Why do convergent boundaries cause the formation of volcanoes? (1 point)
Responses

When two plates move away from each other, they create a crack in the crust, or a fault. This fault can go all the way to the mantle, causing magma to shoot out onto the crust.

When two plates collide, part of one plate is broken. This creates an area where the mantle is exposed to the air and magma shoots out onto the crust.

When two plates collide, one goes under the other. This creates an area of high pressure, which causes mantle rock to melt into magma and shoot out onto the crust.

Monoculture, in which farmers raise a single crop in a field every year, can damage the soil. How much of a concern is this? (1 point)
Responses

Not a serious problem anymore, because soil damage can be fixed with recent technologies.

Photosynthetic organisms, such as cyanobacteria, were some of the earliest forms of life on Earth and evolved the ability to produce oxygen as a byproduct of photosynthesis. This process resulted in a dramatic increase of oxygen on Earth, creating the current atmospheric composition that we know today. The evolution of oxygen-producing photosynthesis by cyanobacteria and other organisms led to the Great Oxygenation Event (GOE) approximately 2.4 billion years ago, marking a major transition in Earth's biosphere.

The chemical composition of Earth's oldest rocks (Archean rocks) provide evidence for this event, as some contain banded iron formations that could only have formed in the presence of oxygen. Fossil records of cyanobacteria also provide evidence of this critical transition.

The evolution of photosynthetic organisms and the subsequent increase of oxygen in the atmosphere and the oceans greatly impacted the biosphere. The GOE paved the way for the evolution of more complex, aerobic organisms that rely on oxygen for respiration. It also allowed for the development of the ozone layer, which protects the Earth's organisms from harmful levels of UV radiation. This event is considered one of the most important in the history of life on Earth and has shaped the subsequent history of the Earth's biosphere.
