Blog Reviews.

Emily Swearinger's blog on AIR POLLUTION.
learned -
1. The greenhouse gas effect captures solar radiation in the atmosphere.
2. Greenhouse gases can be deadly to plants.
3. Outdoor pollution is any air born pollutant.
Worst - It's hard to tell where the paragraphs start and end because there's no spaces or indents. It's kind of boring.
Best - I'm curious about pollution because i know it effects us all.

Cody Stoner's blog on GREEN HOUSE GASES.
learned -
1. the main four types of green house gases are water vapor, carbon dioxide, methane, and nitrous oxide.
2. With NO greenhouse gases, we would have no atmosphere like Venus, Mars, and Titan.
3. Water vapors account for 66% of greenhouse gases.
worst - He didn't have any pictures.
best - It was interesting, and i actually learned from it.

Carleigh Nobach's blog on LOCAL WEATHER HISTORY.
learned -
1. Humidity may lead to health issues.
2. Scientists use satellites and radars and sensors to measure the earth’s atmosphere waves.
3. Certain earth weather conditions, acid rain, volcanic eruptions, and earthquakes, have caused the earths ground to split and natural land to be destroyed.
worst - Bad grammar.
best - It made me laugh.

Cyclones.

3.My research was on cyclones. Cyclones are revolving storms caused by winds in a central area. They occur in times low atmospheric pressures. When they occur in the northern hemisphere, they are called either hurricanes or typhoons. Cyclones typically develop over warm seas near the equator.

movie - Cyclones typically occur around the equator. They can be tracked by weather patterns. A new type of super computer had been created to track such events. When there are drops in pressure and wind changes, the super computer can predict where, when, and how long a storm may last. A cyclone that happened further south than any other recorded cyclone was predicted by this super computer.

2. Cyclones are basically large revolving storms. Heated air rises and cool air dives at the same time. Moisture collects and they begin to condense into thunderclouds. When the cool air dives air begins to bend and spirals into a circle. The middle of cyclones are called an “eye.”

5. Weather warnings can be issued on television or on radios, so if you live in an area with the possibility of cyclones, you should check regularly. Houses can be completely demolished by winds and underground water pressure during cyclones. When the storms are bad, you may even be evacuated and moved inland. Cyclones are very dangerous. Winds from 70-80 mph can occur, and knowing your local evacuation plans may be crucial.

5. If you live in an area where cyclones are typical, it would be best to keep your momentos in large rubber storage containers so you could take them with you. Listen to the radios before and after for warnings. Turn off your water, electricity, and make sure people know where you are. If you have time, you may make sure to raise your belongings off the floor to protect it from floodings. Make sure to have protective clothing, blankets, or sleeping bags so you can give yourself some shelter.

4. The eyes of storms are calm and cloudless. No rain falls in the eye and the winds are low. In the northern hemisphere, cyclones are called hurricanes or typhoons. They are different from those in the southern hemisphere because hurricanes and typhoons occur counterclockwise. Typhoons, which occur in the southern hemisphere, spin clockwise.

1. For these storms to develop, the sea’s surface temperature must be at least 26 degrees Celsius. The most dangerous and life taking occurrences from the cyclones are the winds. They tear down trees and collapse houses. The cyclones spin because the Earth spins. The earth spinning on it’s axis is the reason why the storms spin opposite directions depending on where they are.

When writing my paper, I found out what exactly cyclones are. I found out about how cyclones are created and how they work. I learned the highest risks of cyclones and what causes them. Before this paper, I thought that cyclones were completely different from hurricanes and cyclones.

2100 Weather Ahead Video.

When we started this video, there were a few things that i had already known ahead of time. I know that global warming will eventually cause many problems with our planet and it's weather. There will be violent storms, more pollution, coastal floods, and many more reprecussions if we dont do something about our environment and how we treat it. Hurricanes, cyclones, and typhoons are all the same thing. They typically occur closer to the equater.

I learned new things from this video as well, though. There is a Earth simulator made up of 1500 computers that predicts future developements in weather. This super computer predicts weather. It shows future temperatures, winds, and water currents around the globe. This computer predicted the first ever hurricane that occured next the Brazil in the ocean. It was the furthest hurricane that far south ever. The computer predicts a world wide increase of storms and category 5 hurricanes. It's impressive, really. It's humans fault for all of the pollution and green house gases that we've added to the atmosphere.

This greatly applies to my topic because cyclones are my topic. Many more will occur in the future if we don't do anything to help our environment fix itself. The storms will occur more often and with more force than before and we need to prepare ourselves against such tragedies. With everything in the world going through crisis, i think it's about time someone does something about it.

The Sun's Light.

In the lab that we did today, i learned how the sun's light applies to the Earth. My parents told me the same thing that i learned in the lab today when i was younger, though. I knew that it was colder in the winter because the Sun's light was at an angle from the Earth being on an axis. When the Earth rotates on an angle, the Sun only hits it on an angle.

One thing that i learned today, though, was that when the Sun's light IS at an angle, it spreads over more land. Which explains day light savings and such. When the Earth's angle changes because of the axis, it rotates between the area being lit. The Earth's axis isn't straight, its tilted to one side but not side ways from the Sun.

This lab applied to us because it effects everyone. Unless you're constantly traveling and following the Sun, this applies to you. Right now, seeing as it's winter, the Earth's axis is tilting us away from the Sun. Making us, in turn, get the Sun on an angle. Covering more land, but with less intensity and heat.

BLOG ACT 1.

I thought the lab was kind of cool because my hopothesis was wrong and i didn't expect it to be. I learned something new.

I learned that Sand heated faster than the dark soil, which i didn't expect. Then the dirt, and then the water. I thought that it would be dark soil, sand, then water.

I'm not sure how this really applies to cyclones. Cyclones are my topic and i don't really know anything about cyclones yet, that's why i chose it.

climate change.

The climate changes from many different factors. Burning coal, oil, and natural gases release carbon dioxide into the atmosphere. It can also affect the climate in other ways. It could even change the severity and the duration of storms or droughts. Many human activities affect the climate as well, though. Cutting down forests and raising cattle are examples too. Wastes being recycled and waste prevention reduce methane emissions, save energy, and increases the carbon produced in forests. If there are any rapid changes in the environment’s climate, then there will be a very large effect on plants and animals in their natural environment.
