What happens during atmospheric convections?
Warm air rises, and cool air sinks.
What is convections purpose?
convections purpose it to "recycle" warm and cold air or materials
What happens to convections currents when the liguid or gas is no longer heated?
The conventional currents will continue until the temperature of the substance is equal to surrounding temp.
Why are radiation and conduction also convections example of method heat transfer?
It's "convection" (not convections),but those are the words used to describe the three methods of heat transfer.
Does convections currents produce the heat in the earths interior?
False.
Are winds examples of convection currents?
Winds are examples of convections currents
What is the mechanical layer of earth that has the most active convections currents?
The Earth's core.
What do convections do in the inner core and outer core?
They move the hot and colder parts around.
Which is part of the convections cycle in Earth's atmosphere?
hot, less dense air rises
What happens at the end of a cold current?
- The Greenland Current -The Kamchatka Current -The Labrador Current
What happens to current at resonant frequency?
Current is at maximum
What is the low point of a sound wave (rare fractions) where the lowest air pressure occurs?
convections
