What happens when horizontal stress acts upon a rock?
by differential movements on one set of parallel planes which results in internal rotation of.
What kind of rock is likely to form where the heat the granitic magma is conducted to the limestone country rock?
The rock which will form will be marble because the limestone undergoes metamorphosis (partial recrystallisation).
What is a force that changes a rock's shape or form?
Stress
How the direction of stress applied affects the arrangement of minerals in a metamorphic rock?
The direction of stress applied can affect the alignment of minerals in a metamorphic rock. When stress is applied in a particular direction, minerals tend to align perpendicular to the direction of stress, resulting in foliation if the rock undergoes sufficient pressure. This alignment can create layers of minerals within the rock, giving it a distinct texture and cleavage.
What is a fold where both ends of the rock layer are are horizontal?
A fold where both ends of the rock layer are horizontal is known as a "recumbent fold." In this type of fold, the rock layers are bent over so that the axial plane is nearly horizontal, causing the limbs of the fold to lie parallel to the ground. Recumbent folds typically form under intense compressional forces, often associated with mountain-building events. They can indicate significant geological stress and deformation in the Earth's crust.
What type of feature can form when magma hardens between horizontal layers of rock?
A concordant intrusive igneous feature like a sill can form when magma hardens between horizontal layers of rock. Sills are tabular bodies that are parallel to the surrounding rock layers.
What type of feature can form when magma hardens horizontal layers of rock?
Sill (D)
What is the name of the original rock metamorphic rock?
The original rock that undergoes metamorphism to form a metamorphic rock is called a protolith or parent rock.
What is it called when a rock changes?
Metamorphism....A metamorphic rock is a rock formed when it undergoes chemical reactions,tremendous heat and great pressure to form a new kind of rock from an existing one.
When limestone undergoes metamorphism it produces which metamorphic rock?
When limestone undergoes metamorphism, it produces the metamorphic rock called marble. This process involves recrystallization of the calcite mineral in limestone to form interlocking crystals of calcite in marble.
What type of rock is likely to form next when extrusive igneous rock is broken down by weathering?
Sedimentary rock is likely to form next when extrusive igneous rock is broken down by weathering. Weathering breaks down the igneous rock into sediment, which then undergoes compaction and cementation to form sedimentary rock over time.
When any type of rock undergoes weathering it usually forms this type of rock?
When any type of rock undergoes weathering, it usually forms sedimentary rock. Weathering breaks down existing rocks into smaller pieces that get deposited and compressed to form sedimentary rocks over time.
