Ogres Are Like Onions
Which of Earth's layers is the only one that is ACTUALLY a liquid?
The outer core.
Mr. Mandel will display an image. What type of plate boundary is shown?
A convergent plate boundary.
Describe one feature associated with volcanoes.
Answers will vary.
What does the Richter Scale measure?
The Richter Scale measures the strength/magnitude of an earthquake
What are two types of precipitation?
Rain, sleet, hail, snow, freezing rain, etc.
If you dove to the bottom of the ocean and touched the ocean floor, which of Earth's layers would you be touching?
The crust.
Mr. Mandel will display an image. What type of plate boundary is shown?
It is a divergent plate boundary.
Most of Earths volcanoes are found in a certain area surrounding the Pacific Ocean. What is this are called?
The Ring of Fire.
Mr. Mandel will display an image. What type of fault is shown? What type of stress causes this fault to occur?
It is a normal fault which is caused by tension (rocks pull apart).
Mr. Mandel will display an image. Which fossil is the youngest/newest?
The whale fossil is the youngest/newest.
Let's say a person were to travel from the crust to the core. What would happen to the heat and pressure they would experience as they traveled deeper into the Earth?
The heat they would experience would rise and the pressure would become greater the deeper they go.
Describe what happens at a transform plate boundary. What natural disaster is most common at this type of plate boundary?
Two plates slide past each other at transform boundaries. Earthquakes commonly occur at transform plate boundaries.
Mr. Mandel will display 2 images. What type of volcano is shown?
A shield volcano.
Mr. Mandel will display an image. What type of fault is shown? What type of stress causes this fault to occur?
It is a reverse fault caused by compression (rocks move together).
What is a fossil?
A fossil is the preserved remains of a living organism.
Molten rock in the mantle moves in a circular motion due to the heat from the core. What is this motion called?
Convection currents.
Convection currents in the mantle cause Earth's tectonic plates to move. Heat from the core causes the molten rock in the lower mantle to rise. When it reaches the crust it has nowhere to go so it begins to spread out. When it spreads out it cools and eventually falls back to the lower mantle.
Mr. Mandel will display 2 images. What type of volcano is shown?
A composite/stratovolcano.
Describe what happens before, during, and after an earthquake.
Before an earthquake occurs their is a build up of pressure between rocks at a fault line. When the pressure becomes too great the rocks suddenly and violently rip apart and release a large amount of energy. That energy is released as seismic waves that cause the ground to shake. The shaking can cause damage/destruction to natural and man made formations
What happens to water during the process of evaporation?
Water heats up (absorbs energy) and changes from a liquid to a gas.
The inner core is a solid because it experiences an extreme amount of pressure at all times. That pressure keeps the atoms of the inner core compacted tightly together.
What is subduction? What type of boundary does it occur at? Why does oceanic crust subduct beneath continental crust?
Subduction occurs at convergent plate boundaries where one plate is forced beneath another plate and sinks into the mantle. Oceanic crust is forced to subduct beneath continental crust because it is thinner and more dense.
What are the three classifications of volcanoes (based on activity)?
Active - volcanoes that are erupting currently or have erupted in the recent past and will likely erupt some time in the future.
Dormant - volcanoes that are not erupting, have not erupted in the recent past but still have a potential to erupt in the future.
Extinct - volcanoes that have not erupted in the recent past and do not have magma contained inside them. It is highly unlikely they will erupt ever again.
Describe how metamorphic rock could become an igneous rock.
If a metamorphic rock melts into magma or lava and then that magma or lava cools and hardens it will become an igneous rock
