physical and chemical process, transforms sediments into sedimentary rocks
What is lithification?
100
a proposed explanation
What is a hypothesis?
100
light waves appear longer when stars are moving away from Earth, creating longer wavelengths
What is a red shift?
100
for every action, there is an opposite and equal reaction
What is Newton's Third Law?
100
mission that found that hot radiation spots=matter formations,cold spots=empty space. Universe is 13.7 billion years old
What is WMAP?
200
an intrusion or fault is younger than any rock it cuts across
What is cross-cutting relationships?
200
deepest part of the ocean basin
What is a trench?
200
continuous color with black lines, only some wavelengths or energy emitted.
What is the absorption spectrum?
200
an object in motion will stay in motion, and an object at rest will stay at rest, unless acted upon by an outside, unbalanced force
What is Newton's First Law?
200
occurs when the rock layers involved are both sedimentary
What is a disconformity?
300
the action of surface processes that remove soil, rock, or dissolved material from one location on the Earth's crust, then transport it away to another location
What is erosion?
300
new oceanic crust forms along a mid-ocean ridge and older oceanic crust moves away from the ridge
What is seafloor spreading?
300
the intense heat and pressure force electrons to combine with protons, forming neutrons. 1 tsp. = weight of the moon
What is a neutron star?
300
the more force applied to an object, the more it will be accelerated, and thus the more it will change its motion
What is Newton's Second Law?
300
hydrogen in the core is used up, fusion stops and the core collapses due to gravity
What is a red giant?
400
occurs when sedimentary rocks overlie non-sedimentary rock layers
What is a nonconformity?
400
the only totally liquid layer in Earth's interior
What is the outer core?
400
used to describe the expansion of the universe. Found that the farther galaxies are from Earth, the faster they are moving.
What is Hubble's constant?
400
rate of change of velocity
What is acceleration?
400
a blurry picture, but it showed that CMB radiation temperatures vary
What is COBE?
500
meteor impacts, magnetic polarity reversal and volcanic ash layers
What are key beds?
500
very explosive volcanoes that are made of alternating layers of solids and lava
What is a composite volcano?
500
an organized chart of wavelengths and frequencies over which electromagnetic radiation extends
What is the electromagnetic spectrum?
500
the tendency of an object to resist any change in its motion
What is inertia?
500
the process in which mineral growth binds sediment grains together into solid rock
