Convection always occurs in what two forms?
Convection typically occurs in two forms: natural convection, driven by buoyancy forces due to temperature differences, and forced convection, driven by external factors like fans or pumps. Natural convection occurs in fluids (liquids and gases) due to density variations caused by temperature gradients, while forced convection involves the use of mechanical devices to circulate the fluid.
What force caused by two things rubbing together?
The force caused by two things rubbing together is called friction. Friction is a resistance force that acts in the opposite direction of the motion between the two surfaces in contact. It is caused by the microscopic irregularities on the surfaces interacting with each other.
What are the different types of convection?
The three main types of convection are natural convection, forced convection, and mixed convection. Natural convection occurs due to density differences caused by temperature variations. Forced convection involves the use of external means like fans or pumps to enhance fluid movement. Mixed convection combines both natural and forced convection mechanisms.
What is a word for the air currents caused by temperature differences?
The word is "convection."
How do things gain heat?
Things gain heat through the process of heat transfer, which occurs when there is a temperature difference between two objects or systems. Heat can be transferred through conduction, convection, or radiation, and is typically caused by the movement of particles within the material.
What are two evidence of solar convection?
Two pieces of evidence for solar convection are the presence of granules on the solar surface, which are small convection cells visible in the photosphere, and solar oscillations caused by the motion of convection currents beneath the surface, which can be measured through helioseismology.

Most of the heating of the troposphere is caused by?
Convection
Is convection currents caused by the heat of the core?

Asssasssin crees
What is forced convection?
Convection caused by frontal or orographic lifting, or converging surface winds.
Where does convection happen?
Convection refers to the transfer of heat energy by the motion of a fluid such as air or water caused by differences in temperature within the fluid. Therefore convection happens wherever there is a fluid with a temperature gradient. This means that convection is happening continuously in the air around us and in bodies of water. A car heater and a convection oven are also considered to transfer heat by convection, but this is using the term liberally since the movement of the fluid (air) in these two cases is caused by a fan, not temperature gradient. So, while not perhaps being absolutely accurate examples of convection, still the heat is transferred through fluid motion.
