Similarities between glacier and geyser

The correct answer is:

The only similarity is that they are both glacier and geyser made of water.

The explanation:

1- geyser:

A geyser is a natural phenomenon that features a gushing fountain of water and/or steam being emitted from a hole in the ground. Such eruptions often occur on a periodic basis

2- A glacier:

is a huge lump of water ice and nothing more. If a glacier melted fast enough it would become a river.

So, both of them made of water.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
