10 Questions
What is the term for rocks that form out of magma and lava from the interior of the earth?
Primary rocks
How are igneous rocks classified?
Based on texture
What is the process that transforms deposits into sedimentary rocks?
Compaction
Which type of rock is formed by the exposure of rocks on the earth's surface to denudational agents, followed by transport and deposition?
Sedimentary rocks
What is the process by which already consolidated rocks undergo recrystallisation and reorganization within original rocks?
Metamorphism
Which type of metamorphism occurs when rocks come in contact with hot intruding magma and lava, leading to re-crystallization under high temperatures?
Contact metamorphism
What refers to the arrangement of mineral grains or structural features in a parallel alignment, giving the rock a layered or banded appearance?
Foliation
Which type of rocks undergo recrystallization due to deformation caused by tectonic shearing together with high temperature or pressure or both?
Metamorphic rocks
In which type of rock, the layer of deposits retain their characteristics even after lithification, leading to the presence of layers varying in thickness?
Sedimentary rocks
Under what conditions do mechanically formed sedimentary rocks like sandstone, shale, etc. form?
Through mechanical weathering and erosion
Learn about the three main types of rocks based on their mode of formation: Igneous, Sedimentary, and Metamorphic. Understand how Igneous rocks form from magma and lava, and the process of cooling and solidification.
