Flash Cards
(26 cards)
Traction
Large particles like boulders are pushed along the sea/river bed by the force of the water
Saltation
Pebble sized particles are bounced along the river/sea bed due to the force of the water
Suspension
Small particles like silt and clay are carried along in the water
Solution
Soluble material e.g. like stone dissolve in the water and are carried along the river/sea
Irrigation
Artificially watering plants/crops instead of relaying on rain
Transpiration
When moisture from the plants is given off into the atmosphere
Hydraulic action (river)
Hydraulic action is the force of the water against the river banks and bed, often trapping air in cracks and causing the rock to break apart.
Abrasion (river)
Abrasion Abrasion involves pebbles and other material carried by the river scraping and wearing away the riverbed and banks.
Corrosion (river)
Corrosion occurs when water, especially slightly acidic water, dissolves certain types of rocks, like limestone.
Attrition (river)
Attrition is the grinding and breaking down of rock particles as they collide with each other(becoming more round).
What are the four rain forest layers
emergent,
canopy,
understory,
forest floor.
Emergent layer characteristics
uppermost layer, where the tallest trees reach.receives the most direct sunlight and experiences the hottest, most windy, and wettest conditions. Animals like birds, small mammals, and some insects are found here.
Canopy characteristics
continuous layer of tree tops, dense and providing shade.
Under story
The area below the canopy, receiving less sunlight.
Forest floor
The ground layer is dark and damp with a thick layer of leaf litter.
Tributary
Little stream going into the main channel of a river (upper course)
Discharge
Amount of water flowing through a river
Food chain
Shows what eats what in a biological community
Food webs
Show how several food chains overlap each other
What do some consumers use their producers as
A habitat
What does Interdependence in an ecosystem mean
When all the difference parts of an ecosystem depend on each other
Why does decomposition happen quickly In a tropical rainforest?
Because of the hot humid temperature.
Biodiversity statistic for Rainforest
Rainforests cover 6% of earth’s surface area, however they house up to 50% of the world’s animal and plant species
