Geology 6 x 6 Earths’ Shifting Surface, pages 28-39

6 Vocabulary

1. Earthquake: shaking of the ground caused by the sudden movement of the rocks in the crust

2. Faults: A fracture in Earth’s crust along which rocks have moved. Most faults occur in groups called fault zones near plate boundaries

3. Shockwave: Waves of energy sent out when, for example, rocks are shifted beneath Earth by an earthquake

4. Plate margin: The meeting place of one plate to another

5. Volcanoes (list 4 kinds): Cinder cones are a volcano largely formed with rock fragments rather than lava, shield volcanoes are low, gently sloping volcanoes that are formed from lava that has solidified, lava dome volcanoes are formed by lava that doesn’t flow well and forms a cap over a volcanoes vent, stratovolcanoes are known as composite volcanoes because they are formed from layers of different materials

6. Mineral: substances found in nature, rocks are made from a lot of minerals

6 Sentences

1. An earthquake that happens under the sea triggers a tsunami because the tectonic plates keep moving after the earthquake.

2. The rate of movement along the San Andreas fault is around 2 inches a year; scientists predict that if this movement continues that San Francisco and Los Angeles will be next to each other around 15 million years from now.

3. A seismometer studies the shockwaves caused by an Earthquake.

4. There are four types of plate margin, destructive, collision, constructive, and conservative

5. The Ring of Fire is an area around the Pacific Ocean that is dotted with volcanoes; more than half of the world’s active volcanoes are found on the Ring of Fire, most of the earthquakes as well.

6. Suzy’s dad studies minerals, he is a mineralogist.  

6 Facts & Details

1. Preparation and responses to earthquakes is better than some countries than others. Countries that are developed and wealthy, such as the United States and Japan, cope quite well, poor countries such as Haiti, do not.

2. In some places, the magma heats water beneath the ground so it erupts in spectacular geysers

3. Scientists believe that the Volcanoes that are not close to the plate edges were formed by a hot spot under the plates

4. One of the reasons that communities have grown near volcanoes, is that volcanic soils are the most fertile in the world, this makes them idea for farming

5. Volcanic lava contains valuable minerals such as gold, zinc, and copper, they make an area near a volcano appealing to settlers

6. A caldera is a result of a massive eruption which then turns into an active volcano

6 Questions

1. Describe the Ring of Fire: the Ring of fire is a group of active volcanoes around the Pacific plate, this is where more than half of the world volcano eruptions happen, it also known for the being the most active place earthquakes

2. Can we predict earthquakes? A: Satellite imaging technology is so advanced now that it can detect movements in the crust of just a millimeter, this kind of satellite may one day be able to give advanced warnings of an earthquake  

3. Describe the 1906 San Francisco earthquake: this was a massive earthquake in San Francisco that killed about Seven Hundred people, and caused the whole city to be badly damaged, fires that took three days to bring under control caused even more damage, but the people repaired the city  

4. What is the epicenter of an earthquake? A: the epicenter is the center of the break of the tectonic plates

5. What happens when an earthquake occurs in the ocean? A: it triggers a tsunami

6. How long is the San Andres fault line and where is it located? A: The San Andreas fault is 680 miles long and it is located in California

6 Points of Interest Graphic Organizer: Classifying Web: Chemical Weathering  pg. 11

1. In chemical weathering, water, air, and acids cause chemical changes in the minerals of the rocks

2. Water dissolves the rock

3. Oxygen forms new compounds with minerals in rock, weakening the rock through oxidation when air touches the weathered rock

4. Acid gases in the air combine with rain to form acids, which break down faster than water

5. Water forms new compounds with the minerals in the rock, softening the rock

6. Some living things give off acid that breaks down the rock
