Question

metamorphic rocks are often dash a dash due to the great effect of heat and pressure​

Answer 1

introduction

first you have to know what is metamorphic rocks Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form". The original rock is subjected to heat and pressure, causing profound physical or chemical change. The protolith may be a sedimentary, igneous, or existing metamorphic rock.

explanation

Metamorphism is the addition of heat and/or pressure to existing rocks, which causes them to change physically and/or chemically so that they become a new rock. Metamorphic rocks may change so much that they may not resemble the original rock.

please say thankyou if you like my hard work

Answer 2

Metamorphic rocks are often changed physically and chemically due to the great effect of heat and pressure.

How rocks are changed?

• The changes occur in metamorphic rock when pressure is above 200°C
• The pressure is high when the rocks are burning
• The metamorphic rocks get burned due to the tectonic process
• When the pressure changes then the rocks are changed chemically
• The texture and appearance of the rocks get change due to heat and pressure
• When the temperature is above 320°C then the rocks become less hydrous
