MEA 101 EXAM 1 QUESTIONS AND ANSWERS NEWEST
RATED A+ 2025/2026
What is a scientific theory? - Ans One of the most reliable forms of scientific explanation
Horizontal strata (layers) extend laterally until
they thin to zero thickness (pinch out) at the
edge of their basin of deposition. - Ans Law
Changes in the Earth's crust during
geological history have resulted from the
action of continuous and uniform processes
that we can observe today. - Ans Theory
The Younger Dryas cold period 12,000 years
ago was caused by a meteorite impact. - Ans Hypothesis
The structure of the Earth's crust results from
the interaction of rigid lithosphere pieces that
moves slowly over the underlying mantle. - Ans Theory
Sediment that is deposited into a basin
will form sedimentary layers that are
initially deposited horizontally. - Ans Law
What was Alfred Wegener's main hypothesis? - Ans Earth's landmasses used to form a single
supercontinent (Pangea)
, Which observations did Wegener NOT use to support his continental
drift hypothesis? - Ans . Patterns of earthquake locations within ocean
basins
A scientific hypothesis offers a well-defined natural cause to explain a
natural phenomenon. At the time, Wegner's hypothesis was not widely
accepted. Why not? - Ans Because he couldn't offer an explanation of how the
continents could have moved
What defines the earth's insides? - Ans Thin crust, big core
What is the lithosphere? - Ans crust and upper mantle
As you move from a continent toward a mid-ocean ridge
from either side, the age of the seafloor crust gets
and the thickness of the overlying sediment
gets . - Ans Younger; Thinner
Divergent plate boundaries are typically characterized by - Ans oceanic ridges
Earthquakes are associated with divergent plate boundaries - Ans True
Volcanoes are associated with convergent plate boundaries - Ans True
Most of the world's active volcanoes are found along divergent plate boundaries - Ans False
