Most of the moss leaves lack Lignified cuticle, which is a subject of the drying out
The solubility of gas in water is inversely proportional to the temperature. That means cool waters can hold more gases than hot waters. So when the oceans continue to warm all the green--houses gases present in oceanic waters will be released into to the atmosphere. This would further lead to the heating up of the planet. The global climate would keep changing and the temperature of the planet would increase further. Therefore, when the oceans continue to warm the amount of green-house gases cannot be sequestered by the oceans (as the temperatures are high) and so this would further enhance the greenhouse effect.
Kinetic energy due to the movement
Balance each one by adding electrons to make the charges on both sides the same:
Sn--> Sn2+ + 2 e-
Ag+ + 1 e- --> Ag
Now, you have to have the same number of electrons in the two half-reactions, so multiply the second one by 2 to get:
2 Ag+ + 2 e- --> 2 Ag
Now, just add the two half reactions together, cancelling anything that's the same on both sides:
2 Ag+ + Sn --> Sn2+ + 2 Ag
And you're done.
