Water Cycle EXAM

The water cycle starts with evaporation, which is when the water from lakes, rivers, oceans or any other body of water turns into vapor or steam and rises into the air.  Ttranspiration also ends up putting more evaporated water into the air after the water comes up from the roots of the plants and to the surface where it evaporates.  Condensation is the opposite of evaporation.  When the water vapor becomes to heavy and the temperature drops the gas forms a liquid, water droplets.  Once the the temperature is right the water droplets become bigger and they fall to the earth, which is precipitation.  Precipitation brings the water back down to the earth where surface runoff begins.  Surface runoff happens when the precipitation hits earth and runs of the surface of the land toward body's of water that they were originally from.  If the water isn't going through surface runoff then it is going through infiltration which is when the rain water is absorbed into the ground.  From the ground the water will either stay there and become groundwater, our surface again creating springs in low downhill areas. 

A watershed is when water flows into a body of water, such as a lake, river, stream or ocean.  Our surface water features normally come directly from rain or from surface runoff.  The water flows into the body's of water that are close, and from there depending on the body type that it has flowed into it might continue to flow downstream.  Groundwater seeps into to ground and from there travels through different aquifers.  Aquifers can range from many different sizes under ground.

Rivers and Streams are classified by morphological similarity's, which can change over time.  When a river goes through erosion materials are moved along the bed of water and collides with other materials, which then breaks them down.  Flooding becomes a lot more likely when so many trees and forests are cut down, because run off water from precipitation can get to the water a lot quicker making it easier for the water to overflow, creating a flood.  A lot of floods take place because of decisions and actions made by humans.  On the other hand erosion is normally a natural process that happens.

The Earth in Space EXAM

Our solar system is located within the Milky Way galaxy.  Our galaxy has around 400 billion stars within it, with many clusters and nebulae.  Our Galaxy is 100,000 lightyears in diameter.  Becasue the Milky Way is a spiral galaxy it has what scientests call arms.  Our solar system is located in one of the arms, and it happens to be one of the smaller ones.  It is either refered to as the Local or the Orion Arm, which connects two other larger arms that make up our galaxy.  Being located within an arm of the galaxy we are toward the outer part of the Milky Way.  Our solar system is about 20 light years above the equatorial symmetry plane.  Our solar system is thought to be about 4.5 billion years old and we as humens have only been around for a few million of them.

The Big Bang is when astronimers said that there was a sudden explosion of all energy and matter that caused an expansion.  It is said that all space and even time began or started at this point.  13.7 years ago the big bang occoured.  600 million years after the big bang the forst atoms were formed which made it possible for galaxies and other features like our planets to form.  So after the big bang there was space, matter, energy and time for our universe to form and become in motion with eachother.

Observations of the cosmic microwave background have helped to determine the age of the universe, because it helped to discoever that sending a satalite into space to read the radiation that was emitted  into the universe coming back to the earth showing different cold and warm spots.  The size and heat of the spots that appear in the pictures helped scientists to discover how old our universe is.

Connection of 2 Green Book Climate Labs

For Activity 1 we found out what heats faster and cools faster water, sand or dirt.  After conducting the lab we discovered that all the different substences heated to an extent and then cooled back to around the temperature that it started.  We found that the water heated the slowest and that the dirt and sand heated at the fastest rate.  They all slowly cooled down.  I expected that the sand would kinda heat up quickly just from expiriences from the beech, but i thought that water would heat a little faster.

In Activity 4 we tested and measured how well the 3 different matirials water, light soil and dark soil reflected the heat given off by a light.  We found that it didn't matter which matirial it was that if it had the painted cloud over it that it reflected the heat a whole lot better than the ones without.  I thought that would be what happend, just because we expirience the same thing here on earth.

The small scale labs that we do help represent our climate on earth, becasue the same things apply.  It all explains why we have cold days and warm days.  With this information i could help to explain why when it rains it tends to cool off, but when it stops raining it warms up a little bit and becomes humid.  It would help to explain the tempereture that we expirience rain.

Bad Astronomy Post

     A comet has a tail behind it that could contain sand, ice, and rock.  I was right by writing this down as a true fact, becasue that's really what follows behind a comet while orbiting in space.  Another fact that I put down underneathe the true facts was that the astronot was blinded and that his skin was so badly burned by the suns light.  I was right for the fact that the suns rays can damage your eyes, and if your close enough u can be burned by it, but being that far away from the sun in the movie he should not have been injured that badly.
     In the movie there were also things that were false, one was that you wouldn't be able to hear any noise on the comet, becasue there isn't any air in space.  So i was right about that one.  Another thind that was false in the movie was that you can't walk on an astroid like you would do on earth, because of the gravity difference, so i was right also when saying that was wrong.
     A misconception that people think about stars at night are that all stars emit just white light, and honestly I head heard that they didn't, but I still thought that they just let off white light.  That was wrong because it turns out that all stars give off all the colors of the rainbow.

Climate Inquiry

1.  Climate is like the average temperature of weather of an area or location over a long period of time.  Some people think that weather and climate are the same thing, but really they aren't.  weather is the events that happen in an area, and climate helps to explain the weather that we experience.  For example if you were to look out the window and  examine what it's like outside for one day you would know the weather, but if you were to look out the window for many weeks or months in a row and examine the weather then you would have the climate of the location.

2. Climate change is the seasonals changes that take place in an area over a long period of time.  Ecosystems are essentially created by the climate changes that take place in an area.  Also humen economies and cultures depend on the climate changes that take place in an area.  Because so many things like the way that we live our lives is linked and related to climate, what we do depends on the climate change that takes place.

Sewer Treatment Blog

At the sewer treatment plant yesterday the man walked us through the process of treating the water.  He told us how the water entered the plant, and that the first biuling it goes through is the first biulding you see when you enter the area.  Then from there it goes to an area where it is treated.  The water goes through a very long cycle before it is entered into the river.  The water sewer treatment plant in our town has a secondary cleaning system, which isn't how it was origanally biult, but was added on.  Also i learned that the big tank that they have will fill up in about twelve ours if it needs to be used.  He also showed us the lab that they use to test the water, and do any other tests that need to be ran at the plant.
 I thought that it was cool that we all got to go and recycle things.  For me it wasn't the first time, because my family recycles plastic, aluminum, glass, paper and stirofoam.  On top of that we also have our own compost bin at our house, so we're pretty much an eco-friendly family.
