Question

Your sister had gone camping in Uttarakhand. She was fascinated with the smooth striated rocks she had collected. What type of rocks had she brought home with her?

पर्याय

• Igneous rocks

• Sedimentary rocks

• Metamorphic rocks

• Both Igneous rocks and Metamorphic rocks

Answer 1

Metamorphic rocks

Explanation:

Metamorphic rocks often display smooth, striated, or banded textures because they have been transformed under intense heat and pressure. This process causes the minerals within the rock to realign into layers or bands, giving them a foliated or striated appearance. In regions like Uttarakhand, where there is significant geological activity, such metamorphic rocks are common. So, the smooth, striated rocks your sister collected are best identified as metamorphic rocks.
