Understanding Rock Deformation

What is rock deformation?

• Rock deformation is the process of creating new rocks from magma.

• Rock deformation refers to the formation of sedimentary layers over time.

• Rock deformation is the process of weathering and erosion of rocks.

• Rock deformation is the alteration of rocks in response to stress, resulting in changes in shape or volume.

Explain the difference between folding and faulting.

• Folding is a process that occurs only in sedimentary rocks, while faulting can occur in any type of rock.

• Folding creates earthquakes, while faulting does not.

• Folding results in the formation of mountains, while faulting leads to the erosion of land.

• Folding involves bending of rock layers, while faulting involves breaking and displacement of rock layers.

What are the main types of folds in geology?

• Fault lines, shear zones, volcanic arcs

• Rift valleys, ocean trenches, mountain ranges

• Plate boundaries, sedimentary layers, metamorphic rocks

• Anticlines, synclines, monoclines, dome folds.

Describe how stress affects rock deformation.

• Stress only causes rocks to become more brittle.

• Stress has no impact on the physical properties of rocks.

• Rocks do not deform under any stress conditions.

• Stress causes rocks to deform elastically, plastically, or fracture depending on the magnitude and duration of the applied force.

What is a fault in geological terms?

• A fault is a type of rock formation that is always stable.

• A fault is a volcanic eruption that occurs underground.

• A fault is a fracture or zone of fractures in the Earth's crust where blocks of rock have moved relative to each other.

• A fault is a layer of soil that prevents water drainage.

How do stratified rocks form?

• Stratified rocks form from volcanic activity.

• Stratified rocks are created by the cooling of magma.

• Stratified rocks form from the accumulation and compaction of sediment in layers.

• Stratified rocks develop from the solidification of ice.

What is the significance of the rock cycle in deformation?

• Deformation is unrelated to the rock cycle.

• The rock cycle is significant in deformation as it explains how rocks change under stress and temperature, leading to structural changes in the Earth's crust.

• The rock cycle is solely about the formation of new rocks.

• The rock cycle only affects sedimentary rocks.

Identify the three main types of faults.

• Tension faults

• Compression faults

• Normal faults, Reverse faults, Strike-slip faults

• Oblique faults

How does temperature influence rock deformation?

• Rocks become more brittle at higher temperatures.

• Temperature only affects the color of rocks.

• Temperature has no effect on rock deformation.

• Temperature influences rock deformation by making rocks more ductile at higher temperatures and more brittle at lower temperatures.

What role do tectonic plates play in rock folding and faulting?

• Tectonic plates prevent rock folding and faulting by stabilizing the crust.

• Tectonic plates are responsible for the weathering of rocks, not their folding or faulting.

• Tectonic plates only affect oceanic rocks, not continental rocks.

• Tectonic plates cause rock folding and faulting through their movements and interactions at boundaries.
