The two basic geologic processes which contributed to the formation of folded mountain ranges like in Glacier National Park include:
- Folding and breaking of sedimentary rocks.
<h3>What is Erosion?</h3>
This is a geologic process which involve materials in the earth being washed away and transported to other parts by water, wind etc.
In the case of Glacier National Park, ice erodes the mountain thereby resulting in the folding of the sedimentary rocks.

Halogen element, any of the six nonmetallic elements that constitute Group 17 (Group VIIa) of the periodic table. The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts). They were given the name halogen, from the Greek roots hal- (“salt”) and -gen (“to produce”), because they all produce sodium salts of similar properties, of which sodium chloride—table salt, or halite—is best known.
Answer:
a. Tellurium
b. Rubidium
c. Argon
d. Astatine
Explanation:
a. An element of the same family as oxygen corresponds to group 16 or 6A, its most stable ion is -2, therefore if the ion has 54 electrons the neutral element should have 52 electrons and also 52 protons. Tellurium
b. The ions from alkali metals are +1, therefore the neutral elements have 1 more electron and proton, since the ion has 36 electrons the neutral element has 37. Rubidium
c. This is direct, look for the element with Z = 18. Argon
d. This is also direct, look for the element with Z = 85. Astatine
The balanced equation :
LiI(aq) + AgNO₃(aq) --> AgI(s) + LiNO₃(aq)
<h3>Further explanation</h3>
Given
Word equation
Required
Balanced equation
Solution
There are 3 ways to express a chemical equation:
- word equation
- skeleton equation
- balanced equation
Skeleton equation for reaction above :
LiI(aq) + AgNO₃(aq) ⇒ AgI(s) + LiNO₃(aq)
If we look at this reaction, all the cations and anions have a charge of 1 (+1 or -1) so the balanced reaction between the skeleton equation and the balanced equation is the same
