Faults and Stress

What type of fault is this?

• Normal

• Reverse

• Strike-slip

Answer explanation

The question asks about the type of fault. The correct answer is 'Strike-slip'. A strike-slip fault is a type of fault where the movement is predominantly horizontal. This differentiates it from the 'Normal' and 'Reverse' faults, which involve vertical movements.

What type of fault is this?

• normal fault

• reverse fault

• strike-slip fault

Answer explanation

The question asks about the type of a fault and the answer is 'normal fault'. A normal fault is a type of fault where the hanging wall slides downward due to tension in the crust. Thus, the correct answer to the question is 'normal fault' and not 'reverse fault' or 'strike-slip fault'.

Forces that changes rock shape or volume is called

• tension

• compression

• stress

Answer explanation

The forces that change the shape or volume of a rock are referred to as 'stress'. This term encompasses all forces, including tension and compression, that result in physical changes to a rock. Among the options given, 'stress' is the correct term that broadens to include all such forces.

Reverse faults have __________________ and folding that formed the Alps and Himalayas.

• tension

• compression

• stress

Answer explanation

The question asks about the feature of reverse faults that contributed to the formation of the Alps and Himalayas. The correct answer is 'compression'. This is because reverse faults are caused by compression forces, which push rocks together. This action leads to uplift and folding, contributing to the creation of mountain ranges like the Alps and Himalayas.

________________ pulls on crust which results in a normal fault.

• tension

• compressions

• stress

Answer explanation

The correct answer is tension. In geology, a normal fault occurs when the crust of the Earth is pulled apart due to tension. Compressions and stress are different processes that don't directly cause a normal fault by pulling on the crust.

Normal faults occur at a divergent boundary.

• true

• false

Answer explanation

The question asks if normal faults occur at a divergent boundary. The answer is true. This is because normal faults are indeed formed due to tensional forces, which cause the crust to pull apart. This pulling apart is precisely what happens at divergent boundary, where tectonic plates move away from each other, leading to the creation of space where new crust can form. Thus, normal faults occur at a divergent boundary.

Strike slip faults move by ____________________.

• pulling apart

• pushing together

• slipping past each other

Answer explanation

The question asks about the movement of strike-slip faults. These are a type of fault in which rocks on either side move past each other. So, the correct option is 'slipping past each other', as it accurately describes the movement associated with strike-slip faults. This movement is not about pulling apart or pushing together, hence those options are incorrect.

Which type of force is involved with this type of fault?

• Compression

• Tension

• Shear

Answer explanation

The type of force involved in this type of fault is compression. A compression force is associated with a reverse fault. It is a stress that decreases the volume of a material, which is what happens in a compression type of fault.

Which type of fault is this (stress pushing in on both sides)?

• Normal

• Reverse

• Strike-Slip

Answer explanation

The question asks about the type of fault where stress is pushing in from both sides. This describes a reverse fault, as it occurs when the crust's compressive forces cause one section of rock to be pushed up relative to an adjacent section. Therefore, the correct answer is 'Reverse'.
