How an hawk or eagle could use convection currents to soar upward without flapping its wings?
Current caused by the expansion of a liquid, solid, or gas as its temperature rises. The expanded material, being less dense, rises, while colder, denser material sinks. Material of neutral buoyancy moves laterally. Convection currents arise in the atmosphere above warm land masses or seas, giving rise to sea breezes and land breezes, respectively.

What property of the air has the most influence on convection currents?
Temperature is the property of air that has the most influence on convection currents. Warm air is less dense than cold air, causing it to rise and create upward convection currents. Conversely, cold air is denser and sinks, leading to downward convection currents.
How are convection currents influenced by weather?
Weather influences convection currents by affecting the temperature and moisture content of the air. Warmer air rises, creating upward convection currents, while cooler air sinks, leading to downward currents. Changes in weather like cold fronts, warm air masses, and moisture levels can all impact the strength and direction of convection currents.
Explain how convection takes place in the mantle?
Convection in the mantle occurs due to the heat generated from radioactive decay and the residual heat from the Earth's formation. This heat causes the mantle material to become less dense, leading to upward movement. As the material cools near the surface, it becomes denser and sinks back down, creating a circular motion of convection currents.
Add this to air to make it rise?
Adding heat to air will cause it to rise. As air heats up, it becomes less dense than the surrounding cooler air, resulting in upward movement known as convection. This process is what drives phenomena like thermals and creates upward air currents.
What force causes warm molten rock to move upward to the mantle?
The driving force for the upward movement of warm molten rock in the mantle is primarily buoyancy. As molten rock is less dense than the surrounding solid rock, it rises due to its buoyancy forces. Additionally, convective currents within the mantle, driven by heat from Earth's core, also play a role in the movement of molten rock.
How would a hawk soar upward without flapping its wings using convection currents?
A hawk can soar upward by riding on rising columns of warm air called thermals. The hawk positions itself in the thermal and uses the updraft of warm air to gain altitude without flapping its wings. By circling within the thermal, the hawk can maintain its altitude or climb higher as it rides the convection currents.
How a convection current can enable a hawk to soar upward without flapping its wings?
A hawk can soar upward without flapping its wings by utilizing convection currents, which are upward streams of warm air. As the sun heats the Earth's surface, the warm air rises, creating these currents. By gliding into these rising columns of warm air, the hawk can gain altitude effortlessly, conserving energy while maintaining flight. This technique allows it to travel long distances while searching for prey.
What direction do convection currents-move?
Convection currents move in upward direction
How do birds use convection currents to fly?
Birds use convection currents by taking advantage of rising warm air to gain altitude without constantly flapping their wings. By soaring in these upward air currents, birds can conserve energy and cover long distances while searching for food or migrating. They use their wings to adjust their position within the convection currents to stay aloft.
What property of the air has the most influence on convection currents?
Temperature is the property of air that has the most influence on convection currents. Warm air is less dense than cold air, causing it to rise and create upward convection currents. Conversely, cold air is denser and sinks, leading to downward convection currents.
How does a convection current enable a hawk or eagle to soar upward without flapping its wings?
A convection current is a mass of warm air moving upwards because it is less dense than the air around it. These currents are usually called "Thermals" and care capped at their top by a cumulus cloud. If a bird can find the rising column of air that is a thermal and circle round in it, the bird is carried aloft with the air, without the need to flap its wings.
The upward movement of warm air and the downward movement of cool air form?
The upward movement of warm air and the downward movement of cold air forms fluids.
What direction do convection currents move?
Convection currents move in a circular motion, where warmer, less dense material rises while cooler, denser material sinks. This creates a continual cycle of rising and sinking currents that transfer heat within a fluid like air or water.
Explain how a hawk or eagle can sometimes soar upward without flapping its wings?
the hawk is facing or soaring throught the sky. the wind is pushing it and so the hawk just soars. than it may have to keep going so it flaps its wings......You asked a great question and i am getting this answer out of a text book so this is a true answer. LOVE ONE ANOTHER AS ONE WOULD LOVE U
The upward movement of warm air and the downward movement of cool air form what?
The upward movement of warm air and the downward movement of cool air form convection currents. This process is a key factor in driving weather patterns and climate phenomena such as thunderstorms and ocean circulation.
What is an obstruction current?
an updraft caused by winds as they srtike such obstacles as mountains or cliffs and are deflected upward; used by soaring birds to gain altitude without flapping
What is a force that pushes the heated rock upward?
The force that pushes heated rock upward is typically convection currents in the mantle. As rock near the Earth's core heats up, it becomes less dense and rises towards the surface. This movement creates pressure that pushes the rock upward.
