Answer:
Ore is a deposit in Earth's crust of one or more valuable minerals. The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron.

Answer:
Na < K < S < Be
Explanation:
Let's work with NA and molar mass of each.
- 1.5 mol of K → should be converted to atoms ( mol . NA)
1.5 mol . 6.02×10²³ = 9.03×10²³ atoms of K
- 64 g of S → should be converted to mol (mass / molar mass). Then, into atoms. (mol . NA)
64 g / 32.06 g/m = 1.99 mol
1.99 m . 6.02×10²³ = 1.20×10²⁴ atoms of S
- 20 g of Be → should be converted to mol (mass / molar mass). Then, into atoms. (mol . NA)
20 g / 9.01 g/m = 2.22 moles
2.22 m . 6.02×10²³ = 1.33×10²⁴ atoms of Be
- 25 g of Na → should be converted to mol (mass / molar mass). Then, into atoms. (mol . NA)
25 g / 23 g/m = 1.08 moles
1.08 m . 6.02×10²³ = 6.54×10²³ atoms of Na
The lithosphere (under the tectonic plates) is semifluid, allowing for the plates above to move over it, causing earthquakes, and essentially continental drift.
