Electromagnetic Spectrum

The electromagnetic spectrum is the complete range of electromagnetic waves placed in order of increasing frequency. Radio waves, microwaves, radar, infrared rays, thermogram, visible light, ultraviolet rays, x-rays and gamma rays are all a part of the electromagnetic spectrum. Radio waves are the electromagnetic waves with the longer wavelengths and lowest frequency's. Microwaves are radio waves with the shortest wavelength and highest frequency. Radar is the system that uses reflected radio waves to detect objects and measure their distance and speed. Infrared rays are electromagnetic waves with wavelengths shorter than those of radio waves. Thermogram is an image that shows regions of different temperatures in different colors. Visible light is electromagnetic waves that you can see. Ultraviolet rays are electromagnetic waves with wavelengths just shorter than those of visible light. X-rays are electromagnetic waves with wavelengths just shorter than those of ultraviolet rays. Gamma rays are electromagnetic waves with the shortest wavelengths and highest frequency. One type of visible light is a lamp. Microwaves are used in space to learn about the structure of galaxy's. Hot gases in the universe give out x-rays.

SOCIAL STUDIES- helicopter crash

All eighteen people survived the helicopter crash. There was a helicopter crash today near Scotland. There were 16 passengers and two crew people. Everyone survived by being recued by either a boat or another helicopter which was in the area.
The helicopter crashed off the coast of Scotland. The helicopter fell 120 miles east of Aberdeen while heading to an offshore platform where they were going to land. Everyone was recovered from the water and they believe that there was no severe injuries. People who were aboard the helicopter were rescued from the water either by another helicopter or by boat. The helicopter was heading for a platform which was home to many offshore oil rigs. The crash happened at 6:43 p.m. (1:43 p.m. Eastern time) today. This helicopter is used to bring people to and from oil platforms in the North Sea. This helicopter is called the Super Puma and is reported to have good safety records. The weather was good except there was a little bit of fog. All passengers survived.
The Super Puma helicopter went down around 125 miles east of Aberdeen in Scotland at around 6.40pm today. Three people were recuded from another helicopter while the other fifteen were brought to safty by a platform lifeboat. There were a few minor injuries but not major injuries. There were sixteen passengers and two crew members. The helicopter crashed into the water. The weather was okay but there was darkness and many clouds. The people aboard the helicopter were very thankful for the resuers.

Mount Redoubt

Mount Redoubt in Alaska is expected to erupt very soon. They expect based on the past behavior of this volcano that this activity is going to culminate in an eruption. The activity includes small earthquakes and continuous volcanic tremor. On Sunday scientist raised the alert status to "watch level." "Watch level" means that the volcano has reached certain heights where it is supposed to erupt. The volcano shouldn't cause severe damage to anyone. Falling ash is a problem though, people should wear a mask to protect themselves from it. Mount Redoubt last erupted about 20 years ago in December 1989 and it lasted until April 1990. Geologist expect this time to be a similar or smaller than the one in 1989.

Earthquake-SOCIAL STUDIES

A small earthquake hit Northern New Jersey on Monday February 2nd 2009. The earthquake struck a few miles away from Morristown. An earthquake with a magnitude of 2 hit Phillipsburg, New Jersey on July 28. A magnitude of 2.6 earthquake hit Sussex County, New Jersey on Feb. 17, 2006, and another earthquake, with a magnitude of 2.1 hit Morris County on Dec. 10, 2005

The earthquake hit Northern New Jersey at around 10:30 monday night. The earthquake had a magnitude of 3.0. The earthquake did not cause much damage and no one was reported injured. A earthquake which has a magnitude of 3.0 is rather large for New Jersey. Many people described that the earthquake felt like a bomb or a very loud thump. Someone working at a Exxon station in Rockaway, New Jersey said that the earthquake felt like it lasted two to three seconds.

The earthquake which was a magnitude of 3.0 hit at 10:34. Some had feared that a plane of truck had crashed. Dover, Wharton, Denville, Randolph, Mine Hill and the Rockaways in Morris County were hit with the earthquake the worst. The earthquake was about two miles underground. "For New Jersey or the Northeast, a 3.0 is fairly big." This earthquake is big for New Jersey but in California this would be nothing to them."But in California, it would be nothing, just a small event," The average earthquake is five to six miles under ground. Since Monday's earthquake was only two miles underground it resulted in more shaking and had more people feel it. If it was deeper than it might not have been noticed. Earthquakes are most common in highlands region in the state's northwest corner.
