Once heat from the Sun penetrates the Earth's atmosphere, the heat is circulated as warm air rises and cold air sinks. What is this process called?1. convection
2. radiation
3. reflection
4. conduction

Answers

Heat from the sun is radiated to the surface of earth. The circulation of heat through the atmosphere of earth is taken place by the process called convection.

What is heat transfer?

Heat will transfer from regions of greater heat to regions of less heat. The mode of heat transfer in different states of matter. The heat transfer mode in solids is called conduction.

The closely packed molecules in solids transfers the heat throughout the chain of the molecules by conduction. The heat transfer mode in fluids that's in air and liquids is called convection, where the hotest molecules from the ground rises to the top making the molecules in its path hot.

Radiation is the heat transfer mode in vacuum. Electromagnetic waves and heat energy are transferred to surface of earth by radiation. Therefore, the radiated heat energy is circulated throughout the earth's atmosphere is convection.

Once heat from the sun penetrate the Earths atmosphere, the heat is circulated as warm air rises and cold air sinks,this process is called convection Convection can be demonstrated by placing a heat source {cooker} at the side of a glass full of a liquid, and observing the changes in temperature in the glass caused by the warmer fluid moving into cooler areas

Answers

well you could sort it out based on color you could stain and that uses size you could get a magnet if you want to seperate out iron or something which uses electro magnetism and if it is a liquid you could let it stand till it seperates using density

Which of the following is formed at a collision zone?Continental rift valleyVolcanic island chainMountain rangeDeep-ocean trench

Answers

all these landforms can be found at collision zones. they depend on which type of collision, though. there are oceanic-oceanic collision, oceanic-continental collisions, and continental-oceanic collisions. oceanic plates are dense and small, and continental plates are massive, but heavy. i hope this answer helped you.
