- Earth’s atmosphere is unique bc - rich in oxygen and nitrogen
- Continental shields are composed of? - very old and intensely deformed igneous and metamorphic rock
- Absence of folded mountain belts on Moon, Mars and Mercury is evidence that the crusts of these planets - are immobile and may have been so throughout each planet’s history

- PRACTICE QUIZ
- Ultimate source of energy for hydrologic system
- Most of water in hydrologic system is contain
- Island of Hawaii and volcanoes of Yellowstone are probably caused by
- Isostasy in recent geologic times can be measured by
- What time of plate boundary is shown in image from Japan?
- Ultimate source of energy for hydrologic system - solar energy
- Most of water in hydrologic system is contain - in the oceans
- Island of Hawaii and volcanoes of Yellowstone are probably caused by - a rising mantle plume
- Isostasy in recent geologic times can be measured by - all of the above (rebound of crust formally occupied by ancient lakes, subsidence of area surrounding large reservoirs, uplift of eroded mountains, rebound of the crust formally occupied by glaciers)
- What time of plate boundary is shown in image from Japan? - looks like trenches so should be convergent (honestly not sure - check again)
Ch. 8
Which principle below does NOT agree with the theory of catastrophism
- the ancient rock record was formed by the same processes at work today (true was that the earth is 6000 years old and supernatural forces were involved in the creation of the earth
Ch. 8

- how long it takes half of the parent isotope to decay to the daughter isotope
Ch. 8
The law of superposition suggests that the oldest rocks in a vertically-stacked succession of rocks should be
at the bottom
Ch. 8
A nonconformity is a special type of unconformity that places overlying sedimentary rocks in contact with
older metamorphic or igneous rocks
Ch. 8
The Precambrian Eon is distinctive from all others bc
- all of the above (there was little to no life present, preserved rocks from this time are almost all (if not all) metamorphic, they’re the oldest)
Ch. 8
Dinosaurs lived in the Cretaceous

Ch. 8
The law of cross-cutting relationships suggests that a granite dike in contact with another lithology is
younger than the surrounding rock
Ch. 3

Ch. 3
Cleavage in minerals refers to
- a tendency to break along planes of weakness
Ch. 3

- less variable than the color in hand sample among crystals
Ch. 3
Minerals are homogenous substances in that
- a minerals’ physical properties and geometry are spatially uniform (the material behaves much the same no matter where it is observed)
Ch. 3
