How do birds use convection currents to fly?
Birds use convection by using convection currents the heat will rise as a draft and then birds can ride the draft to reach higher altitudes.
Under the same conditions of temperature and pressure three different samples of the same uniform substance will have the same?
Density reason is that the density of a uniform material is constant Density is independent of the size and shape of the sample.
Do convection currents always affect the same way?
no
Surface currents are set in motion by the?
convection currents are set into motion by heat.without heat the convection currents would stop when all the material reaches the same temperature.
Can a copper penny and a large copper bell have the same density and why or why not?
Density is an intensive property, not dependent from the size of an object.Density is the ratio between mass and volume.If the coin and the bell have the same chemical composition the density is equivalent.
What is the differencein pressure between salt water and fresh water at different depths?
Currents and thermal gradients aside, salt water is slightly more dense than fresh water, so (at the same depth, for the same temperature) the pressure in salt water will be creater than for fresh water. The difference in pressure will be (pressure in fresh water) x (density of salt water/density of fresh).
How do surface currents differ from density currents?
The same thing! Deep Currents Occur when the density of the water increases. Density is based on two main things it is the civility is how much salt and other solids are in it and it is also the temperature of the water.The lower the temperature the lower the dense the water becomes. The denser the water the more it was to go down. The less dense the water wants to rise. The temperature is what causes the dense. Deep current:A streamline movement of ocean water far below the surface.
What happens if your density is lighter than the density of air?
you will start to float upwards in the atmosphere. The density of air decreases as you go higher in the atmosphere. You will stop going upwards when you reach a height where the air density is the same as your density.
What two forces primarily drive the ocean currents?
From apex: Density Differences in water and Energy transfer from winds. Hope it's the same for you
How many feet are in depths?
The same number as there are feet in heights. Depths is not a specific measure.
Why do jellyfish float instead of sink?
when jellyfish reach adulthood they are about 95% water, so they are about the same density as water.
How does the density of a body and that of a liquid determine that whether the body will float or sink into that liquid?
If the density of the solid body is greater than the density of the liquid the bodywill sink. If the density of the liquid is greater than the density of the solid thebody will float.If the solid and the liquid have the same density, the solid body can be any whereinside the liquid and may move following currents if they exist in the liquid.Read more:How_does_the_density_of_a_body_and_that_of_a_liquid_determine_that_whether_the_body_will_float_or_sink_into_that_liquid
Why does water at the bottom of frozen lakes stay the same temperature?
pressure of the depths are the same
The rising and falling of heated gas is called?
Warm gas will rise above colder gas of the same type, as it will have a lower density, cooler gas will fall and take its place. These are convection currents.
Are the oxygen levels same at different depths of water?
no the water levels those not stead the same
How are convection currents in water like convection currents in earths mantle?
They both are the same because they are currents that move like waves
What are tide currents?
Tidal currents are not quite the same thing as tides. Tidal currents are horizontal movements of water caused by the tides.
