Stand and Deliver

Stand and Deliver is an important movie becaue it shows that it dosent matter where u came from, where your parents are from, where they work, where you live, or what your last name is. It shows you can get good grades and do good if you work hard and achieve all of your goals.

Also in Stand and Deliver Mr. Escalante has faith in his kids and that shows the kids that they can do whatever thry set there mind to.  

Earth Science (Stars)

Stars are giant nuclear reactors. In the center of stars, atoms are taken apart by tremendous atomic collisions that alter the atomic structure and release an enormous amount of energy.

This makes stars hot and bright. In most stars, the primary reaction converts hydrogen atoms into helium atoms, releasing an enormous amount of energy. This reaction is called nuclear fusion because it fused the nuclei (center) of atoms together, forming a new nucleus. The process of forming a new nucleus (and element) is nucleosynthesis.

Stars can live for billions of years.

Norhtridge Earthquake

   

 

The Northridge earthquake occurred at 4:30 a.m. local time on January 17, 1994. Northridge is located about 30 km northwest of Los Angeles.

This earthquake had a 6.9 moment magnitude.  The duration was about 10 seconds to 20 seconds.

The Northridge earthquake was the worst earthquake in the Los Angeles basin since the San Fernando earthquake in 1971, which had a 6.7 magnitude.

The earthquake occurred along a "blind" thrust fault, close to the San Andreas fault. Note that a blind fault is a fault which does not extend to the surface. In other words, it is buried.

Japans Earhtquake

A severe earthquake struck the north-east coast of Japan on 11 March, causing a major tsunami and serious damage across northern Japan.



Tokyo Electric Power Company has distributed a series of dramatic images showing Fukushima Daiichi Nuclear Power Station workers risking their health to repair the control room of reactors no. 1 and 2, heavily damaged by the devastating March 11  earthquake and tsunami in northeast Japan.

Earthquake Hazard in California

The first strong earthquake listed in earthquake annals for California occurred in the Los Angeles region in 1769, probably near the San Andreas Fault. Four violent shocks were recorded by the Gaspar de Portola Expedition, in camp about 30 miles southeast of Los Angeles center. Most authorities speculate, even though the record is very incomplete, that this was a major earthquake.


Forty persons attending church at San Juan Capistrano on December 8, 1812, were killed by a strong earthquake that destroyed the church. Many mission buildings were severely damaged there and at San Gabriel. The shock probably centered on a submarine fault offshore

Seismic Waves

A seismic wave is an elastic wave generated by an impulse such as an earthquake or an explosion.

Seismic waves are wavesof energy that travel through the earth, for example as a result of an earthquake explosion, or some other process that imparts low-frequency acoustic energy.

The P waves move in a compressional motion similar to the motion of a slinky, while the S waves move in a shear motion perpendicular to the direction the wave is travelling.
