Phil observes that when he turns on a flashlight, chemical energy from the batteries is transformed into light energy. Phil trie
grin007 [14]

Answer:

A. a lamp being turned on

B. a toaster being used to toast bread

D. a car horn honking

Explanation:

Energy transformation is the conversion of one form of energy to another form in accordance with the law of conservation of energy. According to this question, Phil is observing a flashlight, which turns chemical energy (batteries) into light energy.

From the examples given in this question, the following are examples of scenarios that involve energy transformation:

- A lamp being turned on: This converts chemical energy to light energy.

- A toaster being used to toast bread: This converts electrical energy to heat energy.

- A car horn honking: This converts electrical energy to sound energy.

Note that, melting of a chocolate does not transform any form of energy.

Describe the effects of the increase in temperature over the past 100 years.
Bezzdna [24]

Global surface temperature has been measured since 1880 at a network of ground-based and ocean-based sites. Over the last century, the average surface temperature of the Earth has increased by about 1.0o F. The eleven warmest years this century have all occurred since 1980, with 1995 the warmest on record. The higher latitudes have warmed more than the equatorial regions.

Beginning in 1979, satellites have been used to measure the temperature of the atmosphere up to a height of 30,000 feet. The long-term surface record and the recent satellite observations differ, but that fact is not surprising: the two techniques measure the temperature of different parts of the Earth system (the surface, and various layers of the atmosphere). In addition to this, a variety of factors, such as the presence of airborne materials from the 1991 eruption of the volcano Mt. Pinatubo, affect each record in a different way. Satellite observations were initially interpreted as showing a slight cooling, but more recent analyses accounting for natural, short-term fluctuations imply warming, just as the ground-based measurements have indicated over a longer time period. As more data from the satellite record become available, and as the quality of measurements is improved, comparison of these two records should yield additional insights.

A warmer Earth speeds up the global water cycle: the exchange of water among the oceans, atmosphere, and land. Higher temperatures cause more evaporation, and soils will tend to dry out faster. Increased amounts of water in the atmosphere will mean more rain or snow overall. We may be seeing the first signs of changes in the water cycle. Since the beginning of the century, precipitation in the United States has increased by about 6 percent, while the frequency of intense precipitation events (heavy downpours of more than two inches per day) has increased by 20 percent. Such events can cause flooding, soil erosion, and even loss of life. In some midcontinent areas, increased evaporation has led to drought because the heavy rains fell elsewhere.

There is also evidence that ecosystems are reacting to warming. Between 1981 and 1991, the length of the growing season in the northern high latitudes (between 45oand 70o N) increased by a total of up to twelve days, as documented by satellite imagery. Greening in spring and summer occurred up to eight days earlier, and vegetation continued to photosynthesize an estimated four days longer.

Global mean sea level has risen 4 to 10 inches over the last 100 years, mainly because water expands when heated. The melting of glaciers, which has occurred worldwide over the last century, also contributes to the rise. Formerly frozen soils (permafrost) in the Alaskan and Siberian arctic have also begun to melt, damaging both ecosystems and infrastructure. Melting and tundra warming will also lead to decay of organic matter and the release of trapped carbon and methane, creating an additional source of greenhouse gases.

What waste product does aerobic organisms release into the environment that plants use during photosynthesis
Arte-miy333 [17]
Answer: Carbon Dioxide (CO2)

Aerobic organisms (like us!) are organisms that need oxygen. That means they consume oxygen (O_{2})and release carbon dioxide (CO_{2}).

That carbon dioxide is the waste product that is taken up by plants during photosynthesis to create more oxygen and sugars (as "food" for the plants). This is seen in the equation for photosynthesis, where the things that are consumed by plants are on the left of the arrow, and the things produced are on the right:
<span>6CO2 + 6H2O + light energy ==> C6H12O6 + 6O2</span>

Prairie soils (mollisols) are _______.
natka813 [3]

Correct answer: B). Easy to cultivate and fertile

The prairie is grassland soils that possess a dark colored surface and these soil are highly fertile in nature. These soils are rich in minerals like calcium and magnesium.

The dark color of soil comes from the added organic matter to the soil that comes from the roots of prairie plants. They are formed in the areas that are too dry to be forested, but too wet to be desert.

Hence, the correct answer would be option B.
