valuable ore deposits and gem crystals are often associated with a. oceansb. oil depositsc. thin crustal areasd. igneous intrusionswhich of the following shows a possible sequence that leads to the formation of sedimentary rocks? a. squeezing, heating, bending, foldingb. rising, weathering, erosionc. weathering deposition, compaction, cementationd. melting, cooling, crystallizationplz : )

For the first question:
Valuable ore deposits and gem crystals are often associated with igneous intrusions. So for this question the correct option is option “d”. An example like the Pegmatite’s, which are a form of igneous intrusions, is responsible for the creation of variety of gems like topaz and tourmaline.
For the second question:
For this specific question, option “c” seems to be the correct option. Weathering, deposition, compaction, cementation are the possible sequence that leads to the formation of sedimentary rocks.

Ithink it’s one of those things that you put the object on

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
