There are multiple reasons why the fossils of the animals and plants of the more distant past are much more rare than the fossils of the animals and plants from the past few hundred million years. The earlier life organisms were much less complex, often lacking solid body structures. That means that the chances that they can be preserved are very low from the start. The fossils can not last forever, and in order for fossils to be preserved over such a long time there has to be very specials conditions in which the fossils have been preserved, and that is very rare. The movement of the tectonic plates has resulted in the disappearance of parts of some plates, or even all of them, while also creating new ones. The parts of the oldest crust have almost entirely been destroyed through subduction, thus getting below other plates and being melted in the astenosphere.

Modern agriculture is no longer an environmentally intrusive human activity - False
Approximately 20% of U.S. workers are employed on farms. - False
Explanation:
Global cultivated area on the planet is not increasing significantly, due to high efficiency modern farming practices. - This is one of the reasons, albeit not the only one.
Henry Wallace is regarded as the father of the Green Revolution. - The father of Green Revolution is Dr. MS Swaminathan. He improved the production of crops and promoted sustainability.
Modern agriculture is no longer an environmentally intrusive human activity. - Pollutants, problems with irrigation and degradation of the soil are issues in the modern agriculture.
Approximately 20% of U.S. workers are employed on farms. - According to USDA is 11%.

Answer:
rocks that are pulled apart are under tension. rocks under tension lengthen or breaks apart. tension is the major type of stress at divergent plate boundaries. when forces are parallel but moving in opposite directions, the stress is called shear.
