The line that joins equal points of elevation.
What is a contour line?
The process that scientists believe is the driving force of plate movement.
What is convection?
The term that describes the process of spinning or turning on an axis?
What is rotation?
What are waxing and waning?
The term that describes all of space and everything in it?
What is the Universe?
The change in elevation between contour lines.
What is a contour interval?
The boundary where two plates slide past each other creating fault lines and earthquakes.
What is a transform boundary?
The term that describes the action of one object moving completely around another in an orbital path?
What is revolution?
What is a gibbous moon?
The three types of galaxy shapes in age order from oldest to youngest.
What are elliptical, spiral, and irregular?
The slope when contour lines are very close together.
What is steep?
The boundary that occurs when two plates come together to forms mountains and volcanoes and where crust is destroyed.
What is a convergent boundary?
This causes night and day on Earth.
What is rotation?
The phase of the moon where exactly 50% of the moon's reflected light is visible on its right side.
What the first quarter?
The Hertzsprung-Russell diagram compares these two qualities of stars.
What is luminosity/brightness and temperature/color?
Identified with an X or +, these are the only exact elevations listed on a topographic map.
What are the highest points?
The oldest crust is found at this point from a rift caused by a divergent boundary.
What is furthest away from the rift?
These two things cause the seasons on the Earth.
What are revolution and tilt?
The number of days a moon is in a crescent or gibbous phase.
What is six days?
This is why blue stars are hotter than red stars.
What is that blue has a shorter wavelength and gives off more energy, thus more heat.
The V-shapes on a contour map are caused by a river and point to this.
What is the source of the river.
The term that describes the process that occurs when one plate sinks beneath another plate at a convergent boundary because it is more dense.
What is subduction?
This is the season that occurs in the southern hemisphere when the north pole is pointed away from the sun.
What is summer?
The amount of time it takes to go from a New Moon to a Full Moon.
What is 14 days?
The age, color, classification, and two locations of our Sun.
What is a middle-aged, yellow, main sequence star at the center of our solar system located in one of the arms of the Milky Way galaxy?
