Parts of Earth
Name the four layers of the Earth, in order from center to outer layer.
Inner Core, Outer Core, Mantle, Crust
How do mountains form?
Mountains form from the collision of two continental plates
Which planet is the biggest in our solar system?
Jupiter
How do igneous rocks form?
Igneous rocks form when hot, molten rock crystallizes and solidifies.
What is the difference between the asthenosphere and the lithosphere?
The lithosphere is the strong, upper 100 km of the Earth. The lithosphere is the tectonic plate we talk about in plate tectonics.
The asthenosphere is the weak and easily deformed layer of the Earth that acts as a “lubricant” for the tectonic plates to slide over.
How do volcanoes form?
How many moons does Mars have?
2 moons
How do sedimentary rocks form?
Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock
How has plate tectonics changed the way the earth looks?
Earthquakes, mountains, volcanoes, Pangea has become multiple continents.
What is the Ring of Fire?
A long horseshoe-shaped seismically active belt of earthquake epicentres, volcanoes, and tectonic plate boundaries that fringes the Pacific basin, located in the Philippines.
Inner planets are made of rock (solid), outer planets are gas planets.
How do metamorphic rocks form?
Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or a combination of all of these.
Why do scientists believe that the inner core is solid?
When waves pass through the core, they become shear waves, which can only exist in solid material.
What causes earthquakes?
Friction between tectonic plates.
What is the name of the first spacecraft to cross the heliosphere?
Voyager 1
What is the name of the fault line located in San Francisco?
The San Andreas Fault Line
