What contributed to the Mass Extinction in the Permian Period?
A. The Continents drifted into each other creating massive earth quakes that shattered the continents into small islands.
B. The elimination of oxygen
C. Volcanic Eruptions

Answers

Answer 1

Answer:

The Mass Extinction at the end of the Permian Period was the result of volcanic eruptions.

Explanation:

The Permian was a period when there was lush vegetation around the globe, high diversification among the animals, and many lineages that later gave rise to more familiar animal and plant groups that occurred during this time. This picture of the world suddenly ended though, and it did with the biggest mass extinction that we know off. The reason is still not 100% confirmed, but it is most commonly accepted that it was masive volcanic eruptions that caused this.

In what is now Siberia, there was a giant super-volcano, and this ancient volcano is seen as the primary reason for the rapid changes in the living conditions but also contributing to the activation of other volcanoes. It is believed that the amount of carbon dioxide, sulfur dioxide, ashes, and pyroclastic material released was so massive that the whole Earth was wrapped in them, blocking the sunlight, changing the climate rapidly, contributing the massive acidic rainfall, etc. The end result was near extinction of almost all life, and the survivors were just small and highly adaptable organisms that later gave rise to the organisms of the Mesozoic and Cenozoic.

describe the relationship between population growth, consumption, and the environment.

Answers

The relationship between population growth, resource consumption, and environmental degradation is complex. ... Consumption patterns have the most effect on ozone depletion, while population growth threatens biodiversity of and within species through the destruction of ecosystems.

Answer:

Populations growth, Consumption, and the Environment are honestly like a love triangle. The population is affecting the consumption rates in the world because the more people the more things needed for people to consume and the more things that need to be made for consumption the more people mass produce things like crops that use pesticides so they can make more and larger products the use of chemicals in pesticides harm the environment. From there it gets into a lot more confusing explanations but the gist of things is (bad environment = bad consumption and bad consumption = lower population).

What do CAM plants do to help reduce the loss of water and still capture carbon dioxide? B. They bring in water and CO2 through their roots and stems. C. CAM plants close the stomata during the day and open them at night. A. CAM plants open their stomata during the day and close them at night.

Answers

Answer:

C. CAM plants close the stomata during the day and open them at night.

The correct option is A. CAM plants to help reduce the loss of water and still capture carbon dioxide by CAM plants opening their stomata during the day and closing them at night.

What is the advantage of CAM plants?

Increased water use efficiency (WUE) is thought to be the main advantage of CAM for terrestrial plants since stomatal opening in the dark period results in significantly less water loss through transpiration than opening in the light period.

CAM plants, in contrast to those that grow in more humid settings, take in and store carbon dioxide at night when water is less likely to drain through open pores in their leaves. When the plant is using sunlight to turn carbon dioxide into energy throughout the day, the pores, also known as stomata, remain closed to reduce water loss.

Thus, A is the ideal selection. Because CAM plants open their stomata during the day and close them at night, they can assist reduce water loss while still capturing carbon dioxide.

Explanation:

The "lithosphere" is made up of the tectonic plates. These plates come from the crust and uppermost mantle of the Earth. It is divided into the Major Plates, Minor Plates and Microplates. The extremely high pressure below causes the rocks in the mantle to melt. These molten rocks cause convection currents resulting to the mantle moving. This then affects the tectonic plates above to move. Such movement is called "plate tectonics."

What type of climate does most of Western Europe have? What type of climate does most of Eastern Europe have?​

Answers

Answer:

Most of Western Europe has a marine west coast climate, while most of Eastern Europe has a humid continental climate.

Explanation:

Western Europe is generally a region dominated by lowlands. It is exposed to heavy influences from the ocean, with the Gulf Stream being the dominant ocean current that influences the climate. The ocean manages to make the climate in this part of Europe mild throughout the year, but also with high amounts of precipitation, thus it falls into the category of marine west coast climate.

Eastern Europe is located deeper into the continental mass, and even though it is also dominated by lowlands, it has a much more pronounced continental influence in its climate. The summer temperatures tend to get high, while the winter ones very low, but because there aren't natural barriers with Western Europe, the ocean manages to have an impact as well, bring in solid amounts of precipitation. The climate in this region is predominantly of humid continental type.

The map shows the physical and manmade elements of the Merritt Island National Wildlife Refuge including multiple picnic areas, visitor centers, roads, as well as names of islands and bodies of water. The Merritt Island National Wildlife Refuge is a series of barrier islands and bodies of water from the Atlantic Ocean to the inland coast of Florida.

Using complete sentences, identify and explain two causes of water pollution, two causes of air pollution, and the effects of both in South and Southeast Asia.

Answers

Answer: One of the major environmental concerns in South and Southeast Asia is pollution. Water pollution in the region is caused by industrial waste and untreated sewage. Industrial waste often travels downstream and affects the water supplies in cities and farms. Cities often dump sewage into rivers without treating and cleaning the water. The untreated water contains bacteria or parasites. People can become very sick when they drink the polluted water or use it to grow crops. People may end up with severe diseases or long-term health conditions. Air pollution is caused by slash-and-burn farming, fires, and airborne chemicals from vehicles and industries. The smoke and haze released into the air can travel hundreds of miles and affect entire regions. People can become ill when they breathe the air.
