Offshore

Offshore drilling is drilling for oil in the ocean.

Offshore drilling isnt good because a pipe can burst and kill sea life.

Offshore drilling is good because the earth soil can have time too heal from all the deforestation due to gas.

I believe that offshore drilling is very bad, but then again the Earth and its people need it.

Astronomy











My favorite part of science has been astronomy. I liked the stars and the galaxies. The spiral,elliptical and irregular are types of galaxies but my favorite is the spiral galaxies. The spiral galaxies are in the andromeda galaxy.



Oceanography when we learned about offshore drilling.











Geology when we started the sedimentary rock examples they are rocks layered in Earth that can be dated by radio carbon or radiometric.






Mertology is when we studied the different boundaries and times like continental polar air masses.
