ASSIGNMENT ON OCEAN CURRENTS

Answer all questions

1. Draw a table similar to the one below to summarize the characteristics of cold and warm ocean currents.

2. Read the text below on the effects of cold ocean currents on the climate of the surrounding areas and do the tasks that follow.

Cold ocean currents have several effects on the climate of the adjacent coastal areas. They lower the temperature of adjacent land masses; result in low humidity in atmosphere as a result of low evaporation rates.

They also result in low cloud cover because of limited water vapour which would condense to form clouds. This is because cold ocean currents bring about low temperature conditions. Cold ocean current lead to low rainfall and desert conditions in adjacent areas.

Furthermore, these ocean currents lead to fog when warm air passes over a cold water surface. This leads to cooling of water vapor in the warm air which results in the formation of advection fog.

1. Suggest areas around the world where each of the effects explained in the text occurs. Give reasons to support your response.

2. Explain how the effects of cold ocean currents might affect human activities in coastal areas and the adjacent lands.
