Tectonic activity has played a significant role in shaping the landscape of North Africa.
The continent of Africa sits on the African Plate, which is slowly moving northwards and colliding with the Eurasian Plate. This collision has resulted in the formation of the Atlas Mountains, which run through Morocco, Algeria, and Tunisia.
The collision also caused the formation of the Mediterranean Sea, as the African Plate has been pushing upward and forming mountain ranges.
An example of a land formation that illustrates the effect of tectonic activity in North Africa is the Great Rift Valley.
This valley, which runs through several countries in East Africa, including Ethiopia and Kenya, was formed as a result of the separation of the African Plate into multiple plates, resulting in the formation of a rift valley.

What effect does the exhaust (emissions) from mining equipment used in the Canadian Shield have on the environment?
answer choices
It contaminates soil.
It reduces air quality.
It pollutes groundwater.
It heats the atmosphere.
The exhaust (emissions) from mining equipment used in the Canadian Shield reduces air quality.
The Canadian Shield, which is notable for mining minerals like diamond, gold, copper, and many more, surrounds the Hudson Bay. The area of land containing these minerals has been extensively dug up and mined by miners who have taken advantage of the area's rich mineral soil by doing so. As a result, the area of land with all these minerals is now destroyed.
Since many people in the Canadian Shield region depend on mining for their livelihood, a sizable amount of the Canadian Shield has been exploited, releasing dust and toxins into the sky. This merely leads to a worsening of the living conditions for individuals because of the lowered air quality brought on by these substances.

3. Louisiana black bears live on territories at a rate up to 1. 7 bears per square mile. What would
happen if their density increased?
Answer: If the Louisiana black bear population density increased, the bears would begin to compete for resources such as food, water, and shelter. This could cause an increase in aggressive interactions between bears, increased mortality rates, and decreased reproduction rates. Additionally, increased bear densities could also lead to more frequent and serious human-bear conflicts.
Explanation:
Bear populations in the state are believed to be between 750 and 1000, although they are increasing as more natural habitat is being restored. For such populations, "we are witnessing range extension," claimed Davidson.
Black bears in Louisiana would start to compete with one another for resources like food, water, and shelter if their population density rose. This could result in more aggressive bear encounters, higher fatality rates, and lower reproduction rates. Increased bear populations may potentially result in more frequent and dangerous human-bear interactions.
According to earlier research, bear population densities typically vary between 0.5 and 1.0 bears per square mile (CDFW 1993). The Central Coast, the Transverse Mountain Range, the San Gabriel and San Bernardine Mountains are all included in the Western/Southern sub population.

3.3. about how long after shaking begins during the tangshan earthquake does it take the last building collapses?
Answer:
not that long, because "in minutes, 85 percent of the buildings in Tangshan collapsed or were rendered unusable, all services failed, and most of the highway and railway bridges collapsed or were seriously damaged."
Explanation:
In 14 to 16 seconds after shaking begins during the tangshan earthquake does it take the last building collapses.
The Tangshan earthquake of 1976. The surrounding area had earthquake intensities of VIII (severe) or above on the modified Mercalli scale, covering an area of around 3,650 square miles (9,500 square kilometers). The intensity at Tangshan, China, reached X. (extreme). The region's unusually deep sand soil was shaken for 14 to 16 seconds, turning much of it into a fluid-like mass (liquefaction).
ew buildings in the impacted area were attached to bedrock, therefore the earthquake and subsequent liquefaction of the soil destabilized and brought down the majority of the structures. More than 85% of Tangshan's unreinforced homes, multistory buildings, and other structures were badly damaged or destroyed by the earthquake.

what are some ways water moves on earth’s surface?
Answer: it flows across land, into the ground, and then moves through the ground. This is known as runoff - infiltration and percolation - ground water, where it then becomes the use for plants, etc.
Explanation:
Runoff, infiltration, and percolation are some ways that liquid water moves across Earth's surface (groundwater).
Plants absorb groundwater, which then evaporates from the plants and enters the atmosphere (transpiration). Ice and snow that is solid can instantly turn gaseous (sublimation). Water vapor can also solidify in the opposite situation (deposition). Life on Earth depends on water. Water, which exists in three states (solid, liquid, and gas), connects the main components of the Earth's climate system.
The water cycle demonstrates how water is constantly moving both inside the Earth and in the atmosphere. It is a complicated system with a wide range of processes. Water vapor is created when liquid water evaporates, and this water vapor then condenses to form clouds and falls back to earth as rain and snow.

Why does Vancouver have higher temperatures than Guelph even though itis
further north?
Vancouver has higher temperatures than Guelph because it is located on the coast, which allows for the moderation of temperatures by the nearby Pacific Ocean.
Guelph, on the other hand, is located further inland and does not have the same temperature-moderating influence. Additionally, Vancouver has a milder climate due to its location in the lee of the coastal mountains which blocks cold Arctic air masses.
What contributes to higher temperatures of a region?The increase in greenhouse gases caused by the combustion of fossil fuels, agricultural activities, and deforestation, which has resulted in an increase in global average air temperatures. The ocean absorbs approximately 90% of the excess atmospheric heat, raising average ocean temperatures.
In urban areas, the use of asphalt and other dark-colored materials can significantly increase the amount of sunlight absorbed. This results in urban heat islands, where cities have higher temperatures than surrounding areas.
