Mr. gordon's science students are studying models of the sun-earth-moon system. mr. gordon is using this model to show his students how the three bodies are arranged during a solar eclipse. one of his students commented that as a scale model, this model is not accurate. is the student correct?

Its very likely

Explanation:

It is impossible to answer this question without the figure. Nevertheless It is highly unlikely that any model used in a classroom is a properly scaled model because the earth fits 30 times inside the moon's orbit and 12000 times in earth's orbit around the sun. So if the earth is represented as a 1 centimeter circle the entire model would have to be 240 meters wide (More that 2 football fields)

The Sun is too small.

Explanation:

The Sun is too small. The Sun is 109 times bigger in diameter than Earth. If the Earth in the model has a 6" in diameter, then the Sun must be 6" X 109 in diameter.

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion
