The cycles within which earth's matter moves are closed systems. This means nothing is gained or lost from the system; it only changes from one form to the other. The total amount of matter on earth remains the same. Using tectonic plates as an example, divergent boundaries occur where new oceanic crust is being created. New crust is being created and simultaneously the same amount of crust is being destroyed at convergent margins.
Answer:
A
Explanation:
China produces 30 percent of the world's rice production
Answer: C. The overall temperature of the Earth will increase.
Explanation:
Let's begin by explaining that Earth has a layer, the atmosphere, that is almost transparent to solar radiation, which is composed mainly of shortwave radiation (ultraviolet (UV) and visible light). Then, this layer allows to pass most of the sunlight (visible light and a small part of the UV radiation), without being absorbed.
When this radiation reaches the Earth, it is absorbed by the water
), soil, plants, animals; well, everything that inhabits and also the buildings. Once this absorption process ends, the light turns into long wave (IR) radiation, generating heat that is then released into outer space and known as albedo.
However, due to climate change (caused by the humankind), the Earth now tends to absorb more energy than it emits to the space as IR radiation. If this process is mantained for a long term, the planet's global temperature will highly increase.
