Unlike the famous candy bar, earth's galaxy was given this name because it's spiral arms create a milky-colored band in the sky.

Matching fossils and the continental puzzle are just 2 evidences for this man's theory of continental drift
What is Wegener

This type of wave is not as fast as some and only travels through solids
What is s waves
100
A broad, large volcano of this type forms from quiet eruptions of fluid lava
What is shield volcano
100
Obsidian and pumice rocks form from lava that cools very quickly, becoming this type of rock
What is extrusive igenous

Much like the motion of a top, the Earth's rotation is changing direction every 26,000 years during this process
What is precession
200
This part of the earth, composed of crust and upper mantle, is broken into plates that move with respect to one another
What is lithosphere
200
If you live in a house in this location, you are directly over the focus and will experience the most violent shaking
What is epicenter
200
Lava that is crunchy and jagged is this type and will also make you say this when you step on it barefooted
What is a'a

All rocks are classified for how they
What is form

When the moon and sun form a right angle with earth in the middle, this moon phase is occurring.
What is quarter moon
300
Movement of heat from earth's core travels through the asthenosphere and moves the plates during this process
What is mantle convection
300
These waves cause severe shaking and are the most damaging of the entire earthquake
What is surface waves

Pompeii was covered in ash as Mt. Vesuvius, a stratovolcano erupted releasing this type of material

Seafloor spreading and ocean ridges are forms where convection currents are rising, at this boundary type
What is divergent
400
When a seismologist analyzes and earthquakes p and s wave arrival times, they can use that information to determine this factor about the earthquake
What is distance
400
Magma with high viscosity, high gas content and cooler would lead to this type of eruption
What is violent/explosive
400
The rock type that can have fossils is
What is sedimentary

Shorter ones of these are filtered out before reaching earth, thankfully
What is wavelengths
500
Anytime an oceanic plate converges with any other plate, this process occurs and always produces volcanoes
What is subduction
500
The majority of earthquakes and volcanic zones exist here in this location, located on the perimeter of one of earth's largest plate boundaries
What is the Pacific ring of fire
500
Lava that is slow moving resembles a persons movements when they "feel sick"
What is felsic
500
Metamorphic and Igneous rock both form from the same source of heat that drives this process
What is plate tectonics
