Answer: Carbon Dioxide
Explanation: Soil aeration is the process that provides the air to the plants and maintains the flow of oxygen and carbon dioxide gases. These are the two most vital gases for the life process of the soil to provide it to the plants and other micro organisms. It provides these gases so that there can be production in the plant through soil.
Explanation:
long term and lasting progress
Answer:
D. Fissure
Explanation:
On the image, we have a fissure. The fissure is a linear volcanic vent through which there are eruptions occurring. The fissures are connected with the volcano, but they can be tens of kilometers away from the volcano, or even more. This makes them very dangerous, as they can occur pretty much everywhere around the volcano, suddenly erupting from bellow the ground, making explosions, cracking the ground, and causing fires.
Answer:
high temperature and high pressure
Explanation:
Coal is one of the solid minerals found underground. Coal is believed to have been formed from vegetation during the carboniferous era. The decomposition of these materials under pressure in the absence of air led to the formation of coal.
In the process of carbonization, the vegetation was converted in stages to peat, lignite, bituminous coal and anthracite.
The formation of anthracite is favored by high temperature and high pressure underground.
