Answer: The heat source for Earth’s atmosphere and oceans is the sun, which heats from above instead of below.
Explanation:
In the experiment, the source of heat is the burner below the pot. On Earth this is completely different as the source of the heat on Earth is the Sun which heats us from above instead of below.
The Convection currents still flow in the same direction however because as the sun heats air particles on Earth's surface, they rise but then cool as they keep going up. This makes them go back down where they are then heated up again.
Answer:
E = 4 × 10⁻¹⁹ J
Explanation:
It is given that,
Wavelength = 510 nm
Frequency = 
We need to find the approximate energy of one photon of this light. The formula for the energy of a photon is given by :

or
E = 4 × 10⁻¹⁹ J
Hence, the correct option is (d).
