3rd/Last Quarter
What phase occurs during position 7?
Transform
Boundary in which plates are sliding past each other and create faults.
Waning
A moon phase in which the moon's illumination is decreasing every day; locations 6,7 and 8 in diagram
Divergent
Boundary in which plates separate and create mid-ocean ridges and rift valleys
Axis
Earth rotates around this and is tilted
Full Moon
Which phase occurs between position 3 and 4?
Steep
Contour lines that are close on a topographic map indicate a _____________ slope.
Neap tide
What tide occurs during the phases in position 1 and 3 of the diagram?
Spring tide
What tide occurs during the phases in position 2 and 4 of the diagram?
Topographic map
Shows the elevation of land forms with contour lines
Rotation
Is responsible for day and night
Revolution
Is responsible for the year
Crescent
A moon phase in which less than half of the moon is illuminated; Locations 2 and 8 in diagram
New Moon
Which phase occurs between position 2?
Convergent
Boundary in which plates move toward each other and create folded mountains or volcanic mountains at subduction zones
Mountains
Land forms created by convergent boundaries
1st Quarter
What phase occurs at position 3?
Light-Year
Is used to measure distance between stars and galaxies
Tilt
This is responsible for the seasons on Earth
Weathering
The physical and chemical break down of land due to wind, water, ice or chemicals
Earthquakes
Can occur at plate boundaries especially at transform boundaries
Waxing
A moon phase in which the moon's illumination is decreasing every day; locations 2,3 and 4 in diagram
Fault
Occurs at transform boundaries
Mid-Ocean Ridge
Land form created by divergent boundaries
Contour lines
Found on a topographic map that indicate elevation
