Flashcards in Aquatic Biomes And Fluid Dynamic Deck (27):
The ability or tendency to float in water or air and some other fluid
The centerfold of the immersed part of a ship or other floating body
Center of buoyancy
an upward force exerted by a fluid that opposes the weight of an immersed object
Net buoyant force
The moving of something from its place or position
A steep temperature gradient in a body of water such as a lake, marked by a layer above and below which the water is at different temps
What are the characteristics of aquatic ecosystems?
Temp, salinity, oxygen, nutrients and sunlight
What are the 3 types of organisms found in aquatic ecosystems?
Phytoplankton , nekton, benthos
Near the shore
Near the bottom
What 2 seasons does lakes turnover?
Spring and autumn
Areas saturated with water during part of the year
Which biome is the most diverse ?
What is the salinity of the ocean
What is the salinity of freshwater?
Pressure applied to a fluid in a closed container is equally applied to all parts of the fluid and the container
How does pascals principle apply to water??
The transfer of energy by the motion of a liquid or gas; think convection oven,
it blows hot air around the oven to cook the food more quickly
When gravitational force is greater than buoyant force what will happen?
The object will sink
When the gravitational force is less then buoyant force what will happen?
The object will float
When the gravitational force is equal to the buoyant force what will happen
It will neither sink nor float
Will buoyant force increase or decrease one more of the volume of an object is underwater?
Why is buoyant force and upward force not horizontal
Because it opposes gravity which is an downward force
The buoyant force is equal to the weight of the displaced water
As it contracted the plates and the fish sinks as it relaxes to fill with oxygen and causes of fish to become more buoyant
The pressure of a fluid (gas or liquid) as the fluid velocity increases
Which animal in the ocean is most affected by the Bernoulli's principal?
The shark, it becomes less boy it when it stops moving
