Answer:
The Atmosphere
Explanation:
1816 was a year without summer because the billions of tons of ash that was spewed blocked radiation preventing it from reaching the surface of the earth.
A volcano is a break in the crust of planetary bodies like Earth that allows gasses, volcanic ash, and hot lava to escape. Volcanos are one of the major factors that cause climate changes on Earth mostly because of their cooling effect.
The ash, gasses and lava usually escape to the atmospheric layer of the earth with their cooling effect. And they cool the earth by blocking incoming solar radiation. This can go on for months or years depending on the components and severity of the eruption and can lead to "a year without summer" as witnessed in 1816.

Answer:
10 H atoms combine with 5 oxygen to form 5 water molecules.
Explanation:
those substances which having low boiling point or low melting point such as water they form covalent bond.
Covalent bonds form between non-metal atoms. Each bond consists of a shared pair of electrons, and is very strong. Simple molecular substances and giant covalent structures have different properties.
You should consider how much you will eat, what materials you will use during the trip, how many days you the trip would last, how to budget what you can ideally bring without being overloaded, and what emergency stuff you need to bring, just in case something gets out of hand.
