3) How does the temperature of the Earth’s mantle compare to the other layers of the Earth?
The mantle is hotter than the core.
The mantle is hotter than the crust.
The mantle is the same temperature as the core.
The mantle is the same temperature as the crust.
How does the density of the Earth’s core compare to the other layers of the Earth?
The core is the densest layer.
The core is the least dense layer.
The core is only less dense than the crust.
The core is only less dense than the mantle.
Clear-cut logging is a method of cutting down all the trees in a particular area. This type of logging is MOST LIKEY going to effect which earth process?
erosion
climate
weathering
mountain building
What geological forces might be responsible for this range of mountains?
diverging tectonic plates
converging tectonic plates
erosion of the land by the ocean
deposition of sediments by the ocean
A group of students on a field trip found loose rock and gravel at the foot of a rocky cliff. These rocks were of the same material as the rocks on the cliff. The students know that the place has a cold and wet climate. On the basis of this evidence, what could be a possible explanation for the presence of the loose rock and gravel at the foot of the cliff?
The rocks might have broken off due to alternating cycles of freezing and thawing of water.
Acid rain could have caused chemical weathering, resulting in the breaking of chunks of rock.
Oxygen in the air could have reacted with the minerals in the rock, causing the rusting of the rocks.
The rocks were probably always there. Weathering cannot be the cause, because it possible only in warm and wet conditions.
Signs like this appear all over coastal regions. Why?
The grass holds moisture in the ground.
The grass provides shelter for many animals.
The grass helps to keep the sand dunes in place.
The grass helps to keep the air temperature constant.
A large canyon, with a large river running through the bottom, was MOST LIKELY formed by
erosion.
a volcano.
a hurricane.
an earthquake.
The North Carolina landmass formed about 1.7 billion years ago and has been in constant change ever since. Continents broke apart, merged, and then drifted apart again. As land movement occurred, ___________________ to form the Appalachian Mountains.
landmasses split
earthquakes occurred
volcanoes emerged
landmasses came together
A landslides is natural hazard usually related to the instability of a slope. Human activities can directly influence the occurrence of landslides. All but one would be considered a human cause. That is:
mining
excavation
weathering
deforestation
As water flows out of the stream's channel, it immediately slows down. The material carried by the stream, sediment such as gravel, sand, silt, and clay, is deposited on the floodplain. Large particles are deposited first, and much of this material is laid down alongside both banks. This process, repeated over and over, forms low ridges or mounds known as natural levees. As flooding continues, sediments are lifted over the levees and deposited as noted in the photograph. These areas often the sites of farming because the sediments deposited tends to be very fertile.
Floodwaters bring fine silt-like sediments over the levees. Why does the water tend to carry such particles rather than sand or gravel?
During a storm, a river is carrying a lot more sediment than during a low-flow period.
The waters that pass over the levees are moving very slowly and can only carry light, fine particles.
Fast-moving water can pick up, suspend, and move larger particles more easily than slow-moving waters.
The fast-moving flood waters that rise over the levees tend to carry massive amounts of heavily compacted silt sediments.
Scientists have used the distribution of fossils and rocks, continental shapes, and seafloor structures as evidence of past plate motions. Alfred Wegener, a German geophysicist, proposed the theory of continental drift based on his studies of similar fossils and rock strata across continents. Wegener found a mountain range ending at South Africa's coast seemed to align with the edge of a range in Argentina, forming a continuous belt. This map displays similarities in fossils found on continents based on Wegener's theory.
Which statement provides additional evidence supporting the scientific conclusion that continents were once joined, but have drifted apart over time?
Similar plants alive today are found in Africa, North America, South America, and Asia, and migratory birds of these continents have similar migration patterns.
When comparing climates around the globe, areas near the Equator tend to have similar patterns, as do areas near the North and South Poles, and within latitudinal bands.
The sequence of rock layers on Africa's western coast is almost identical to the sequence found on South America's eastern coast, including layers containing similar fossils.
Most glaciers found around the North Pole have edges that seem to align with glaciers at the South Pole; evidence of continental drift between Antarctica and northern continents.
