Earth's Spheres Quiz

Nitrogen is the most abundant gas in Earth's atmosphere, making up about 78% of it. It exists as a diatomic molecule, meaning two nitrogen atoms are bonded together. This nitrogen gas is essential for many biological processes and is a vital component for the growth of plants. Therefore, it is correct to say that the nitrogen in the air is indeed part of the atmosphere.

When it is stated that a change to one system will affect "All other spheres," it means that any modification or alteration made to the given system will have an impact on all the other interconnected systems or spheres. This suggests that there is a high level of interdependence and interconnectedness among these spheres, and any change in one will inevitably have consequences for the others. Therefore, this answer implies that there is a strong relationship and influence between the various systems, and they are not isolated or independent from each other.

Large mines can have significant impacts on the environment, affecting the atmosphere, biosphere, and hydrosphere. Pollution is a common consequence of mining activities, as it can release harmful substances into the air, water, and soil. Vegetation removal is another consequence, as mining often requires clearing large areas of land, leading to habitat destruction and loss of biodiversity. Additionally, mining can alter water flow patterns, disrupting natural drainage systems and affecting aquatic ecosystems. Therefore, all of the above options are valid changes that can occur when large mines are dug in the ground.

When a volcanic eruption occurs, it releases gases and ash into the air. The geosphere refers to the solid part of the Earth, including the land and rocks, while the atmosphere refers to the layer of gases surrounding the Earth. In this scenario, the interaction is between the geosphere, which releases the gases and ash during the eruption, and the atmosphere, which receives and disperses them. Therefore, the correct answer is geosphere and atmosphere.
