Which of the following does NOT match the landform with the process that created it? A glacier is a body of dense ice that forms when icebergs melt. A sinkhole is a result of chemical weathering processes from rainwater and groundwater. A coastline is a deposit of sediment that originates in the mountains and is transported by rivers. A delta is a flat area of land where rivers and streams flow into a non-flowing or slow-flowing larger body 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.

i think its 100.

hope this !
