This diagram shows how body waves from and earthquake travel through the Earth. There are two types of body waves: P-waves and S-waves. Both types originate at the earthquake's epicenter. P-waves, or primary waves, travel faster than S-waves and are first to reach a seismometer. They can travel through solids, liquids, and gases, meaning they are able to penetrate the Earth's mantle, liquid outer core, and solid inner core. S-waves, or secondary waves, are about half as fast as P-waves and can only travel through solids. Therefore, they cannot penetrate the Earth's liquid outer core and only travel through the mantle. This creates a large section of the Earth at about 140 degrees away from the epicenter where there are no direct S-waves.

What explains all of these events? The answer can be summed up in one word: energy. Energy is defined as the ability to do work. Doing anything takes energy. A campfire obviously has energy. You can feel its heat and see its light.

Sound is a form of energy that travels in waves. Sound waves cant travel through empty space, but they can travel through gases. Gases in the air allow us to hear most of the sounds in our world. Because of air, you can hear birds singing, horns tooting, and friends laughing. Without the atmosphere, the world would be a silent, eerie place.

Scientists are a long way from being able to predict earthquakes. A good prediction must be detailed and accurate. Where will the earthquake occur? When will it occur? What will be the magnitude of the quake? With a good prediction authorities could get people to evacuate. An unnecessary evacuation is expensive and causes people not to believe authorities the next time an evacuation is ordered.

Electric current cannot travel through empty space. It needs a material through which to travel. However, when current travels through a material, the flowing electrons collide with particles of the material, and this creates resistance.

Minerals are made by natural processes, those that occur in or on Earth. A diamond created deep in Earths crust is a mineral, but a diamond made in a laboratory by humans is not. Be careful about buying a laboratory-made diamond for jewelry. It may look pretty, but its not a diamond and is not technically a mineral.

Crust, mantle, and core differ from each other in chemical composition. Its understandable that scientists know the most about the crust, and less about deeper layers (Figure 6.3). Earths crust is a thin, brittle outer shell. The crust is made of rock. This layer is thinner under the oceans and much thicker in mountain ranges.

Volcanoes erupt because mantle rock melts. This is the first stage in creating a volcano. Remember from the chapter Materials of Earths Crust that mantle may melt if temperature rises, pressure lowers, or water is added. Be sure to think about how and why melting occurs in the settings where there is volcanism mentioned in the next few concepts.

There are two major types of seismic waves. Body waves travel through the Earths interior. Surface waves travel along the ground surface. In an earthquake, body waves are responsible for sharp jolts. Surface waves are responsible for rolling motions that do most of the damage in an earthquake.

Earthquakes also occur at divergent plate boundaries. At mid-ocean ridges, these earthquakes tend to be small and shallow focus because the plates are thin, young, and hot. Earthquakes in the oceans are usually far from land, so they have little effect on peoples lives. On land, where continents are rifting apart, earthquakes are larger and stronger.

Freshwater below Earths surface is called groundwater. The water infiltrates, or seeps down into, the ground from the surface. How does this happen? And where does the water go?

Different parts of the Earth receive different amounts of solar radiation. Which part of the planet receives the most solar radiation? The Suns rays strike the surface most directly at the Equator. The difference in solar energy received at different latitudes drives atmospheric circulation.

Earthquakes also occur at divergent plate boundaries. At mid-ocean ridges, these earthquakes tend to be small and shallow focus because the plates are thin, young, and hot. Earthquakes in the oceans are usually far from land, so they have little effect on peoples lives. On land, where continents are rifting apart, earthquakes are larger and stronger.

Crust, mantle, and core differ from each other in chemical composition. Its understandable that scientists know the most about the crust, and less about deeper layers (Figure 6.3). Earths crust is a thin, brittle outer shell. The crust is made of rock. This layer is thinner under the oceans and much thicker in mountain ranges.

Intraplate earthquakes are the result of stresses caused by plate motions acting in solid slabs of lithosphere. The earthquakes take place along ancient faults or rift zones that have been weakened by activity that may have taken place hundreds of millions of years ago.

The theory of plate tectonics is the most important theory in much of earth science. Plate tectonics explains why much geological activity happens where it does, why many natural resources are found where they are, and can be used to determine what was happening long ago in Earths history. The theory of plate tectonics will be explored in detail in later concepts.

An earthquake is sudden ground movement caused by the sudden release of energy stored in rocks. Earthquakes happen when so much stress builds up in the rocks that the rocks rupture. The energy is transmitted by seismic waves. Earthquakes can be so small they go completely unnoticed, or so large that it can take years for a region to recover.
