Answer:

Two possible reasons for the massive extinction at the end of the Paleozoic Era are an asteroid collision and massive volcanic eruptions.

Explanation:

The massive extinction that occurred at the end of the Paleozoic Era is the biggest extinction from what is known so far. The majority of the species died out, and whole families of animals and plants were wiped out of the face of the Earth. It was only small and highly adaptable organisms that managed to survive and give rise to the later life-forms.

The two possible reasons for this massive extinction are an asteroid impact and massive volcanic eruptions. An asteroid collision would have created drastic changes in a matter of minutes and hours, with effects lasting for a long period of time, thus eliminating the majority of the life. Massive volcanic eruptions, with the Siberian super-volcano being the prime candidate, may have caused enormous amounts of carbon dioxide and sulfur dioxide to end up in the atmosphere, thus rapidly changing the living conditions on the planet.

Which two ancient civilizations practiced human sacrifice
Alex777 [14]
Maya and Inca but Aztec could be in there too

Explanation:

The Incas performed child sacrifices during or after important events, such as the death of the Sapa Inca (emperor) or during a famine

Generally only high status prisoners of war were sacrificed, with lower status captives being used for labour. Human sacrifice among the Maya is evident from at least the Classic period (c. AD 250–900) right through to the final stages of the Spanish conquest in the 17th century.

In addition to slicing out the hearts of victims and spilling their blood on temple altars, the Aztecs likely also practiced a form of ritual cannibalism. An Atztec human sacrifice atop the Mesoamerican temple pyramid.

Natali5045456 [20]

Answer:

Explanation: Dear Sirs:

    I am writing today to urge you as strongly as possible to stop your deforestation program in the rain forest there in South America. Although for you the objective is financial gain, for the rest of us it is the destruction of land, habitats, people and eventually, the Earth.

   Deforestation is a process where large areas of forests are cut down to be used for farming, grazing land for cattle, and housing. This is especially true inn the South American rain forest where you are working. These are not necessarily bad things, but the effects of deforestation are devastating. Deforestation is achieved by cutting or burning of trees from a widespread area. Why does this matter?

    When deforestation occurs in an area, animals and plants are forced to move from their natural habitat. For many of these species they are unable to survive in new forced into areas. When the trees are cut down, the stumps are then burned to release nutrients into the soil to enrich it for farming. This is called, "slash and burn." However because of the heavy rains,and no tree roots to hold the soil, the nutrients are washed away and soon the farmers must move to a new area, and start the process all over.

      Further, deforestation can cause climate change. Obviously without the trees available to capture the Greenhouse gases, like carbon dioxide, stopping the gases from accumulating in the atmosphere and warming our planet. Climate change is a real issue that must be addressed if our planet is to survive.

       With all of these problems, what are the benefits? Who wins? Who loses? The benefits are to your company who now have a large tract of freshly cleared land that can be used for farming, cattle grazing, logging or housing. As always the almighty dollar comes to the forefront. The losers are the plants, animals and indigenous people who live in that area. Forced to relocate, many of all the groups will not survive. With the increased use of deforestation, the benefits are far outweighed by the cost- our planet Earth.

        What are the alternatives to land desertification?  There are better and more innovative ways to grow food and clear land, one of which is sustainable land management. It is a process to prevent, minimize, or reverse land degradation. There are organizations worldwide that will help you to find better solutions than deforestation to reduce carbon pollution, to safeguard arable land, repair degradable land and to manage water supplies more effectively.

          In closing, I strongly urge you to reconsider what you are doing in an area that can ill afford any more destruction. Why does it matter? Perhaps it doesn't to us in 2020, but to our children's children it will matter greatly if climate change destroys the Earth.

Reason for the colonization of India
Vlad [161]
In addition to a desire for economic profit, nationalism also served as a reason for colonization. After the French Revolution, European nations had a strong sense of national pride, and felt that in order to prove themselves as a strong world power, they would need to gain control of other countries.
