Explain what water pollution is and state the human activities that causes water pollution.​

Answers

The presence of harmful chemicals and biological agents in groundwater that go above and beyond what is normally present in the water and may be hazardous to the environment and/or human health is referred to as water pollution. Additionally, substances that have been added to water bodies as a result of numerous human activities might constitute water contamination. Regardless of the risk they may represent to the environment and human health, any quantity of harmful substances pollutes the water. Water pollution is a hideous problem all around the world that is caused entirely by human behavior. So, what would it take to stop or in the very least reduce the rate of significant water pollution? The answer includes creating and imposing laws on how waste is disposed on a large scale, such as factories and farms, as well as educating the overall public on what each person can do to contribute to the solution instead of the problem. The major causes of water pollution in today’s society are from household sewage, industrial manufacturing, and agricultural runoff. Laws such as Clean Water Act of 1972 have been helpful but now, half a century later it is in need of an overhaul to address the polluting sources not included in the original version. Examples of which include indirect source polluting from farm and residential runoffs that carry with them pesticides, household chemicals, and even pharmaceuticals right to the steams and oceans infesting marine life and drinking waters. The ultimate solution is to come at the problem from both ends, cleanup the waste that is already in the water systems throughout the globe, but more importantly stopping or at the very least significantly cutting down on the careless polluting practices currently in place. That is why it is vital to publicize this problem, educate on the causes and effects of society’s activities, and fight for creation and enforcement of stricter laws for waste disposals.

Which volcanic hazard is most likely to cause destruction in towns located 30-60 kilometers away from a Cascade Range (very explosive) volcano

Answers

Lahars volcanic hazard is most likely to cause destruction in towns located 30-60 kilometers away from a Cascade Range volcano.

Lahar comes from Indonesian word which describe a mudflow or debris flow that originates on the slopes of a volcano. Small debris flows known to be very common within the Cascades, where they form in the times of heavy rainfall, rapid snow melt, and by shallow land sliding. These relatively small debris flows infrequently give way some miles down valleys. Inside the Cascades, the word lahar is normally reserved for larger events that occur in addition with volcanic eruptions, and travel many miles down valleys and affects the local communities. Lahars may occur by rapid melting of snow and ice during eruptions, by liquefaction of giant landslides (also called debris avalanches), by breakout floods from crater lakes, and by erosion from fresh volcanic ash deposits during heavy rains. Amid and immediately following volcanic eruptions, lahars can demeanor the foremost severe hazard to more populated valleys downstream from Cascades volcanoes.

So, the lahars volcanic hazard can cause destruction in towns located 30-60 kilometers away from a Cascade Range volcano.

What is the primary reason why mountains substantially taller than Mt. Everest are unlikely to arise on Earth

Answers

One of the main reasons for the fact that is very unlikely for mountains to rise taller than the Mount Everest on Earth is because, mountains give way under their own weight because of the high geothermal gradient in the crust.

The geothermal gradient, which is unchanged from the paleo-geothermal gradient, is the rate of increase in temperature per unit depth in the Earth's interior caused by the core heat flow.In much of the world, it is approximately 25 °C every mile of depth (1 °F per 70 feet of depth) outside of tectonic plate borders.At oceanic spreading centers (mid-ocean ridges) or island arcs where magma is near to the surface, the largest gradients—40–80 K km1—are measured. The subduction zones, where cold lithosphere sinks into the mantle, have the lowest gradients. Old stable continental crust has a gradient of 20–30 K km1.

From the above, it is clear why mountains taller than the Mount Everest, are unlikely to arise on Earth.

What is differential heating? evaluate the requirement that differential heating must take place before wind will blow. do any winds exist without differential heating?

Answers

The difference in warming refers to the change in the pattern of solar radiation received on the surface of the earth. We know that tropical latitudes receive more solar radiation than higher latitudes and poles. Therefore, this fluctuating solar radiation leads to different warming of the Earth's surface in different places.

Because the surface heating method is different, the air heating method is also different upwards. The higher the temperature, the lower the pressure, and the lower the temperature, the higher the pressure, resulting in a difference in air pressure. Therefore, the wind flows from high pressure to low pressure. Basically, it is the warming of different surfaces that causes the wind.

If there is no difference in surface heating such as water, land, low latitude, or high latitude, there is no pressure difference. Therefore, the wind has no gradient or flow. Therefore, without differential heating, there can be no wind.

A glacier that had not changed its size or shape for a long time is now getting shorter. What does this tell you

Answers

Answer:

A glacier that had not changed its size or shape for a long time is now getting shorter. What does this tell you? Snowfall has decreased, or melting has increased, or both. it might be helpful

Glacier changing its size tells us that either melting has increased due to rise in temperature, or snowfall has reduced, or both.

Why glaciers are melting?

Many glaciers have been melting at an increasing rate since the early 1900s throughout the world. This phenomenon is primarily the result of human activity. Near particular, since the industrial revolution, emissions of greenhouse gases such as carbon dioxide have increased temperatures, even more in the poles, and as a result, glaciers are rapidly melting, calving off into the sea, and retreating on land.

Why snowfall is reducing?

More water evaporates from the land and oceans as a result of warmer temperatures, which increases precipitation, storm size, and precipitation variability in some regions. Generally speaking, a warmer temperatures results in more of this precipitation falling as rain rather than snow.

When comparing the catastrophic eruption in Sumatra 71,000 years ago and the 1991 eruption of Mt. Pinatubo, we find that "both eruptions caused a drop in the average temperatures across the Earth".

What is catastrophic eruption in Sumatra and in Mt. Pinatubo?

The most recent Toba eruption was a supervolcano eruption that took place at the location of the present-day Lake Toba in Sumatra, Indonesia, some 71,000 years ago.

Reason for Toba eruption is-

The greatest known volcanic explosion on Earth in the last two million years, the Toba volcano eruption, produced a steep-walled crater that eventually became the source of the ancient lake. Supervolcanic eruptions are exceedingly unusual and massive eruptions like this one.

On June 15, 1991, Mount Pinatubo in the Philippines saw the second-biggest volcanic explosion of this century and by far the largest eruption to affect a highly populated area. The eruption caused massive mudflows, high-speed avalanches of hot ash and gas, and a hundreds-mile-wide cloud of volcanic ash.

Reason for Mount Pinatubo eruption is-

More than 32 km (20 mi) of magma beneath Mount Pinatubo was surging toward the surface, causing tiny volcano tectonic earthquakes and massive steam explosions that blew three holes in the volcano's north slope.
