true
false
question 2 (2 points)
listen
metamorphic rocks require both heat and pressure to form.
true
false

Explanation:

• Question 1: Marble is a metamorphic rock formed from limestone (not sandstone). Limestone is a sedimentary rock. When limestone is subjected to heat and pressure, it recrystallizes to form marble.
• Question 2: Metamorphic rocks form when existing rocks (igneous, sedimentary, or other metamorphic rocks) are subjected to heat (from magma or geothermal gradients) and pressure (due to tectonic forces like mountain - building or burial). This causes changes in mineralogy, texture, and sometimes chemical composition.

Answer:

• Question 1: B. False
• Question 2: A. True
