The main reason why the tectonic plates move is the conversational currents. There is magma between the upper mantle and the asthenosphere that heats up at the upper mantle. The weight is so small that the magma rises with the help of these conversational currents. When the magma has ascended towards the asthenosphere, it has nowhere to go so the magma lies along the asthenosphere. There the magma cools down again because the asthenosphere is colder than the upper mantle, which makes the magma heavier and goes back down to the upper mantle, where the magma heats up again and everything starts all over again and so it goes on over and over again. Scientists have concluded that the earth's gravity causes two other processes that also cause the tectonic plates to move.

Ridge push - in the spreading zones, the sides of the tiles are raised and slide to the side as in a slide.
Slab pull - when a plate is pulled down by gravity in a subduction zone like an anchor.

According to the geologic time scale, how is the most recent eon subdivided?

Olenka [21]

Answer:

The most recent eon is subdivided into three eras and eleven periods.

Explanation:

The geological time scale has been constructed so that it can help in better research and understanding of the past, as well as making it easier to distinguish the past and its characteristics at a certain time. There are larger and smaller divisions in the geologic time scale, with the eon being the largest unit, followed by era, and then period.

The most recent eon is the Paherozoic, starting from 542 million years ago and still going on. It is subdivided into three eras and eleven periods so far. The three eras are:

Paleozoic
Mesozoic
Cenozoic

The eleven periods are:

Cambrian
Ordovician

Identify and describe the environmental impact of development on the amazon basin.

Nadya [2.5K]

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.
