UNIT III - EARTH MOVEMENTS AND THEIR EFFECTS

Specific Objectives

Students should be able to:

 

Explanatory notes
Suggested Practical Activities

1

Explain the formation of land and sea breezes;

 

Consideration that hot air rises and cold air sinks.

Conduct convection experiments.

2

Describe the various types of air masses

 

Air masses affecting the Caribbean;

the spread of pollutants by moving air masses;

radioactive fall-out, volcanic dust, industrial waste, Sahara dust, landfill fumes

Demonstrate by using- telephones; springs; lamps; shock absorbers in vehicles; batteries; electric motor

3

Distinguish between the four types of local fronts

Consider how they effect the weather

 

Keep records of local fronts (cold, warm, stationary, occluded) obtained form weather forecasts, relate them to weather patterns observed;

Collect records of hurricanes in the Caribbean to trace their paths on weather maps

4

 

Describe the characteristics of a cyclonic storm, particularly a hurricane

Consider conservation of linear momentum

(refer to vehicular collision)

Use the momentum conservation principle to predict the outcomes of collision;

use simple qualitative trolley experiments

 

5. Describe tidal waves and how they are formed

Underwater landslides, volcanoes and earthquake:

describe a tsunami and how it is formed;

 
6. Discuss the causes of the different types of volcanic eruptions The ecological consequences of volcanoes in the short and long term Use models to show  volcanic eruptions
7. Describe the different types of seismic waves The function of a seismograph  
8. Discuss the relationship between earthquakes and volcanoes   Plot occurrences of earthquakes and volcanic activity on a map of the Caribbean, Keep records of tidal patterns
9. Describe how tides are formed Some effects of tides

Study of plant and animal life on seashores or river banks with respect to tidal patterns.

Keep records of tidal patterns.
