This change is caused by solids that orbit the sun colliding with Earth. correct answers The cause
of impact change.
The era during which mammals diversified and thrived, primates, grasses, and hominins
developed, and Earth's climate transitioned from warm to cool. correct answers Cenozoic
Features such as near-instantaneous changes in climate, biological diversity, & the composition
of the oceans and atmosphere. correct answers Earth feature(s) caused by impact change
A tectonic configuration in which most landmasses are connected. correct answers
Supercontinents
An area at Earth's surface where large quantities of magma erupt. correct answers Volcanic
Province
The era during which mammals, dinosaurs, flying & swimming reptiles, & flowering plants first
developed. During this time, dinosaurs, insects, & flowering plants flourished, and Earth's
climate was mostly warm. correct answers Mesozoic
This change is caused by the slow flow (convection) of solid rock in Earth's mantle. correct
answers The cause(s) of tectonic change
The eon in which single-celled life thrived, modern plate tectonics developed, oxygen levels in
Earth's atmosphere rose to roughly modern levels, and the first complex life forms emerged.
correct answers Precambrian
A sudden and violent shaking of the ground that results from movements within Earth's crust.
correct answers Earthquake
A large band of Earth's crust that has been uplifted by tectonic activity. correct answers
Mountain Belt
The era in which Earth had a modern atmosphere and abundant complex life first flourished.
correct answers Paleozoic
Features such as eroding highlands, streams & glaciers (which move sediment), and sediment-
filled basins. correct answers Earth feature(s) caused by surface change
This change is caused by altering the concentration of atmospheric greenhouse gases (mostly
carbon dioxide), as carbon moves between the atmosphere and solid Earth. correct answers The
cause of climate change.
Features such as the appearance of new species (speciation), demise of species (extinction), &
composition of Earth's atmosphere. correct answers Earth feature(s) caused by biological change
,Features such as average global temperature, long-term average weather, types of organisms that
can thrive or survive, & average weathering rate. correct answers Earth feature(s) caused by
climate change
Weathering & erosion expose fresh rock. correct answers True
When solids orbiting the Sun collide with Earth, they can drastically alter climate conditions and
the development of life. correct answers True
Climate change commonly produces large mountain ranges. correct answers False
During the Cenozoic, Earth cooled & mammals dominated terrestrial landscapes. correct answers
True
Volcanoes result primarily from the slow flow of rock in Earth's core. correct answers False
In the past, sea level has been much higher than it is today. correct answers True
Most volcanic areas have been active through most of Earth's history correct answers False
Single-celled organisms such as cyanobacteria were the only inhabitants of Earth during the
Paleozoic. correct answers False
Once mountain ranges form, they last essentially forever. correct answers False
The Paleozoic is the era in which Earth formed. correct answers False
There has never been a period in Earth's history in which large impacts were commonplace.
correct answers False
During the Mesozoic, Earth's climate was mostly hot and dinosaurs ruled terrestrial landscapes.
correct answers True
Low density crust produces ocean basins, and high density crust produces continents. correct
answers False
Biological change can cause climate change. correct answers True
The Mesozoic era came before the Paleozoic era. correct answers False
This change is caused by the slow flow (convection) of solid rock in Earth's mantle. correct
answers The cause(s) of tectonic change
Features such as the appearance of new species (speciation), demise of species (extinction), &
composition of Earth's atmosphere. correct answers Earth feature(s) caused by biological change
, The part of Earth's crust made of less dense rock that lies mostly above sea level. correct answers
Continents
Features such as average global temperature, long-term average weather, types of organisms that
can thrive or survive, & average weathering rate. correct answers Earth feature(s) caused by
climate change
Features such as eroding highlands, streams & glaciers (which move sediment), and sediment-
filled basins. correct answers Earth feature(s) caused by surface change
Sedimentary rocks are excellent records of Earth's surface processes and conditions. correct
answers True
The structure of Earth materials is used primarily to determine the source(s) of those materials
(that is, where those materials came from). correct answers False
Metamorphic rocks are superb records of the formation and evolution of mountain belts such as
the Appalachian Mountains belt. correct answers True
Ideas that allow humanity to systematically determine the historical sequence of events for Earth.
correct answers The principles of relative dating
These features record the nature of Earth's surface at the time they formed (for example, a beach
in one location and a coastal plain in another, etc). correct answers Origin implications of
sedimentary rocks
These features record how mountain belts and continental crust form and develop (for example,
how the Appalachian Mountains formed and evolved). correct answers Origin implications of
metamorphic rocks
The principle of fossil succession states that fossils found in sedimentary rocks form a consistent
pattern that can be used to correlate sedimentary layers across significant distances. correct
answers True
Metamorphic rocks are superb records of Earth's surface processes and conditions. correct
answers False
These features indicate that tectonic processes produced magma (for example, melting in a
mantle plume) that moved into or through the crust (for example, as has happened near BYU-
Idaho and in Yellowstone & Hawaii). correct answers Origin implications of igneous rocks
This change is caused by shifts in the characteristics of populations as they adapt to a changing
environment. correct answers The cause of biologic change
