The Earth has gone through, and continues to go through, several transformations. Select from the choices below processes or events that have impacted or impacts Earth's transformations a Volcanos, Earthquakes b parasites c erosion and weathering d Asteroids hitting the Earth

ANSWER:

A. Volcanos, earthquake

C. Erosion and Weathering

D. Asteroids hitting the Earth

EXPLANATION:

A. Volcanoes are formed by eruptions of lava and ash when molten magma rises through cracks in the Earth's crust. These cracks are caused by increased pressure in the earth leading to plate movement which forces molten rock to exploded into the air. Earthquake is the violent movement of the Earth's crust.

B. Erosion and Weathering also causes Earth transformation in some sense. It's the gradual removal of the topmost layer of the Earth's crust and however, the gradual wearing of rocks (that serves as peg for the earth) overtime can cause shift of the Earth's crust.

D. Asteroids are small rocky structure that moves around the sun, which can trigger earthquakes, hurricanes and tsunamis due to the increase in kinetic energy when it hit the land or water.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.
