Convection currents occur in many places- both liquids and gases. One example is the flow of magma beneath the surface of the lithosphere (crust), where magma is heated in the centre of the Earth, therefore rising to just beneath the crust, where it cools and then sinks back down towards the centre of the Earth in a repaeating cycle... Coincidentally, it is this motion that causes the movement of the Earth's tectonic plates worldwide, and is thus responsible for seismic and volcanic activity on a global scale.
Another word for convection is "circulation."
No, one thing hitting another is an example of convection, not conduction. Conduction is the transfer of heat between two objects that are in direct contact with each other, without any movement of the materials.
Yes, a lava lamp is an example of convection. The movement of the colorful wax inside the lamp is due to differences in temperature causing it to rise and fall, creating a convection current.
Boiling water in a pot where the hot water rises and cool water sinks is an example of natural convection. Using a convection oven where hot air circulates to cook food evenly is an example of forced convection.
Convection is the transfer of heat through a fluid (liquid or gas) by the movement of the fluid itself. An example of convection is when warm air rises near a heat source, such as a radiator, cools down as it moves away, and then sinks back to be heated again, creating a convection current.
Adhesion is a non-example of convection.

An example convection is write down your notes in class so you know what it is.
Convection
yes a hard boiled egg is an example of convection!!!
convection
Radiation
convection
Conduction, Convection and Radiation For example, for conduction you can use a boiling pot of water. For convection you can use a blender. For radiation you can use the sun or another one is your cell phone.
yes
The Gulf Stream is an example of convection current.
