Part A
Estimate the number of moles of water in all the Earth's oceans.
Assume water covers 75% of the Earth to an average depth of 3
km.
Express your answer to one significant figures and include the
appropriate units.
Part B
Estimate the number of molecules of water in all the Earth's
oceans.
Express your answer using one significant figure.

Estimate the total force with which Earth's atmosphere pushes down on all the oceans of the planet. (The radius of Earth is 6.37 x 10° m, and atmospheric pressure sea level is 1.01x i0°N/㎡).

Suppose that Earth's polar ice caps melted and the water returned to the oceans, so that the oceans were deeper by about 11.4 m. What effect would this have on Earth's rotation? Make an estimate of the resulting change in the length of the day. (Concern has been expressed that warming of the atmosphere resulting from industrial pollution could cause the ice caps to melt.)

In a simple model of Earth's oceans, the upper layer of water that is well mixed by waves, wind, and heating by sunlight is about 500 m deep. This layer sits on a deeper layer of colder water beneath it. The area of the upper layer is about 3.60e+08 km2 and its average temperature is currently about 17 °C. Suppose that the temperature of this upper layer is increased to 19.2 °C. (a) By how much will the volume of...

Scientists predict that as atmospheric carbon dioxide levels increase, the pH of the oceans will drop. What is the best explanation for this hypothesis? As the pH of the ocean increases, more carbon dioxide is released into the atmosphere As the pH of the ocean decreases, more carbon dioxide is released into the atmosphere O Carbon dioxide combines with water to form a base Carbon dioxide combines with water to form an acid As the oceans warm, more water is...
