identify and describe the environmental impact of development on the amazon basin.​

Answers

The Amazon Basin is located in brazil. For centuries, this has protected the area, people, and the animals residing in it. Forest recession has occurred in the past 30 years due to increased industry and population growth through road projects, settlement initiatives, and industrial development.

The Amazon Basin includes a diversity of traditional inhabitants as well as biodiversity in both flora and fauna. These peoples have lived in the rain forest for thousands of years, and their lifestyles and cultures are well-adapted to this environment. Contrary to popular belief, their subsistence living methods do not significantly harm the environment. In the past few decades, the real threat to the Amazon Basin has been deforestation, poaching, and cattle ranching by transnational corporations.

Oil and gas development often also takes a heavy toll on the environment and local people; especially in rainforest areas where it can cause displacement of local people, air and water pollution, and construction of roads that open previously inaccessible areas to deforestation.

That said, even a new NASA study shows that over the last 20 years, the atmosphere above the Amazon Basin has been drying out, increasing the demand for water and leaving ecosystems vulnerable to fires and drought. It also shows that this increase in dryness is primarily the result of human activities.

Summary: all impacts caused by human development in the Amazon Basin is causing the atmosphere to go bad, the crops and indigenous plants to die at alarming rates, the water to be polluted, and the animals and humans who are indigenous of the area suffer the consequences.

1. How do the waters of the earth's oceans help distribute heat from one place to another?
Currents influence winds through the Coriolis effect.
Currents carry warm water from the Equator to the poles.
Warm water stays far below the ocean's surface.
Cold water stays just below the ocean's surface.

Answers

Answer:

Explanation:

How does wind affect ocean currents?

Major surface ocean currents in the open ocean, however, are set in motion by the wind, which drags on the surface of the water as it blows. ... The winds pull surface water with them, creating currents. As these currents flow westward, the Coriolis effect—a force that results from the rotation of the Earth—deflects them.

Which statement is not correct about the use of the forests to regulate water and filtration?
Tree planting can invariably bring down temperatures in urban areas, especially in summers.
Forests regulate the natural supply of clean water as the canopy triggers the release of water vapor that in turn maintains precipitation.
The same strong roots filter sediments and chemicals, making for a higher-quality supply of water.

Answers

Answer:

Tree planting can invariably bring down temperatures in urban areas, especially in summers.

Explanation:

This is kind of a trick question, because all of these answers can be correct. The answer above isn't necessarily wrong, it's just the wrong answer for this question. Trees can reduce temperatures naturally, particularly through shade and evapotranspiration, which is the evaporation and transpiration of water through soil and plants.

Trees however, are part of the water cycle and do evaporate water and perform transpiration, as well as filtering sediment from erosion through their roots, providing a cleaner runoff into water sources. They can also filter chemicals, heavy metals, and even some oils from roads.
