Answer:
1- One of the most immediate and obvious effects of worldwide warming is the increase in temperatures around the world. The average worldwide temperature has increased by about 1.4 degrees Fahrenheit (0.8 degrees Celsius) over the past 100 years, according to the National Ocean-related and (related to the air outside) Management (NOAA).
The (related to the air outside) carbon dioxide concentration has risen from about 270 parts per million (ppm) before 1700 to about 355 ppm today. Climate changes, including a mean worldwide surface temperature rise of between 2.8 and 5.2°C, have been (described a possible future event) by five independent general circulation models (GCMs) for a doubling of the carbon dioxide concentration. The goals of this paper are to examine plant responses to rising carbon dioxide levels and (related to the Earth's weather) changes and to understand/explain the results of these changes on crop water use and water supplies for the United States.
2- Human activity has increased the direct warming effect of carbon dioxide in the atmosphere by 50 percent above pre-industrial levels during the past 25 years, according to NOAA's 10th Once-a-year (glass building where plants are grown) Gas Index.
I hope this helped you! Make sure you put this in your own words, and if you want me to put it in your own words for you, let me know! Also, you do not have to write all of that, just write the most important stuff! : )
Answer: e. The photic zone is where most primary production occurs.
Explanation:
The photic zone can be define as the sunlight or photosynthetic zone. It is the uppermost layer of the water body like lake, ocean, pond or others. This zone receives the maximum sunlight in the entire water body. Thus this facilitates the growth of large number of plants and other autotrophs like diatoms. This is called as the zone of primary productivity because in water the sunlight and dissolved atmospheric carbon dioxide are available for conducting the process of photosynthesis.
There are a lot of
causes in how water erodes the surface of the earth or the earth’s lithosphere.
In similar ways, stream is one example. It erodes the land surface in three

The correct answer to this is A. Devolution
Separatism is usually based on ethnicity or religion while decolonization occurs in former colonies who don't want to be colonies anymore. Supranationalism is an adjective describing something out of the domain of a single national government.
B) harsh climate and transportation distances make it difficult and costly.
