Earth Changes Pre- Review #2
ANSWERS POSTED ON BLOG
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 POSTED ON BLOG
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.
