70 million years ago |
|

It was 25 million years ago |
|
What happened during the 2nd mountain building period |
The lesser Antilles formed the inner arch of the archipelago
Mountains were uplifted such as Rockies,Andes and Hima layers |

The greater Antilles is located north of lesser Antilles and also greater Antilles has more countries |
|
Name the tectonic plates |
They are divergent,transform and convergent |
|
Describe the three(3) plates |
Divergent is when two plates move away from each other. Convergent is when two plates move towards each other. Transform is when two plates slide past each other. |
|
What is evaporation,condensation and precipitation |
Evaporation is when liquid turns to water vapor. Condensation is the process in which water vapour changes in to liquid state. Precipitation is the result of air rising and cooling. when saturation level is attain condensation takes place and rain falls. |
|
Where does land breeze blow from |
Land breeze blows from land to sea. |
|
Where does sea breeze blow |
Sea breeze blow from sea to land |
|
What is pressure |
Pressure is a force or weight area |
|
Pressure is influence by: |
1.temperature 2 earth resolution 3. Altitude |
|
What is natural vegetation |
This was when crops grow naturally |
|
Types of vegetation are |
Mangrove,montane,evergreen ,rainforest |
|
What were the characteristics of Stevenson screen |
It is painted white to protect instrument from direct sunlight
It stands 1.2 meters off the ground It roof is slanted to avoid stagnation and accumulation of rain water
|
|
What are some the instruments the Stevenson screen houses |
Thermograph,hygrometer,barometer,thermometer,dewcell |
|
What are the factors influencing vegetation |
Rainfall Soil fertility Topography Light Man |
|
List characteristics of mangrove vegetation |
It grows along coastal area They are hydrophytic plants |
|
List characteristics of semi deciduous woodland |
They develop on coastal lowlands. Trees shed leaves to conserve water. Vegetation consist of tall shrubs,cactus and woodland. |
|
List characteristics of rainforest |
Founded in high mountainous areas. Trees form canopy at the top. Roots of trees are shallow. |
|
List characteristics of months e forest |
Trees are covered in moss and lichens. Trees are smaller than those found at lowlands. |
|
List characteristics of elfin woodland |
Tress are stunted. Located on high peaks. Flowers are abundant. |
|
What is the Stevenson screen |
It is a small wooden structure found at weather stations. |
|
What is weather |
Weather is the condition of the atmosphere of a special place for a short period of time |
|
What is climate |
Climate is average elements of weather condition of a sizeable area for long periods |
|
List and describe the ways in which land heats of faster than water. |
1)Land is darker .land absorbs more solar radiation than water due to the the fact that most land surfaces is darker than water. 2)land is stationary while water is in constant movement. 3)water reflects most radiation that reaches it's surface. |
|
List and describe factors affecting temperature.
|
1)Altitude When height increases temperature falls for every kilometer you go up temperature falls by 6.5° 2)latitude sun rays hit the earth vertically at the equator causing a major heating effect.As you move further away from the equator temperature falls. 3)distance from sea during the day the Earth heats up at air rises.winds blows in from the sea to replace the rising air,causing a cooling effect.places closer to the sea benefit from this. 4)ocean current When winds blow of a warm ocean current it raises the temperature of this wind thus when this wind passes over land it gives it a warming effect. 5)cloud cover it reduces the the amount of solar radiation that reaches the earth surface and the amount of earth radiation which leaves.
|
|
State the layers of the atmosphere from lowest to highest |
Troposphere, stratosphere, mesosphere, thermosphere, exosphere |
|
What is insolation |
Insolation is the process that takes place at the earth surface.the earth receives solar energy in the form of short waves. |
|
Why are the lower layers of the atmosphere warmer |
It is warmer because heating takes place closer to the earth surface. |
|
Describe the way in which solar radiation is distributed |
46% is receive by the earth surface,40% is reflected by clouds,dust gasses and other particles in the atmosphere,14 is reflected directly by the atmosphere. |
|
Where is the rain shadow located in st.vincent |
It is located on the eastern side. |
|
List and describe the importance In agriculture |
1) agriculture contributes to the gross domestic product(g-d-p) and to export earnings. 2)employment:thousands of individual are employed in agriculture. 3)food security:farming provides a great deal of food locally reducing the need to rely upon food imports. 4) agriculture provides raw material to secondary industries such as food processing. |
|
What is a small scale farmer |
A small scale farmer is a farmer who grows variety of crops and rear livestock on the same plot of land. |
|
List characteristics of small scale farmers |
1) location Small scale farms are generally located in hilly areas because lowlands are occupy by housing and plantation. 2)Size of farms-these farms are usually smaller than 1.2 hectares. 3)Labour-family was the main type of labour management. 4)Tools-small farmers use Traditional tools such as Cutlass,hoe,and fork 5)farming practises |
|
What was mix cropping |
This is where you cultivated crops and rear animals on the same land |
|
What is contour ploughing |
This the farming practise of ploughing and planting crops across a slope following is elevation. |
|
What is terracing |
This is where humans transform a slope in two a series of flat surfaces,crops are then grown on these flat surfaces rather than slope to avoid them sliding. |
|
What is strip croping |
Strip cropping is the cultivation of different crops in which they are sown in alternate strips. |
|
What is crop rotation |
This is the farming practise of growing a series of different crops in the same area in sequence seasons |
|
What is crop fallowing |
This is a stage of crop rotation where you deliberately not used the land to raise crops |
|
List the ways in which small scale farmer market their produe |
1)small scale farmers retail their produce on road stalls near urban areas. 2)some sell to wholesalers. 3)some sell to trafficers who then sell them to regional markets. 4)some sell to venders who operated in central market. 5)some sold to supermarket,hotels and restaurants. |
|
List and describe problem faced by small scale farmers. |
1) small size -the small size limit the use of machinery. Which would have help in crop production. 2)lack of capital-farmers lack suffient money to purchase machinery, fertilizer and improve transport. 3)pest and diseases. 4)unpredictable weather conditions. 5)poor feeder roads-roads are often lacking access for farmers to bring out their produce. |
|
