Chapter 10, Problem 3LR

Summary Introduction

a.

Introduction:

The oceans are a vast body of water that covers the majority of the earth's surface. The land is occupied by lakes, seas, pond, and rivers but does not account for a very large proportion of water. The ocean water is constantly exposed to the radiation of the sun and experiences a high rate of evaporation.

Summary Introduction

b.

Introduction:

The temperature of the atmosphere is affected by various factors such as wind, precipitation, humidity, and solar radiation. The temperature of the ocean currents is influenced by humidity, wind speed, and evaporation rate.

Summary Introduction

c.

Introduction:

The climate of any region is the combination of rainfall, humidity, solar radiation, and wind experienced by that region over a longer period of time. The climate is distinguished into different classes based on Koppen classification.

Summary Introduction

d.

Introduction:

The oceans of the world are divided into the largest Pacific ocean, Atlantic Ocean, Antarctic or Southern and Indian ocean. The rest 29% of the area is covered by the landmasses that form the continents. The ocean water undergoes high and low tides due to the gravitational pull from sun and moon.

Summary Introduction

e.

Introduction:

The equator lies in the latitudes of 0° which faces immense heat from the sunlight. The subtropical and tropical areas do not experience harsh sunlight and lie in 30-60° latitude. The factors that affect the nature of seawater or ocean water are temperature and salinity. The latitudes also affect the tides that take place in the oceans.
