Term
Who was Alfred Wegner?
Definition
He was the man who purposed the Continential Drift Theory. His theory purposed that the continents move or drift on an interior liquid layer. Similar to how ice floats on water. In 1915, he stated that all continents were all joined together in a land mass called "Pangea".
Term
What was the Theory of Plate Tectonics?
Definition
Earth is made up of 7 large plates and many small plates that are constantly moving.
Term
What is a Earthquake?
Definition
A sudden movement of the ground or a shake. This sometimes causes great destruction to the area that it occurs in.

What is Earthquake Energy?
Definition
It occurs in P and S waves. What causes these waves is a dramatic shift in the tectonic plates.
Term
How do you locate a earthquake?
Definition
P and S intervals are used to determine how far a earthquake has occured.

What is the Epicenter?
Definition
Place on the surface of the earth that is directly over the focus.
Term
What is the Focus?
Definition

The place where the earthquake is centered. Exactly under the Epicenter

 

Term
What is the Mercalli Scale?
Definition
Measures the effect of earths surface waves.
Term
What is the Richter Scale?
Definition
It measures the size or magnitude of the earthquake.
Term
What is a Earthquake Hazzard?
Definition
Fire,Aftershock,Tsunami,Flooding,Ground motion
Term
What is a Volcano?
Definition

Term
What is the Dew Point?
Definition
This is known as the temperature at which water vapor moleucules start to form liquids.
Term
What is High Pressure?
Definition
In hurricane developement, this is type of area that is formed when cold wind rises.
Term
What is Low Pressure?
Definition
This is the type of area that is formed when warm wind rises. This is the air pressure in the lower atmosphere
Term
What is a Stationary Front?
Definition
This type of front is when two air masses collide but one does not displace the other
Term
What is a Stratus Cloud?
Definition
This type of cloud are sheet-like and layered found at the Earth's surface
Term
What is a Cumulus Cloud?
Definition
These clouds are white and fluffy with flat bottom
Term
What is a Cirrus Cloud?
Definition

These clouds are thin and wispy,This cloud looks slender and weak.

 
Term

Term
What are the Thunderstorm Ingrediants?
Definition
The basic ingredients are the moisture, unstable atmosphere, and a "trigger"
Term
What is the Thunderstorm life stages?
Definition
developing stage, mature stage, and dissipating stage.
 
Term
What is the Squall Line?
Definition
A narrow band of high winds and storms
Term
What is a Tornado?
Definition
A tornado is a rapidly spinning tube of air that touches both the ground and a cloud above
Term
What is a Hurricane?
Definition
A storm with a violent wind, in particular a tropical cyclone in which winds blow down buildings and ocean waters destroy a local area
Term
What is a Saffir- Simpson Scale?
Definition
The Saffir- Simpson Hurricane Scale is a 1-5 rating based on the hurricane's present intensity
Term
What is a Surface Observation Symbol?

What is Kinetic Energy?
Definition
Kinetic Energy is energy in motion
Term
What is the formula for calculating kinetic energy?
Definition
Ke=1/2mv2
Term
What is Potential energy?
Definition
Potential Energy is stored Energy or energy that does not move

Term

What is chemical energy?

 

Definition
t is stored in the particles that make up food, fuel and other matter.
Term
What is mechanical energy?
Definition
This is is matter in motion.
Term
What is nuclear energy?
Definition
It is formed when tiny particles called atoms split apart (fission) or join together (fusion).
Term
What is electrical energy?
Definition
This is the movement of charged particles, negative (-) and positive (+).
Term
What is energy tranformation?
Definition
This is the process of changing one form of energy to another.
Term
What is the law of conservation of energy?
Definition
This is energy that can be neither created nor destroyed by ordinary means. It can only be converted from one form to another.
Term
What is a fossil fuel? What is the formation, source, and primary use?
Definition
The three different types of fossil fuels which are the primary uses are coal, oil, and natural gas. They were formed from prehistoric plants and animals that lived hundreds of millions of years ago. When the living things died, they decomposed and became buried under layers and layers of mud, rock, and sand.
Term
What is a electron?
Definition
These have a negative charge. This floats around the nucleus which is composed of protons and neutrons.
Term
What is Static Electricity?
Definition
A stationary electric charge, typically produced by friction, that causes sparks or crackling or the attraction of dust or hair.
Term
What is a static charge?
Definition
This is an electrical charge that is bound to an object. An unmoving electrical charge
Term
What is a coulomb?
Definition
This SI unit of electric charge, equal to the quantitiy of electricity conveyed in one second
Term
