COFC Geology 105 Exam 1 John
Chadwick QUESTIONS AND ANSWERS
1. 4 most not unusual factors in planet - ANSWER-Fe, O, SI, Mg
2. Absolute relationship - ANSWER-Actual Years
3. Acasta Gneiss - ANSWER-oldest rock outcrop (four.03 BYO)
4. Accretion - ANSWER-developing of planetesimal by static energy, then gravity and
then colliding
5. Active Geology (Plate tectonics) - ANSWER-* Subduction
* Metamorphism Volcanoes
6. Aphelion - ANSWER-The farthest factor of the earth's orbit around the solar(July
4th)
7. Background radiation mapped at - ANSWER-2.7 ranges K is left from the Big Bang
8. Basalt - ANSWER-tiny iron oxide minerals (magnetite, spinel and ilmenite)
9. Chondrules - ANSWER-mainly silicate minerals, olivine and pyroxene, iron, nickel
10.Dark nebula - ANSWER-Clouds of hydrogen and helium fuel, dirt debris,
temperatures and strain is very low
11.Days have gotten 20 seconds longer inside the final million years because: - ANSWER-*
Tidal friction with the Moon
* We grow 3.8cm further away in step with yr
12.Differentiation - ANSWER-dense materials sink to company the center, lighter
materials form the mantle and crust
13.Earth rotates at Evidence for continental go with the flow: - ANSWER-* Continents
healthy together
14. * Fossils, glacial functions, and rock layer se- ANSWER-23.Five tiers
quences are now separated by using oceans
15.Half lifestyles: - ANSWER-* The amount of time it takes 1/2 of a collection of
radioactive parent atoms to decay to their daughter atoms
* Determined with the aid of how risky the nucleus is
* It is a stochastic (random) and immutable (unstoppable) system.
16.Harry Hess - ANSWER-Proposed the idea of seafloor spreading in 1962
17.How did the Solar System form? - ANSWER-* Pattern of motion (all planets orbit the
Sun inside the identical route, the planet's orbits are almost circular, and the sun
rotates within the equal path as the opposite planets)
* Inner vs Outer Planets: Compositional and length variations (Inner are small
rocky planets with excessive density, silicate mineral crust & mantles and iron
cores; Outer are large planets made normally of ices and fuel, small rocky and
meta cores with icy moons)
18.How far down are the outer and inner cores? - ANSWER-The outer center is 1800
miles down and the inner core is 1400 miles down; 800 miles in diameter
19.Isotopes - ANSWER-Same range of protons, one-of-a-kind number of neutrons
