Origins of Earth
Scientists have proposed different explanations for how the solar system formed.
What hypothesis says the solar system formed from a large cloud of gas and dust?
Nebular hypothesis
A single layer of rock is called a
This frozen mass of ice can move across land and leave behind deposits and other features.
Glacier
This supercontinent is believed to have contained the continents before they separated.
Pangea
These large pieces of Earth's outer solid layer move slowly over Earth's surface.
Tectonic plates
In the Genesis account, creation is presented as occurring through God's creative work.
What Latin term means "from nothing"?
ex nihilo
The study of rock layers and their relationships is called
Stratigraphy
This process involves the wearing away and movement of sediment by agents such as water or ice.
Erosion
This scientist proposed the theory of continental displacement.
Alfred Wegener
The movement of plates away from each other can create this type of new crust.
Oceanic crust
This planet's unusual backward rotation is listed as a problem for the traditional secular explanation of Earth's formation.
Venus
This principle says that in an undisturbed sequence of rock layers, the oldest layer is normally at the bottom.
Superposition
In the diluvial geologic column, this event separates the Pre-Flood and Post-Flood eras.
The Flood
Matching examples of these preserved remains on different continents helped provide evidence that the continents were once connected.
Fossils
This underwater feature is where new oceanic crust commonly forms.
Mid-ocean ridge
This planet has an extreme tilt that is discussed as an unusual feature of our solar system.
Uranus
This type of dating uses radioactive elements to estimate the numerical age of rocks.
Radiometric dating
This animal, famous for its long tusks and thick fur, is used as an example when discussing extinction after the Ice Age.
Woolly mammoth
Matching these large landforms across continents provided another clue that the continents were once joined.
Mountain rangers
This process occurs when one tectonic plate sinks beneath another plate.
Subduction
According to the young-earth creationary view presented in this chapter, Earth's ultimate origin was...
Supernatural creation
Using the conclusion you are trying to prove as part of the evidence for that same conclusion is called
Circular reasoning
This level of the diluvial geologic column contains the greatest number and variety of fossils.
Flood event
Matching rocks, fossils, mountain ranges, and past climates across continents all provide evidence for this idea.
Continental movement
This process creates new ocean floor as magma rises at mid-ocean ridges.
Sea-floor spreading
