Mention and explain five causes of climate change ​
mixer [17]

Answer:

Cause #1: Variations in the Sun's Intensity

The Earth receives its warmth from the sun, so it's reasonable to suspect that our home star may be one of the reasons for global warming. Although the amount of energy coming from the sun does vary and may have been responsible for warming in the past, however, NASA and the Intergovernmental Panel on Climate Change (IPCC) have ruled this out as a cause of the current warming trend. The average energy coming from the sun generally has remained constant since 1750, and the warming does not occur uniformly throughout the atmosphere. The upper layer is actually cooling as the bottom layer becomes warmer.

Cause #2: Industrial Activity

Since the Industrial Revolution, humans have been burning fossil fuels such as coal and petroleum for energy, which releases carbon dioxide into the atmosphere. A quarter of this is for heat and electricity, while another quarter is for other industrial processes and transportation, which includes gasoline- or diesel-powered cars, trucks, trains and airplanes. The other half of the energy is used for various other purposes, including agriculture, cement production and oil and gas production. These processes also release other greenhouse gases, such as methane and CFCs, although the concentration of CFCs has declined since their use was banned in 1988.

Cause #3: Agricultural Activity

The agricultural practices that produce food for the people on earth is another of the human causes of climate change. The use of both commercial and organic fertilizers releases nitrous oxide, a powerful greenhouse gas. Methane, another important greenhouse gas, comes from many natural sources, but also from the digestive systems of livestock raised for meat production as well as the decomposition of waste in landfills and the burning of biomass.

Cause #4: Deforestation

The increased demand for meat and dairy cattle has lead to the creation of feed lots in otherwise forested areas. Logging for wood and paper and clearing for crop production also requires trees to be cut, sometimes illegally. One mature tree absorbs as much as 48 pounds of carbon dioxide each year, and by one estimate, 3.5 to 7 billion are cut every year. According to Scientific American, deforestation is responsible for 15 percent of the greenhouse gases in the atmosphere.

Cause #5: Earth's Own Feedback Loop

As the atmosphere warms, it is able to hold more water, which is already the most abundant greenhouse gas. This creates a feedback loop that accelerates global warming. It also creates more clouds, rainstorms and other symptoms of climate change. At the poles, the warming of the atmosphere melts the ice cover, exposing water, which is less reflective than ice. The water absorbs the sun's heat, and the oceans also become warmer as a result.

which of the following is the unit of measurement used to describe the severity of an earth quake? Velocity, magnitude, volume,
Rina8888 [55]

Answer:

Magnitude

Explanation:

Earthquakes are typically measured in units of magnitude. The news usually use the most popular measurement scale called the Richter Scale which rates an earthquake by the size of its seismic waves on a scale from 1 to 10.

Ex. Mexico had a 7.1 magnitude earthquake

Hope this helps :)

if it did please mark brainliest :D
