Question

metamorphic rocks book pages 124 - 127
if the statement is true, write true. if the statement is false, change the underlined word or words to make the statement true.

1. ______ metamorphic rocks are foliated if their mineral grains are arranged randomly. p 126
2. ______ marble is often used in sculpture because its even color allows it to be carved into complex and detailed shapes. p 127
3. ______ heat and pressure change the sedimentary rock shale into slate. p 126
4. ______ metamorphic rock can form out of other metamorphic rock. p 125
5. ______ the deeper a rock is buried in the crust, the greater the pressure on that rock. p 125

fill in the blank to complete each statement.

Explanation:

Question 1

Foliated metamorphic rocks have mineral grains arranged in parallel layers or bands, not randomly. Non - foliated rocks have randomly arranged grains. So we need to change "foliated" to "non - foliated".

Marble is used in sculpture mainly because of its texture (it is relatively soft and has a uniform texture) rather than its color. So we should change "color" to "texture".

Shale is a sedimentary rock, and under heat and pressure, it undergoes metamorphism to form slate. This statement is in line with the knowledge of metamorphic rock formation.

Answer:

false (change "foliated" to "non - foliated")
