Answer:
The correct option is: CO₂
Explanation:
Greenhouse effect refers to the natural phenomenon by which the Sun's radiation increases the temperature of the Earth's surface.
The incoming Sun's radiation is radiated by the greenhouse gases present in the Earth's atmosphere. A fraction of the radiated energy is then absorbed by the Earth's surface, thus resulting in increase in the temperature.
<u>Thus the green house effect depends upon the amount of green house gases present in the atmosphere.</u>
The green house gases are the r<u>adiatively active gases.</u> The main four green house gases are: water vapor (H₂O(g)), carbon dioxide (CO₂), methane (CH₄) and ozone (O₃).
<u>Human activities such as burning of fossil gases and deforestation increases the concentration of </u><u>CO₂ </u><u>significantly.</u><u> Thereby contributing to the greenhouse effect.</u>
Answer:
Accelerated erosion or change in cover tend to persist and grow over time because the continuous erosion of the channel further escalate the rate of erosion by further widening of the channel unless there is a human intervention to stop this. Once the vegetative cover of a soil is altered, it leaves room for erosion (the degree of the erosion depends on the degree of loss or gain of vegetative cover). In a bad case where there is a loss of vegetative covering of the soil, erosion sets in, washing away the top soil and reducing the cover vegetation even more. These two activities are those type of activities that grows over time once they are activated.
