1
These rocks provide evidence of plate movement because, as we look at rocks farther from the ridge, the rocks
have higher iron conent.
become thicker and thicker.
are made up of smaller particles.
are consistently older.
2
Which of the following processes is driven by the energy from Earth's interior?
Beach erosion
Melting of rock
Photosynthesis
Decomposition
3
The cycling of carbon between living/nonliving parts of the Earth system is important to what process?
Herbivores digesting plant material to get nutrients.
Methane entering the atmosphere from volcanic activity.
Condensation of water vapor leading to cloud formation.
Plants and animals exchanging gases with the atmosphere.
4
Energy from the Sun has an effect on the rocky surface of the Earth in which of the following processes?
Formation of crystals as molten rock cools.
Erosion of rock surface.
Faulting and folding of rock layers.
Landforms created by tectonic plate movement.
5
Which of the following surface features could be caused by moving ice, but not by moving water or wind?
Movement of sediments down the mountainside.
Carving out a canyon several kilometers long.
Transporting large boulders over many kilometers.
Smoothing and rounding rocks of different sizes.
6
Part of the recycling of seafloor material includes its destruction. This happens-
at trenches where rock material is subducted.
as a result of violent and frequent volcanic activity.
when elements in rock are rearranged chemically.
through weathering and erosion of exposed rock layers.
7
Which of the following provides evidence that the continents on tectonic plates have moved away from each other?
The frequency of volcanic activity is higher at edges of tectonic plates.
Fossils of same plants and animals are found on widely separated continents
The composition and thickness of rock layers varies at different depths.
Ocean currents can be disrupted near boundaries between tectonic plates.
8
Studying the distribution of 4 types of fossils it is determined that some plates traveled great distances. Evidence-
some fossilized organisms have only been found on one continent.
the oldest fossils, found in the deepest rock layers, represent ocean life
fossils of organisms that live in warm climates have been found in arctic.
species of organisms in the fossil record have changed over geologic time.
9
Which of the following changes to Earth's surface is most likely to represent the smallest scale of space and time?
A landslide on a mountain.
Breakdown of rocks into sediments.
Uplift of mountain ranges.
Formation of a canyon.
10
The distribution of which organisms can be used as evidence that Africa was once connected to South America?
Glossopteris, cynognathus, and mesosaurus.
Cynognathus, mesosaurus, lystrosaurus.
Cynognathus, glossopteris, and Lystrosaurus.
Lystrosaurus, mesosaurus, and glossopteris.
11
Which events would provide evidence of the greatest variation in the scale of time and space?
Earthquakes and landslides
Landslides and geochemical reactions
Delta formation and earthquakes
Geochemical reactions and delta formation
12
Which of the following provides evidence for past tectonic plate motions?
Matching fossils can show that land masses were once connected.
All of the above.
Glacial evidence has been found in areas where glaciers could not exist.
Matching rock type&rock formations can show how continents were attached.
13
New seafloor material is formed at places in Earth's crust where -
magma rises into the spaces where tectonic plates pull away from 1 another.
one tectonic plate slides beneath another and is forced downward.
lava flows from volcanic eruptions build up over many thousands of years.
rock is broken into pieces as tectonic plates push against one another.
14
Which of the following land features would take the longest amount of time to change?
Fractures in rock formations
Locations of continents
Shape of a volcano
Positions of sand dunes
15
Using only maps, scientists observed that -
the continents were all bordered by mountain ranges.
the oceans have become smaller throughout earth's history.
the shapes of the continents allowed them to fit together.
weathering and erosion have reshaped the surface of the earth.
16
When looking at the shape of the continental shelves that surround South America and Africa, they fit. This supports-
the continental shelves of these two continents are made of the same rock.
the tectonic plates beneath these continents are roughly the same age.
the material that makes up these continental shelves comes from sediments.
these continents were joined in the past and have moved apart in time.
17
A model of how material is cycled on the Earth would need to include all of the following EXCEPT-
Radiation from the Sun
Position and motion of the Earth.
Heat from the Earth's interior.
Movement of air, water, and rock.
18
What is an example of a change to Earth's surface that is usually gradual but is interrupted by a rapid event?
An earthquake resulting from tectonic plate movement.
The creation of sediments by breaking down rocks.
A flooding of wetlands caused by a hurricane's storm surge.
The formation of a delta at the mouth of a river.
19
What is responsible for the change in how scientists think about plate tectonics.
There are more people studying science now than in the past.
Tectonic plates have begun to move faster and faster over time.
New evidence was discovered that made scientists revise their ideas.
Scientists can now travel underneath the plates and observe their motion.
20
Which describes the most accurate way students can model how the Earth's surface is changed by a natural process?
Freezing different volumes of water to see when it will freeze.
Placing rocks in a container of water to see how the level of water rises
Heating water until it reaches the boiling point while measuring the temp.
Pouring water over sand in a container so it carried and deposited.
