What are the significant layes of the Geologic column?
Jurassic
Triassic
Cambrian
Pre-Cambrian
What is the origin of the Grand Canyon?
inland sea pushed out sediment
the flood
According to creationist how many stages did it take to form the Grand Canyon where is the evidence
2
What are the points of entry into the Grand Canyon and which one is best for hiking to the river and why?
North & South Rim
South because it is 1000 ft lower
What is the width length and depth of the Grand Canyon
Width- 5 miles
Length- 216 miles
Depth- 1 miles
Length of Mid-Oceanic Ridge
46000 miles
Directionality of North American Plates and EuroAsian Plates
west
east
pacific
Collision of plates & consequences
Ring of Fire
Earthquakes
Volcanoes
Continental drift vs sprint
started sprinting now its drifting
Hydroplate vs traditional geological tectonic plates
water under plates vs magma
Submarine Canyons- What and where are they?
gourdges
mouth of hudson and amazon rivers into the ocean
When could they have originated (Submarine Canyons)
high altitude and low water lines
Two potential reasons why they are so deep.
Volume vs Depth
oceans getting lower, plates are rising and water runs off
Coal & Oil Formations
Found in unlikely places why?
artic & antartica
Coal & Oil Formations
What could be inferred as to their presence?
because very little life is there trees that are 100 ft tall
the earth was warmer before the flood
Methane Hydrates:
What is the origin today of Methane?
2000 feet deep
Methane Hydrates:
When and how can methane be stored
dry ice
Methane Hydrates:
Where are these hydrates found today?
Oregon off the coast
Methane Hydrates:
What is the potential benefit of mining methane hydrates?
cheap fuel
How could the Ice Age be initiated
high land accumulation of show
alot of volcanic activity
What two ingredients are needed for ice to accumulate?
warm water
high altitude
What is the bottom layer of the Grand Canyon and what is supposed to be its index fossil
PreCambrian
Trilabite
What is the next layer up and what is the significance of its name
Cambrian-Plant is what it means
What is the layer where dinosaurs were supposed to die out?
Jurassic
How many total layers are in the Geologic Time Column
13
What is the evidence in the Grand Canyon points to the presence of a once shallow inland sea
