Evidence & Observations
the way people interpret evidence is dependent on this critical thing
worldview
According to the old-Earth account in the chapter, how did planets form?
nebular hypothesis
Bonus points for explaining what that is
what is the explanation young-earth scientists give to explain the current location of continents?
What is the name of the idea that continents have moved over time?
continental drift theory
sea-floor spreading, which occurs around mid-ocean ridges, is driving by the movement of this
mantle
this refers to a geologic layer of rock
stratum (strata)
In the old-Earth account, what explains today's continent locations?
continental drift theory
movement of continents over millions of years
According to the young-Earth account, how many Ice Ages occurred?
one
Pangaea was the last of these, when all the dry land was in one spot
supercontinent
What does the old-Earth account say is needed for a glacial period to begin?
Gradual cooling of both continents and oceans.
Name one observation of the solar system used to discuss Earth's history.
Possible answers: planet composition and movement, gravitational pulls, or rotation directions.
Secular scientists use this model to talk about the layers of rocks over the millions of years
geologic column/time scale
how to young-earth scientists explain how fossils were formed?
Give one kind of evidence used to hypothesize that continents were once joined.
Matching climates, magnetic patterns, fossils, or similar minerals;
secular scientists believe this structure in our solar system formed after a collision
our moon
Name one observation about continents that is used to discuss Earth's past.
Possible answers: continents fit like puzzle pieces; matching magnetic patterns, fossils, or minerals; tectonic plates are moving.
According to the old-Earth account in the chapter, how many ice ages occurred over Earth's history?
many ice ages over billions of years (5+)
according to young-earth scientists, this layer of rock (or period of time) in the geologic time scale should have the greatest number and variety of fossils
the Flood
there are 15 of these that make up our earth's crust, continental and oceanic
tectonic plates
according to young-earth scientists, this is the lowest layer of the geologic column
Creation
this evidence in the rock layers can provide information about Earth's history and what creatures lived (and died) in each layer
fossils
According to secular scientists, why did ice ages start?
change in sun's output
wobble in orbit
less heat trapping in atmosphere
how many days did Noah and his family stay in the ark
371
who first developed and posited the theory of plate tectonics?
alfred wegener
Name kinds of evidence used to investigate Earth's history.
Possible answers: rock layers, fossils, magnetic patterns, continent positions, and evidence of past glaciers.
