The major causes of the greenhouse effect is excessive carbon dioxide gas in the atmosphere. The greenhouse effect is a process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by green house gases, such as carbon dioxide, water vapor, metahne, nitrous oxide, and ozone. The absorbed energy warms the atmosphere and the surface of the Earth.

Answer:
A symbol that indicates the sedimentary rocks (for example, salt rocks).
Explanation:
The sedimentary rocks are formed through time by cycles of evaporation and the consequent deposition of minerals. In the case of salt rocks, for example, they are generated by the accumulation of layers of salt in the seashore through the movement of the sea waves, i.e., by the evaporation of seawater and subsequent accumulation of salt.
<span>The correct answer is d. increase the rate of breathing.</span>
<span>
Peripheral chemoreceptors (the carotid and aortic bodies) can sense hypercapnia (high CO2) and then they send a signal to the breathing centre. Breathing centre is in medulla oblongata which regulates breathing movements. When CO2 reaches a certain level, a signal is sent to trigger an inhalation and the rate of breathing is increased.</span>
