Answer:
- Earthquakes
- Tsunamis
- Volcanoes
Explanation:
An understanding of plate tectonics has saved many lives. The benefits of understanding how the Earth moves underneath our feet are enormous. Before the theory of plate tectonics, no one knew why Earthquakes occurred, why volcanoes erupted how and where they did, or why giant waves destroyed entire coastal areas or islands out of nowhere.
With the theory of plate tectonics we not only understand the orientation of the continents millions of years ago, but we also can plan cities intelligently to avoid seismically active areas. We can also predict when a tsunami will occur and gauge the potential devastation of a volcanic eruption before it happens.
Answer: Ozone is considered as chief polluting gas.
Explanation:
The ozone is a ground level pollutant. It is a colorless gas. It causes irritation in the eyes and respiratory tract. It is one of the components of smog as it causes pollution in the atmosphere. It is produced by the two primary pollutants that are nitrogen oxides and volatile organic compounds when they react with the sunlight. The ozone makes the air irrespirable. It is the main cause of throat irritation, labored breath, pain in chest and also responsible for respiratory diseases. It reduces the body's ability against infection. The ozone depleting substances like aerosol, chlorofluorocarbon are widening the ozone depleting zone as halides present in these substances react with the ozone causing depletion. This allows the entry of harmful ultraviolet radiation penetrating the atmospheric layers.
Answer:
C. undefined
Explanation:
The coordinates of the line is given as:
(4, -6) and (4, 4).
x1 = 4
y1 = -6
x2 = 4
y2 = 4
Slope =
Now insert the parameters and solve;
Slope = = undefined
The slope of the line is undefined
