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.
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.
Materials that allow convection to take place are usually fluids or gases, as they can easily move and transfer heat through the process of convection. Solids can also participate in convection to a lesser extent, especially if they have some degree of flexibility or ability to transmit heat through them. In general, materials that can move or flow are more likely to enable convection.

No, current scientific understanding states that fertilization of an egg by a sperm is required for human reproduction. However, in vitro fertilization techniques do exist that can enable conception without sexual intercourse.

The change from negative to positive in an alternating current indicates a switch in direction of electron flow. This occurs when the flow of electrical charge in a circuit reverses periodically, creating oscillations. These changes in polarity enable the efficient transmission of electricity through power grids and enable devices to operate.
