''Single-family farms are making higher profits'' and ''mechanized farms require a larger labor force than traditional farms'' are the two statements that are not true about the modern day agriculture.
Single-family farms are not making higher profits, thy are in fact making much less profit, and especially in the developed countries this type of farms are systematically brought to minimum and are on the verge to stop existing.
Mechanized farms do not require larger labor force, totally opposite, they require much less labor force. The whole point of the mechanization is to lower the requirements for labor force and increase the speed and efficiency of the work, so this made it possible that much fewer people to be able to do much more work with the help of the mechanization.
Answer:
The best answer to the question: The greenhouse effect is driven by the fact that greenhouse gases are:___, would be: Good absorbers of radiation at all wavelengths.
Explanation:
Under normal circumstances, the Earth receives energy from the sun and also produces a bit of its own energy. The energy that arrives from the sun is usually known as shortwave radiation, while the energy that is both absorbed by the Earth´s atmosphere, and the energy produced by Earth itself, becomes part of what is known as the longwave radiation. Greenhouse gases, like water vapor, carbon dioxide and methane trap both longwave and shortwave radiation, which should usually be expelled to a certain extent towards space, and maintain them trapped inside the atmosphere. This bouncing effect between the shield created by the gases and the lower atmosphere, should normally be controlled by the amount of atoms of gases in the higher atmosphere. However, in the greenhouse effect, what is happening is that the amount of gases is too high, and therefore they are trapping most of the radiation, both longwave and shortwave, and keeping it in, allowing the climate to warm up.

Explanation:
It has been reported that glaciers lost more than nine trillion tons of ice which in turn led to a twenty seven (27) millimeter increase in global sea levels over the period in review. Glaciers in Alaska have been seen to be the major contributor, then followed by the melting ice fields in pentagon and Artic areas.
Answer:
he Earth zips around the Sun at about 67,000 miles per hour, making a full revolution in about 365 days – one year on Earth. Mars is a little slower, and farther from the sun, so a full circuit takes 687 Earth days – or one Mars year.
