Which of the following best explains the effect of climate change on polar regions?
Which of the following best explains the impact of climate change on polar regions? … Polar regions are warming more quickly than other regions because warming decreases the coverage of high-albedo ground cover like ice and snow.
How has global climate change affect polar ice in the Arctic the Antarctic apes?
How has global climate change affected polar ice in the Arctic? The Antarctic? Antartica has experienced melting and has lost 1,300 gigatons of ice. … GLobal ocean currents may shift as a result of more fresh water being released from melting ice.
What are the main drivers of climate change?
The main driver of climate change is the greenhouse effect. Some gases in the Earth’s atmosphere act a bit like the glass in a greenhouse, trapping the sun’s heat and stopping it from leaking back into space and causing global warming.
What two forms of energy does the sun primarily radiate or emit quizlet?
Gamma rays and X-rays are two forms of longwave radiation emitted by the earth. Hotter objects radiate energy at shorter wavelengths. The energy radiated by the sun is referred to as longwave radiation. Most of the energy radiated by the earth is in the form of thermal infrared radiation.
What is the effect of climate change on polar regions?
Climate change is already altering Arctic habitats. The region has warmed by nearly 10 degrees Fahrenheit since 1900, and continues to warm two to three times faster than the average for the rest of the world. Summer ice cover is shrinking, permafrost is melting and coastlines have been exposed to erosion.
Which of the following best describes the cause of the greenhouse effect on Earth?
The greenhouse effect is caused by the atmospheric accumulation of gases such as carbon dioxide and methane, which contain some of the heat emitted from Earth’s surface. The atmosphere allows most of the visible light from the Sun to pass through and reach Earth’s surface.
How climate change affects the Arctic?
Melting ice speeds up climate change.
Global warming is causing Arctic ice to melt – ice reflects sunlight, while water absorbs it. When the Arctic ice melts, the oceans around it absorb more sunlight and heat up, making the world warmer as a result.
How are Arctic foxes affected by climate change?
The Arctic fox faces a multitude of threats from climate change: its sea ice and tundra habitat are shrinking, its lemming prey are becoming less abundant in some areas, and it faces increased competition and displacement by the red fox which is moving northward as temperatures warm. LOSS OF SEA ICE AND TUNDRA HABITAT.
How does climate change impact the Arctic?
The average temperature of the Arctic has increased 2.3°C since the 1970s. Ice dependent species such as narwhals, polar bears, and walruses are at increasing risk with shrinking sea ice cover. … As the Arctic loses snow and ice, bare rock and water absorb more and more of the sun’s energy, making it even warmer.
What are climate change indicators and drivers?
Temperatures are rising, snow and rainfall patterns are shifting, and more extreme climate events—like heavy rainstorms and record-high temperatures, are already taking place.
Can climate change be mitigated?
Mitigation – reducing climate change – involves reducing the flow of heat-trapping greenhouse gases into the atmosphere, either by reducing sources of these gases (for example, the burning of fossil fuels for electricity, heat or transport) or enhancing the “sinks” that accumulate and store these gases (such as the …
How do changes in the atmosphere drive climate change and other changes in global systems?
How do changes in the atmosphere drive climate change and other changes in global systems? Human activities that affect global systems are changing Earth’s atmosphere faster than it has changed historically. … When a 5300-year-old ancient human emerged from melting glacier ice, it was noted that Earth is getting warmer.
What 2 forms of energy does the sun primarily radiate or emit?
All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat.
What type of radiation does the sun primarily emit?
Though the sun emits all of the different kinds of electromagnetic radiation, 99% of its rays are in the form of visible light, ultraviolet rays, and infrared rays (also known as heat). Man-made lamps can also emit UV radiation, and are often used for experimental purposes.
What type of radiation does the sun emit quizlet?
a kind of radiation including visible light, radio waves, gamma rays, and X-rays, in which electric and magnetic fields vary simultaneously. is an electromagnetic radiation with a wavelength from 10 nm (30 PHz) to 400 nm (750 THz), shorter than that of visible light but longer than X-rays.
