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.

Strata volcanoe vs. shield volcanoe

Stratovolcanoes, also known as composite cones, are the most picturesque and the most deadly of the volcano types. Their lower slopes are gentle, but they rise steeply near the summit to produce an overall morphology that is concave in an upward direction. The summit area typically contains a surprisingly small summit crater. This classic stratovolcano shape is exemplified by many well-known stratovolcanoes, such as Mt. Fuji in Japan, Mt. Mayon in the Philippines, and Mt. Agua in Guatemala.

Gulf Stream

The majority of the Gulf Stream is classified as a western boundary current. This means that it is a current with behavior determined by the presence of a coastline - in this case the eastern United States and Canada - and is found on the western edge of an oceanic basin. Western boundary currents are normally very warm, deep, and narrow currents that carry water from the tropics to the

The Gulf Loop Current, a circular stream of warm water that runs through the Gulf of Mexico during the spring and summer, is basically the highway upon which the oil slick would travel. The loop pulls currents from the Caribbean Basin and around the Gulf of Mexico. After water is dragged south and through the Florida Strait, it enters the Atlantic Ocean and joins with the more powerful Gulf Stream.

Plate Tectonics

The map of the Earth is always changing; not only are the underlying plates moving, but the plates change in size. Also, the sea level changes over time as the temperature on Earth varies and the poles melt or freeze to varied extents, covering or exposing different amounts of crust.

The theory of plate tectonics has done for geology what Charles Darwin's theory of evolution did for biology. It provides geology with a comprehensive theory that explains "how the Earth works." The theory was formulated in the 1960s and 1970s as new information was obtained about the nature of the ocean floor, Earth's ancient magnetism, the distribution of volcanoes and earthquakes, the flow of heat from Earth's interior, and the worldwide distribution of plant and animal fossils.

Ocean Water

The ocean waters can be divided into three layers, depending on their densities. Less dense waters form a top layer called the surface mixed zone. The temperature and salinity of this layer can change often because it is in direct contact with the air. For example, water evaporation could cause an increase in salinity, and a cold front could cause a drop in temperature.

There are four temperature scales that give us a relative understanding of the heat in the object or system we are measuring: Fahrenheit, Celsius, Kelvin, and (the less-common) Rankine. The Fahrenheit and Celsius scales are based on two fixed points, the Kelvin and Rankine scales are based on one.

The Water Cycle

The earth has a limited amount of water. The water keeps going around and around and around to what we call ''The Water Cycle''. Water can be in the atmosphere, on the land, in the ocean, and even underground. The water cycle keeps the water on earth balanced.
