FAVORITE TOPIC IN E. SCIENCE

My favorite topic from this year in Earth Science would be the astronomy unit. The astronomy unit talked about the universe and how it was created. It also talks about how there could be other life forms in other galaxies and how we are searching for them. What i thought was most interesting were black holes and worm holes. I found this interesting because that wouls just be awesome if time portals did exist and what the inside of a black hole could really look like. I mean thats just cool how u could look up at the sky and watch objects float then suddenly disappear because they fell into the boundary of a balck hole. This topic also dealt with how scientist think the universe will come to an end. They believe in the Big Crunch Theory. There's just so much to explore in space and I can just think of the possiblities of what could really be waiting for us to discover it.

EXTRASOLAR PLANETS

1. Four ways that atsronomers can detect extrasolar planes are Radial Velocity, Astrometry, Transit Method, and Optical Detection.

2. The one I choose is Transit Method. This method explains that when a planet passes a star and its observers line of sight, part of the star will be blocked by the planet. This reduces the star apparent brightness. Highly sensitive detectors would detect that change in brightness thus knowing theres a planet nearby.

3. More than 1o planet have be detected using this method.

FAVORITE PLANET

My favorite planet would be Earth. Earth is my favorite planet because it supports life. I have lived every day of my life on this beautiful planet. It is unique in its own way and has so much to offer. There are many planets and animals that have their lives supported by Earth. This planet is important to everyones life. Without Earth here to support us, we would have nowhere else to go.

PLUTO

To me Pluto is a planet. It has some of the same characteristics that the other eight planets contain. It is sphere shaped and just because it has a different orbit than the other planets and is a bit smaller doesn't mean you should take the name planet from Pluto. Since i was in elementary school i have always been taught that Pluto was a planet.

MONSOONS

1. A monsoon is the seasonal reversal of wind.

2. Two factors that affect monsoons are thermal blow and the Bermuda High.

3. Two reasons why monsoons could be considered a good thing because they can bring water to crops in dry areas and the use of brust and breaks.

4. Two negatives of monsoons are intense heat and thunderstorms.

5. So many people died in India because of constant rainfall from Monsoons which caused lots of flooding.
6. I think that monsoons are good and bad. They can be very helpful but can also cause lots of damage.

CONDENSATION

Five examples of condensation and their nuclei are

1. A window : from water vapor in the air


2. a mirror : steam from the shower


3. grass : morning dew


4. water bottle : condensation form being in the fridge

5. glass : when water vapor touches glass

GLOBAL WARMING

Global warming is an increase of the average temperature of the atmosphere. I do believe in global warming. I feel that the temperature in the atmosphere is rising and this does cause lots of damage. Pollution contributes to global warming such as cars releasing toxins. Carbon dioxide also leads to global warming. carbon dioxide collects heat from the sun and heat the Earth. Spaying hairspray in a certain can can also cause global warming. Some people may not believe in global warming. This may be because they feel that CO2 has nothing to do with the earth's temperature rising. They also feel that this is a natural process and its just because of the sun.
