A natural satellite of Earth.
What is the moon?
This explains why seasons occur.
What is Earth's tilt on its axis?
Large solid, brittle pieces of rock composed of the crust and upper mantle.
What are lithospheric plates?
Energy released from this spot starts an earthquake.
What is the focus?
This type of volcano is found along convergent subduction boundaries.
What is a composite volcano.
The phase of the moon occurring approximately two weeks after the new moon.
What is the full moon?
The shortest day of the year in the northern hemisphere.
What is the winter solstice?
This process causes the lithispheric plates to move towards, away from, or next to each other.
What is mantle convection?
This area is the point on Earth's surface where the earthquake is first experienced.
What is the epicenter?
This type of volcano is small but explosive.
What is a cinder cone?
The term used to describe a lunar phase when it is between the full moon phase and the new moon phase.
What is waning?
During this 24- our period, the length of a day is equal to the length of the night.
What is the equinox?
The Himalayas are the result of this boundary type.
What is a continental-continental convergent boundary or a collision boundary?
This seismic body wave does not travel through liquids.
What is an S-wave?
The low viscosity lava that makes up this volcano gives it a gentle slope.
What is a shield volcano?
This tidal phase occurs during a new moon phase.
What is Spring tide?
During this season the hours of daylight go from being equal to night to being shorter and shorter each day.
What is fall?
A volcanic island arc forms at this boundary type.
What is a oceanic-oceanic convergent boundary?
This number of seismic stations is required in order to locate the epicenter of an earthquake.
What is three?
This magma type is highest in silica, dissolved gas content, and highest in viscosity.
What is rhyolitic magma?
A rare celestial event visible only to those in a narrow belt.
What is a solar eclipse?
On this day the midnight sun occurs in the northern hemisphere.
What is the summer solstice.
This principle is supported by both the age of rocks on the ocean floor as well as symmetrical paleomagnetic patterns discovered on the ocean floor.
What is seafloor spreading?
This term is used to describe the amount of energy released by an earthquake.
What is magnitude?
The andesitic composition of this volcano type results in a volcano with sometimes explosive, sometimes effusive eruptions.
What is a composite volcano?
