The rock cycle
This kind of rock is formed when molten magma reaches Earth's surface and cools.
What is igneous?
This occurs at all plate boundaries when the tectonic plates shift.
What is an earthquake?
This is the number of stars in galaxies such as the Milky Way.
What is billions?
This is the coolest color of star.
What is red?
These are the main two forms of energy released by the sun.
What are light and heat (thermal)?
* If wind is said, keep trying!
This process can destroy mountains by slowly moving rocks and sediments away.
What is erosion?
The lithosphere is broken into these large pieces which can interact with each other to change Earth's surface.
What are plates?
This is the unit used to measure distances between stars or across galaxies.
What is a light year?
Stars produce energy from this process, which builds hydrogen and helium into larger elements.
What is nuclear fusion?
Because of its average temperature, the sun is classified as having this color.
What is yellow?
This process involves reactions with rocks, such as those caused by acid rain, breaking the rocks into smaller pieces.
What is chemical weathering?
The layer of Earth which is liquid due to its intense heat and generates Earth's magnetic field.
What is the OUTER core?
The shape of the milky way galaxy.
What is a spiral?
This property of stars takes into account how far from Earth the star is, and so measures its true luminosity.
What is absolute brightness?
Sunspots on the sun's surface are cooler patches caused by cooler gases sinking back through this process of heat transfer.
What is convection?
In the rock cycle, this kind of rock is often formed from sedimentary rock which is subjected to intense pressures in Earth's lithosphere.
What is metamorphic rock?
At plate boundaries, this process can lead to volcanic mountain formation as dense basalt is pulled under the lighter silcate rock.
What is subduction?
A large, rocky body orbiting the sun and surrounded by other, similar rock bodies is most likely this.
What is an asteroid?
The apparent magnitude of a star depends on these three factors.
What are distance from Earth, Temperature, and Size?
The dramatic release of matter and energy from the sun which loops back has this name.
What is a prominence?
Radioactive dating of igneous rock relies on measuring these, which decay overtime because of their instability.
What are (radioactive) isotopes?
The order, from inside to outside, of the Mesosphere, Lithosphere, Inner core, Outer core, and Asthenosphere.
What is Inner core, Outer core, Mesosphere, Asthenosphere, Lithosphere?
Parts of space which do not have galaxies in them are considered this.
What is void?
These are thought to be the largest stars in the universe, though not the most massive.
What are red supergiants?
This hot outermost layer of the sun's atmosphere can be seen during an eclipse and is sometimes thought of as a crown.
What is the corona?
