Convection currents are created by temperature differences in the Earth's atmosphere and oceans. Warm air or water rises, carrying energy with it, while cooler air or water sinks. This continuous cycle of rising and sinking helps transport heat energy around the globe, contributing to the redistribution of heat and maintaining the Earth's climate system.

What kind of transport across a membrane does not require energy?
Passive transport does not require energy as it allows molecules to move across a membrane from an area of higher concentration to an area of lower concentration. Examples of passive transport include diffusion, osmosis, and facilitated diffusion.
The movement of matter due to differences in density and the transfer of energy that results from this movement is called?
The movement of matter due to differences in density and the transfer of energy that results from this movement is called convection.
What happen as thermal energy is transferred from the core to the mantle?
As thermal energy is transferred from the core to the mantle, it causes convection currents in the mantle. These currents are responsible for the movement of tectonic plates at the Earth's surface. This movement leads to processes such as seafloor spreading, subduction, and volcanic activity.
What is the transfer of thermal energy by movement of heated matter?
Convection is the transfer of thermal energy by the movement of heated matter, such as air or water. This process occurs as warmer, less dense material rises and cooler, denser material sinks, creating a convection current that transfers heat.
How do air and water transfer energy?
Air transfers energy through convection, where warmer air rises and cooler air sinks, creating air currents that transport energy. Water transfers energy through convection as well, but its higher density allows for greater heat retention and storage, making it a more efficient energy transfer medium.
Is a convection current the same as a convection?
Yes. Convection is a type of energy and a convection current is, well, the phrase for its currents. So yeah, convection and convection current are the same.
What are the three processes that transport energy?
It is radiation, convection, and conduction
What type of energy transport is just below the suns photosphere?
The energy transport just below the sun's photosphere is mainly by convection. Convection is the process where hot material rises, cools down, and then sinks back down to be reheated, creating a cycle of energy transfer. This convection zone helps move heat from the sun's core to its surface.
What does heat and energy have to do with convection?
A convection current is when hot air rises, and cool air fall, creating convection.~Britney, 7th
Does convection occur in the core of a star?
Yes, convection does occur in the core of a star. In the core, convection helps transport energy from the inner regions to the surface of the star. This process is crucial for mixing the stellar material and maintaining the overall stability and temperature balance of the star.
Give a real life analogy to diffrentiate between passive transport?
Passive transport is like a door swinging freely on its hinges allowing people to move in and out without requiring energy. For example, osmosis is a passive transport process where water molecules move across a semi-permeable membrane from an area of high concentration to low concentration without the cell using energy.
What kind of transport across membrane does not require energy?
Ghh
Is convection current kinetic energy before transferring?
Yes, convection currents involve the transfer of heat energy through the movement of fluids such as air or water. The kinetic energy of the fluid particles increases due to the heat transfer, creating the convection currents. So, convection currents involve the conversion of thermal energy into kinetic energy as the fluid moves.
What is it called when sugars pass across the membrane that requires the use of energy?
active transport
What kind of transport across a membrane does not require energy?
Passive transport does not require energy as it allows molecules to move across a membrane from an area of higher concentration to an area of lower concentration. Examples of passive transport include diffusion, osmosis, and facilitated diffusion.
What ways of moving molecules across a membrane requires energy?
Active transport requires energy to move molecules across a membrane against their concentration gradient. This process is facilitated by specific carrier proteins embedded in the membrane that use energy, usually in the form of ATP, to transport molecules.
What is the process of moving materials across membrane with energy?
active transport
