Exam # 8

The Earth In Space
Shelby Cook
4th Hour




A) Our solar system is known as the Milky way galaxy and includes the Sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Pluto was downgraded and is no longer considered a planet. Each of the planets orbits around the sun in an orbit. An orbit is an elliptical path that a planet takes around the Sun. The Sun makes up around 99.85% of the mass in our solar system. Our galaxy also consists of an Asteroid Belt located between Mars and Jupiter. The inner four planets of the solar system are smaller in size, and have rocky surfaces. The outer four planets are considered the gas giants of the solar system, and are enormous in size and only have a solid core. The earth is 13.7 billion years old.

B) About fifteen million years ago a huge explosion started the expansion of the universe. People Called it the BIG BANG! They say it was an event that filled the universe with what we know today. The origin of the big bang theory came from Edwin Hubble. Who said our universe continues to expand. He discovered that a galaxy’s velocity is proportional to its distance. If a planet it two times away from us it spins two times faster.

C) The Cosmic Microwaves tell us a lot about how old the earth is. In the picture below the grey is a spotty pattern of microwaves emitted from the early universe. Sound waves take time to generate such a pattern which leads to the knowledge of our earth being 13.7 billion years old.

Final Exam #6

The Water Cycle
Shelby Cook
4th Hour

A) The water Cycle happens in all places and things. There are 8 different processes in the Water Cycle. Evaporation Is the process by which water changes from a liquid into a gas or vapor. It’s the primary way that liquid can get back into the water cycle. Transpiration Begins in a plants roots. The water moves from the roots to the leaves where it evaporates into the atmosphere. Condensation is when vapor in the air is turned into a liquid. The opposite affect of evaporation and transpiration. Precipitation is and form of rain, whether it be sleet, hail, snow, or freezing rain. It delivers atmospheric water to the earth. A portion of water that falls to the earth, including snow, soaks into the rocks and soil which is known as Infiltration. A portion of the precipitation that hits earth runs off into river, streams, ect. This is called surface runoff. It is very important because much water that was evaporated returns to the oceans. Groundwater is simply water that comes from the ground. Absorption is important especially for plants to regain the water they need to live.

B) Only 30- 40 percent of the snow and rain we see hit the ground actually goes back into the rivers, lakes, and streams. The rest goes into plants and Ground water which moves to nourish forests and replenish aquifers. Water Cycling cools the planet and cleans the air.

C) Streams Run into rivers that eventually run into the oceans. The same time the water leaves the river more is being run into the river. When winter snow melts the rivers are more likely to flood. The groundwater has taken on so much the river will take on more. Floods can make soil very fertile therefore the food is greater in amount and richer.

NASA

I created a nasa account. I have yet to do things with it

Nature trail

1. The boxes have maps in them
2. its much cleaner
3. there arent bees!
4. Trails are marked off
5. Much prettier

NASA

Light Curves, Spectra and Images.
Observing the lights is mostly the only way we can learn about them. If you graph different energies you can make a spectrum.
Quiz: 100%
Try this: The CD reflects a rainbow

X-ray Bianary Stars:
They emit x-rays. Contain 2 stars that orbit around their common center of mass.
Quiz: 100%
In an eclipsing binary, the brightness of the smaller, brighter star is greatest when its companion star, in this case the dark colored ball, is behind it.

BLack Holes:
DIstant and harmless things. Black holes cosume gas and little stars.
There is no quiz
there is no try this either

Spectral anylisis:
Display of elctromagnetic radiation. It was reintrodusedwhen newton decomposed the white sunlight into a spectrum of colors.
Quiz: 75%
there is no try this

nature walk

1. there was too much poison ivy
2. we should put the branches on the outside of the trail
3. there were lots of bx elder bugs
4. lots of lady bugs
5. lots of oak trees
6. Rocks
7.dirty signs
8.Bushes
9.Plenty of trees
10.Flowers
11.Mushrooms
12.Mosquitoes
13.Sparrows
14.Crows
15.smelled bad

The nature trail is a part of our community because people donated al ot of land the trail. It has lots of birds bugs and trees in it for the the community to learn about. it is great for classes to go and take a walk. The only problem is that it is not well kept. we should go back and help repair the nature trail

Climate junk

Global Warming...
The site provided is my source,
It says that global warming is affected by people and the eco system is diminishing. Climate change is one of the greatest threats facing the planet.
http://www.globalissues.org/issue/178/climate-change-and-global-warming

Global Dimming,
Its when fossil fuel use make clouds reflect the suns rays into space.less heat and energy reach the earth. it is belived that global dimming caused the droughts in ethiopia that killed millions.
