Answer:
Ocean currents!!
Explanation:
The Oceans of the earth transfer heat from one location to another via massive ocean currents. These currents are like river flowing across the vastness of Earth, bringing warm water from the equator up towards higher latitudes, and cooler water down towards the equator.
Answer:
Positron emission
Explanation:
Positron emission involves the conversion of a proton to a neutron. This process increases the mass number of the daughter nucleus by 1 while its atomic number remains the same. The new neutron increases the number of neutrons present in the daughter nucleus hence the process increases the N/P ratio.
A positron is usually ejected in the process together with an anti-neutrino to balance the spins.
Answer: The nuclear equation is 
.
Explanation:
A nuclear reaction in which a heavy particle splits into another particle along with release of energy is called a nuclear fission reaction.
For example,
Here, energy is radiated in the form of gamma radiation.
Thus, we can conclude that the nuclear equation is .
