Favorite Earth Science Topics

Geology- Chemical & Mechanical Weathering is my favorite subject in geology. Chemical Weathering is the transformation of rock into one or more new compounds. Mechanical Weathering is when the rock changes, but keeps it's mineral composition.

Meteorology-Air Masses is my favorite subject in meteorology. The air masses include the mP,mT,cP,cT air masses.

Oceanography- My favorite topic in oceanography is about the ocean basin floor. The ocean basin floor has deep-ocean trenches , abyssal plains, seamounts, and guyots.
Astronomy- My favorite subject in astronomy is the Solar System. The Solar System has 8 planets, an Asteroid Belt, and a Kuiper Belt.

Greenhouse Effect

What is the greenhouse effect?

The greenhouse effect is when greenhouse gases trap heat and keep it in the lower atmosphere instead of rising up.

How are the greenhouse gases produced?

Pollution

How does the greenhouse effect impact our lives?

Global Warming

Is the greenhouse effect good or bad? Why?

Bad, b/c it can cause global warming and melt all the glaciers and holes in the ozone layer.

Astronomy Topics

1. Ultimate fate of the universe
The Ultimate Fate of the Universe gives a theory on how the universe will end. It says that the universe will undergo a theory called the Big Crunch. There are many other theories, but this one is the most believed in. The Big Crunch states that the universe will expand, then shrink into the size of a softball. The end of the universe is said to end billions of years from now.

2. Black Holes
Black Holes are objects so dense that nothing in the universe can escape it's gravitational pull. The black holes are located in many places, there is a black hole located in the center of the Milky Way. Black Holes can be known as the most violent and energetic objects in the universe. Black Holes form from collapsing stars and are tiny, and get larger as it sucks in objects around it.

3. Search for Extra-terrestrial Life (SETI)
The Search for Extra-Terrestial Life (SETI) is when scientists search for life outside of Earth. Scientists use radio telescopes to search for "aliens", and if a signal is picked up, that usually means a life form is out there. Scientists came to the conclusion that life could only survive on and Earth-like planet like Mars. Mars has been studied for years for life, but have found nothing.

4. Astrobiology
Astrobiology is the study of the living universe. This includes humans and possibly aliens. Astrobiology supports the evolution theory, which is the thought that humans evolved from apes. Astrobiology also states that life would most likely be found on Earth-like planets, and it also suspects that Mars could have previously had life forms on it, or could currentlty contain them. The study of astrobiology is some what like SETI, but studies all life forms.

5. Star Constellations

Star Constellations are groups of stars that form pictures. These constellations have been used to represent zodiac signs. Different countries like China and India have different ways in using the constellations. Constellations can be confusing and tricky to the eye, and hard to point out because of the millions of stars in the sky. The constellations are hard to identify for some people, because the stars must be precise if you want to see the picture correctly.
