Mention and explain five causes of climate change ​

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.

Explain the Theory of Plate Tectonics. Write a claim below that explains how the continents moved over time and introduces 3 pie
melomori [17]

Answer:

theory dealing with the dynamics of Earth’s outer shell—the lithosphere—that revolutionized Earth sciences by providing a uniform context for understanding mountain-building processes, volcanoes, and earthquakes as well as the evolution of Earth’s surface and reconstructing its past continents and oceans.

The concept of plate tectonics was formulated in the 1960s. According to the theory, Earth has a rigid outer layer, known as the lithosphere, which is typically about 100 km (60 miles) thick and overlies a plastic (moldable, partially molten) layer called the asthenosphere. The lithosphere is broken up into seven very large continental- and ocean-sized plates, six or seven medium-sized regional plates, and several small ones. These plates move relative to each other, typically at rates of 5 to 10 cm (2 to 4 inches) per year, and interact along their boundaries, where they converge, diverge, or slip past one another. Such interactions are thought to be responsible for most of Earth’s seismic and volcanic activity, although earthquakes and volcanoes can occur in plate interiors. Plate motions cause mountains to rise where plates push together, or converge, and continents to fracture and oceans to form where plates pull apart, or diverge. The continents are embedded in the plates and drift passively with them, which over millions of years results in significant changes in Earth’s geography.

The theory of plate tectonics is based on a broad synthesis of geologic and geophysical data. It is now almost universally accepted, and its adoption represents a true scientific revolution, analogous in its consequences to quantum mechanics in physics or the discovery of the genetic code in biology. Incorporating the much older idea of continental drift, as well as the concept of seafloor spreading, the theory of plate tectonics has provided an overarching framework in which to describe the past geography of continents and oceans, the processes controlling creation and destruction of landforms, and the evolution of Earth’s crust, atmosphere, biosphere, hydrosphere, and climates. During the late 20th and early 21st centuries, it became apparent that plate-tectonic processes profoundly influence the composition of Earth’s atmosphere and oceans, serve as a prime cause of long-term climate change, and make significant contributions to the chemical and physical environment in which life evolves.

What is the most likely reason that two of the planets have rotations that are different than would be expected by the nebular h
marusya05 [52]
The most appropriate answer is "As the growing planet was clearing its path around the sun, two large planetessimals collided, tipping the growing planet". This phenomenon happened to the earth in the early stages of the development of the solar system. Scientist theorize that a planet called 'Thea' collided with the Earth. This collision resulted in the present tilt in the Earth's axis and the creation of the moon.

Lady_Fox [76]
The Northeast became a leader in commerce because of its location and early development of industrial industries. The Northeast became a manufacturing hub in the colonies and in the newly formed United States which created specialization and the growth of commerce in this region relative to the South which was more agriculturally based.

Find the value of x in the following diagram.
PIT_PIT [208]

Answer:

  x = 3.5

Explanation:

The chords are the same length, so are the same distance from center:

  3x +1 = x +8

  2x = 7 . . . . . . subtract x+1

  x = 3.5 . . . . . divide by 2
