Answer:
Ben Bernanke, an economic
Answer:
<h2>Human activities contribute to climate change by causing changes in Earth's atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. ... Changing the atmospheric abundance or properties of these gases and particles can lead to a warming or cooling of the climate system.</h2>
Answer:
Global Climate change
Climate is the general weather conditions of a place over many years. Climate change is a significant variation of average weather conditions. i.e., conditions becoming warmer, wetter, or drier over several decades or more. It’s that longer-term trend that differentiates climate change from natural weather variability. Although climate change and global warming are often used interchangeably, global warming is the recent rise in the global average temperature near the earth’s surface is just one aspect of climate change.
The effects of global climate change on earth's climate are as follows:
1. Extreme weather condition
2. Air Pollution
3. Health risks
4. Rising seas
5. More acidic, warmer oceans
6. Imperiled global ecosystem
Explanation:
The effects of global climate change
World Economic Forum’s 2016 Global Risks Report, reported that the failure to mitigate and adapt to climate change will be “the most impactful risk” facing communities worldwide in the coming decade ahead even of weapons of mass destruction and water crises. Blame its cascading effects: As climate change transforms global ecosystems, it affects everything from the places we live to the water we drink to the air we breathe.
Answer:
5. pycnocline.
Explanation:
Pycnocline is the rapid change in density of ocean water with depth. With increase in depth, ocean water tends to be denser. The two major factors that determine density in ocean water are temperature and salinity(salt contents). The denser water become in the ocean the more likely it sinks easily . This is one major factor that drive Ocean currents, the process is called thermohaline circulation.
The increase in salinity of ocean water causes an increase in density . This is because the salt become tightly pack and filled the water to make it denser . This simply means an increase in saline content of ocean water causes an increase in the density.
Another factor that affects density is temperature. Water at the surface possesses higher temperature due to direct contact with the sun. Usually, the higher the temperature the less dense ocean water becomes . This is why surface water is less dense. As water becomes warm the molecule disperse, this account for it lower density . Colder water are usually higher in density .
Generally, an increase in ocean depth causes considerable increase in density because of it colder temperature and increased salinity contents.
