Rocks and volcanoes
Answer: Metamorphic, Sedimentary, and Igneous
What are the three kinds of rocks?
Answer: this important part of plate tectonics occurs at mid-ocean ridges.
What is sea-floor spreading?
What is 3?
How many layers does the Earth have?
4
Answer: This tectonic plate is under most of the United States.
What is the North American Plate?
Answer: These two factors determine the thickness, or viscosity, of magma and lava.
What are temperature and silica content?
Answer: This is the location of many of Earth’s volcanoes and earthquake-prone areas called.
What is the Ring of Fire?
Answer: This is the cause of most earthquakes.
What does the movement of the earth’s crust, usually at plate boundaries, cause?
Answer: This layer is the hottest.
What is the inner core?
Answer: This tectonic plate is under YOU right now.
What is the Pacific plate?
What is it called when one kind of rock turns into another?
The rock cycle
Answer: These are the three types of plate boundaries.
What are “Convergent, divergent, strike-slip”
These massive geological formations are usually created at plate boundaries.
What are mountains?
Answer: This is the thickest of Earth’s layers.
Answer: YOU live near this kind of plate boundary.
What is strike-slip?
Answer: These volcanoes are generally small, but tall, with layers from many explosions.
What are cinder cones?
Answer: They are 3 types of evidence that exist for continental drift/plate tectonics.
What are fossils, mountain ranges, glacial deposits, and the shapes of the continents?
Answer: Seismometer
Question: What tool is used to detect and measure the strength of earthquakes?
Answer: These are the names of Earth’s three solid layers.
Crust, Mantle, Inner core (but the mantle can also act as a liquid over millions of years!)
Answer: This is the name of the nearest major fault to YOU!
What is the San Andreas fault?
Answer: These volcanoes are generally giant, but have gentle slopes.
What are shield volcanoes?
Answer: This type of energy transfer causes Earth’s plates to move
What is convection of the mantle and density differences?
Answer: The Richter Scale or the Moment Magnitude Scale
What scales are used to measure earthquake intensity?
Answer: This is the name of Earth’s liquid layer.
The outer core, but the mantle can also act as a liquid over millions of years!
True or False: YOU should run outside if an earthquake hits.
False! It is better to stay indoors under a table or desk if an earthquake hits, especially in CA, where the buildings are built to withstand strong earthquakes.
