breakup of a moon occurs within about 2.44 planetary radii of its host planet
What is the Roche limit?
This theory has issues because it doesn't explain how a ring or debris would form the moon, the Roche limit, or the low probability of celestial objects colliding
What is the collision theory?
Due to tidal effects, the moon is spiraling this direction in relationship to earth
What is outward?
This isotope is limited to a much shorter time scale than other isotopes
What is carbon-14?
This allows for a continuously growing layer or dust on the moon
What is lack of weather elements?
The time it takes for the moon to make a complete revolution around earth
What is 27 days?
The speed at which the earth's and moon's equators move in miles per hour
What is 1000 miles per hour and 10 miles per hour?
The first day of spring, around March 20-22
What is the vernal equinox?
This theory says a chance collision occurred billions of years ago when an object the size of Mars hit the earth, partially melting both and throwing debris
What is the collision theory?
These power stations use the rise and fall of water to spin turbines similar to the ones at hydroelectric dams
What are tidal power stations?
The age of the moon according to secular scientists
What is 4.6 billion years?
This word is used to describe the rate of dust fall on the moon
What is influx?
To reconcile the difference between the lunar year of 354 days and the year of seasons having 365.25, this calendar adds a 13th month
What is the lunar calendar?
This characteristic of the moon's surface allows it to reflect light equally in all directions
What is its roughness?
The name given to the average reflectivity of the moon
What is the albedo?
This theory says a wandering moon passed too close to earth and it was captured in the earth's gravitation (doesn't really explain the origin of the moon if it arrived intact)
What is the capture theory?
This limit indicates that because the moon moves one to two inches away from earth each year, it would have already broken up if formed billions of years ago
What is the Roche limit?
The method used to calculate the secular age of the moon
What is radioisotope studies of moon rocks and meteorites?
The reason the astronaut footprints are still on the moon
What is lack of wind or liquids?
These predictable events allow there to be a lunar calendar
What are motions, phases, and eclipses?
The moon's gravity attracts many rocks protecting us from this
What are space collisions?
A growth of the earth and its moon from dust and gas occurring side by side in space
What is accretion?
This theory was championed by one of Charles Darwin's sons. It says the earth was once molten and spinning rapidly, a growing tidal bulge was occurring because of the sun that was eventually thrown or fissioned from the earth to form the moon
What is the fission theory?
Color changes, glowing clouds, streaks of light, and measurable seismic activity are examples of this
What are TLPs?
An excess of this causes certain kinds of atoms to be unstable or radioactive
What are neutrons?
Extensive weathering on a short time scale in moon craters is evidenced by this
What is debris, avalanches, and cave-ins?
The moon does this to help make seasons less severe and more predictable
What is stabilize the earth's tilt angle?
These assumptions are made when using radioisotope dating
What are the original composition of the sample and not knowing what changes may occurred over the history of the sample?
from no previously existing matter (literally, out of nothing)
What is ex nihilo?
Explain the three popular older theories about the moon's origin
Fission or splitting off of material from earth; capture of an external moon by the earth's gravity; condensation of nebulous gas and dust at the same time
These 3 lunar craters have been sites of numerous TLPs
What are Aristarchus, Plato, and Alphonsus?
The half life of Carbon-14 and Uranium-235
What is Carbon-14=5,730 years and Uranium-235=0.704 billion years?
This reaction occurred when the Apollo 12 landed on the moon
What is the vibration of the moon for 55 minutes?
The cell structure modification necessary for salmon to transition between fresh and saltwater occurs during this phase of the moon
What is new moon or thin crescent?
These are the 4 solid biblical arguments for creation
What are yom, evening and morning, clear designation of work and rest days, linking of word "days" with the word "years"?
