Some people think earthquakes and volcanoes erupt spontaneously while mountains appear randomly. However that isn’t the case- they are caused by plate tectonics. Plate tectonics are a scientific theory that pertains to the large-scale motions of the Earth’s lithosphere (the rigid outermost shell) and formed form extreme core pressure. The concept of plate tectonics developed during the early 20th century and is the study of the mass of the earth and how the masses correlate to one another. The plates pull and push causing continental drift, which affects the earth by causing earthquakes, volcanoes and mountains. There are seven major tectonic plates, and minor plates, that are composed of Oceanic Lithosphere the hard outer shell of the Earth’s crust. Through subduction the plates are carried to the uppermost mantle. Material is lost in order to balance the formation of a new crust along margins, by the sea floor spreading. This provides the Earth’s total surface to remain the same through out. Movements of the plates occur because of the Asthenosphere, which turns over hot rock for a total of ten centimeters a year; located under the lithosphere. Within the asthenosphere are convection cells in which slowly turns over hot rock. The cooled rock then turns sideways and moves parallel to the Earth’s surface before returning back into the subduction zones and reheating. When this happens it is called a divergent plate boundary. Tectonic plates are able to move because the Earth’s Lithosphere has a low density and a higher strength than the underlying Asthenosphere. The temperature gets intense to the point where magma convection currents cause heat to rise slightly near the Earth’s crust. Fault lines, small openings in the Earth’s crust, where large pieces of crust are moving in different directions. An earthquake occurs when two tectonic plates collide and is along the transformation boundary fault lines. How strong the earthquake is, or how violently volcanoes erupt, depends
1. What happened with Billy Deel and how was it a Catalyst for the family’s move?
After Jeannette gave back the ring to Billy he got angry and came to her house and fired at the children with his BB gun. The oldest, Laurie, came out with her father’s gun and fired at him but missed.
The police were called and the officer wanted everyone to go to the court house tomorrow morning. So that night the family packed up and left for phoenix. Billy serves as a catalyst for their move because without…

membrane separates the cells from their environment and each other while also regulating the material within each cell. 2. What are two distinctive physical features of phospholipids? Heads are polar (water soluble, hydrophilic) and tails are nonpolar (water hydrophobic).
Describe the conformation of the phospholipid bilayer of the plasma membrane. What abundant fluid leads to his conformation? Because the phospholipids heads are…

Subject Area: Science
Unit: How Things Move
Big Idea: Objects can move in many ways.
Instructional Objectives - GPS/Elements for the Week:
SKP2 Students will investigate different types of motion.
a. Sort objects into categories according to their motion (straight, zigzag, round and round, back and…
Answer the questions about this graph and what conclusions you would draw. See the back of your textbook for density values.
2. On your calculator or in Excel, graph the trend of Melting Point and Boiling Point. The graph should have the atomic number on the x-axis and temperature (MP & BP) on the y-axis. Place both on the same graph. See the back of your textbook for melting point and boiling point values.
3. Answer the questions about this graph and what conclusions you would draw.

Move is a unit that relates both to the writer’s purpose and to the content that he or she wishes to communicate. A step is a lower text unit than the move which provides a detailed perspective on the options open to the writer in setting out the moves in the introduction. This model has a major influence on research and the teaching of writing in ESP. According to Dudley Evans…
of life can be a bumpy one. There will always be twists and turns that can alter a person’s life, changing the course of their destination. Even though life can be tough, you have to draw upon your inner strength in order to persevere. The songs, “Move Along” by The All-American Rejects and “Good Riddance (Time of Your Life)” by Greenday sing about this message. The lyrics in their songs have many literary devices such as personification, repetition, symbolism and juxtaposition. The personification…
States of Matter.
What: Chemistry is the study of composition and properties of the matter around you.
Four States of Matter: Solid, liquid, gas, and plasma
Solid: Molecules packed closely together that vibrate in place
Ex: Tennis Ball
Liquid: Molecules packed together loosely that are free to move around one another
Ex: Ocean Wave
Gas: Molecules spread far apart that move around freely
Plasma: Ions spread far apart that move freely and quickly
What is matter made up…

1. What is the formula for Pressure? Pressure (P) =
2. What is the unit for pressure? The unit for Pressure is N/m2 OR pascal (Pa)
3. What is the formula for area? The formula for area is - Area = length x width
4. Summarize the paragraph on Pressure and the Particle Theory. Page 166
Particles are constantly moving in solids, liquids and gases.
Particles move quickly if they have a great deal of energy and move slowly if they have less energy.
When particles move there is a chance…
A cross-country move is not only a logistical nightmare, but it wreaks havoc on your nerves. By the time you get to your destination you're stressed out, confused, exhausted, and primed to make all kinds of stupid mistakes. Here’s what I learned after undertaking my own cross-country move.
We've walked you through a lot of the logistics of a move before, as well as how to settle down in a new city once you're there, so I won't retread too much into that territory again. However, after (mostly)…
