The following are the essential questions that drove the knowledge, understanding, and application of activities within the Earth Science unit. Respond to each question in your entry.
1-How do scientists support observations that the Earth has three interior layers (crust, mantle, core)?
2-Why do we know that continents once were all connected together in a single land mass called Pangaea? What evidence supports Pangaea?
3-What changes have occurred to Earth over time and how do these changes impact today, tomorrow, and the future?

Earth Changes Pre- Review #2
ANSWERS
1. State Alfred Wegener’s hypothesis about how the Earth’s continents have moved.
ALL CONTINENTS ONCE WERE JOINED TOGETHER AS PANGEA, BUT HAVE SINCE DRIFTED APART.
2. Name the three pieces of evidence Wegener used to support his hypothesis. 1.CLIMATE 2. FOSSILS 3. LANDFORMS
3. PLATES carry the pieces of the Earth surface include oceanic and continental crust.
4. True or False- The theory of plate tectonics explains that plates are in constant motion because of the convection currents in the mantle.
TRUE
5. Describe the movement of the plate boundaries below
Divergent boundary-TWO BOUNDARIES MOVE AWAY FROM EACH OTHER
Convergent boundary-TWO BOUNDARIES MOVE TOWARDS EACH OTHER
Transform boundary-TWO BOUNDARIES PASS EACH OTHER IN OPPOSITE DIRECTIONS
6. True or False- Earthquakes can occur at plate boundaries and fault lines.
TRUE
7. What was the supercontinent called 225 million years ago?
PANGEA
Earth Changes Pre- Review #3
ANSWERS
1. Scientist know about the interior of the Earth due to SEISMIC waves that release energy during an earthquake.
2. Rocks change shape and volume after an earthquake as tension, compression, and shearing takes place. This is know as STRESS.
3. An earthquake occurs deep within the interior of the Earth at this point,FOCUS. Energy is release and travels to the EPICENTER, which is directly above the point within the Earth’s interior.
4. Energy travels to create an earthquake within three different seismic waves. Name the waves and describe its energy movement.
P WAVE- COMPRESS AND EXPANDS GROUND WHERE ENERGY IS RELEASED- WE DO NOT FEEL
S WAVE- LEFT RIGHT AND UP AND DOWN MOVEMENT WHERE ENERGY IS RELEASED- WE DO NOT FEEL
SURFACE WAVES- COMBINATION OF P AND S WAVES WE FEEL AS ENERGY IS TRANSFERRED TO EPICENTER
5. The RICHTER scale records the size of the seismic waves through the use of a SEISMOGRAPH that is buried within the continental or oceanic crust. The scale record the release of the energy from 0-9, which is called the MAGNITUDE of the earthquake.
6. A volcano is a weak uplifted spot within the crust that has melted material called MAGMA and once this reaches the surface it is called LAVA turning into solid rock.
7. Almost all earthquakes and volcanoes occur at (circle the correct answer). A IS THE CORRECT ANSWER
a. faults, plate boundaries, Ring of Fire
b- faults and plate boundaries
c- Ring of Fire and breaks in the mantle
8. Describe the three types of volcanoes
SHIELD VOLCANO= WIDE SLOPING MOUNTAINS
Cinder Cone = STEEP CONE SHAPED HILL OR MOUNTAIN
COMPOSITE VOLCANO=TALL CONE SHAPED MOUNTAIN WITH LAYERS OF ASH AND LAVA
Caldera= volcano that can collapse due to magma emptying.
9. The type rocks that form from magma include BASALT and PUMICE (that can float).
10. Rocks are classified into three groups
1.SEDIMENTARY
2.IGNEOUS
3.METAMORPHIC
11. What does it mean to classify in science (think back to process skills).
GROUP ROCKS BASED ON OBSERVED CHARACTERISTICS AND TRAITS THAT ARE SIMILAR.
Supervolcano
Movie developed by the Discovery Channel
Supervolcano connects to the Earth Changes unit.
Summary- USGS scientists and researchers that work at Yellowstone collect data and use Vergil (prototype of Yellowstone) that predicts a VEI 8 eruption in the near future. The USGS scientists takes steps to inform the public, but the government does not want to cause chaos in the country. Unfortunately, the caldera under Yellowstone erupts causing a VEI 8, and USGS along with the government have to work together to handle this natural disaster today, tomorrow, and in the future.
During and after watching this movie, students will be able to:
1. Determine the cause and effect relationships during a VEI 8 volcanic eruption.
2. Identify the predictions and hypotheses that lead up to a VEI 8 volcanic eruption.
3. Evaluate the government and scientists plans for the evacuation and aftermath from the volcanic eruption.
4. Recount scientific Earth changes concepts such as: lava, magma, seismograph, Richter Scale, caldera, lava flow, pyroclastic flow.
5. Analyze from the scientific predictions and data if a Supervolcano eruption will occur at Yellowstone in the near future.
