The convection currents in air transfer heat 1 point Downwards Upwards Downwards as well as upwards Sideways
Answers
Answer:
upwards
Convection currents transfer heat from one place to another by mass motion of a fluid such as water, air or molten rock. The heat transfer function of convection currents drives the earth's ocean currents, atmospheric weather and geology.

I know only this
What are Convectional currents?
Convection currents are flowing fluid that is moving because there is a temperature or density difference within the material. Because particles within a solid are fixed in place, convection currents are seen only in gases and liquids. ... Convection is a heat transfer process
HEAT: ENERGY TRANSFER
What is the difference between heat and temperature?
How does a heater warm up a cold room?
Why can the Sun make us warm?
Why does my cold drink become warm?
Heating as a transfer of energy

In the last chapter we looked at thermal systems. The thermal energy of an object is the amount of energy it has inside of it, in other words, its internal energy. In a thermal system, thermal energy is transferred from one object to another. Heat is the transfer of thermal energy from a system to its surroundings or from one object to another. This transfer of energy is from the object at a higher temperature to the object at a lower temperature.
It is very important to know that, in science, heat and temperature are not the same thing.
Heat is the transfer of thermal energy from a system to its surroundings or from one object to another as a result of a difference in temperature. Heat is measured in joules (J). This is because heat is a transfer of energy.
Temperature is a measure of how hot or cold a substance feels and it is measured in degrees Celsius (°C). Temperature is a measure of the average kinetic energy of the particles in an object or system. We use a thermometer to measure the temperature of an object or substance.

Heat is the transfer of energy. During energy transfer, the energy moves from the hotter object to the colder object. This means that the hotter object will cool down and the colder object will warm up. The energy transfer will continue until both objects are at the same temperature.
There are 3 ways in which thermal energy can be transferred from one object/substance to another, or from a system to its surroundings:
Conduction
Convection
Radiation
