasons hotter.

5. The greenhouse effect is good because if it wasn't there, it would be freezing all year.

Off Shore Drilling

1. Offshore drilling is a drilling for oil or gas in an ocean, gulf, or sea, usually on the Outer Continental Shelf.

2. Offshore drilling is good because it brings money to people who work on the sites and owners and because we use the oil to transport to places.

3. It is bad because oil can spill in the ocean and can kill millions of sea animals.

4. I think that offshore drilling is both good and bad because it can spill and kill animals but it also heats up homes and runs cars.
