What is the type of rock that are formed from pre-existing rocks or pieces of once-living organisms ?
Igneous Rock
Sedimentary rock
Molten rock
Metamorphic rock
What are the three main types of rocks?
Sedimentary, volcanic, and crystalline
Metamorphic, volcanic, and sedimentary
Igneous, sedimentary, and metamorphic
Igneous, volcanic, and sedimentary
How are igneous rocks formed?
Through the solidification and cooling of magma or lava.
Through the evaporation of water.
Through erosion and weathering of existing rocks.
By the compression of sedimentary rocks.
Explain the concept of rock cycle.
The rock cycle involves only one type of rock
The rock cycle is a continuous process of rock formation, breakdown, and reformation involving igneous, sedimentary, and metamorphic rocks.
The rock cycle is a linear process with no recycling of rocks
The rock cycle does not involve any natural processes
How are metamorphic rocks formed?
By volcanic activity
By erosion and weathering
Heat and pressure acting on existing rocks
By sedimentation and compaction
