A geological fold occurs when one or a stack of originally flat and planar surfaces, such as sedimentary strata, are bent or curved as a result of permanent deformation.

So A fold is a Bend? in a rock. Maybe.

A fault is a planar fracture or discontinuity in a volume of rock, across which there has been significant displacement as a result of rock-mass movement.

Answer:

A bold is a bent in a rock.

A fault is a crack in a rock

Explanation:

A bold is a bent in a rock.

In earth's structure, when a flat plate of sedimentary rocks are pressed due to the plates movement into one another, the plate structure takes the shape of a bent structure or curved structure. The rocks buckle into folds. Fold are commonly seen in rock structure that is layered.

A fault is a crack in a rock.

Faults in a rock structure is formed due to stress. Faults are associated with the boundaries of the earth's tectonic plate. Fault is a zone of fracture between two blocks of mountain rocks and it causes relative motion in two sets of rock blocks.

What is the intensity of 60dB sound?

polet [3.4K]

Answer:

The intensity of the sound in W/m² is 1 x 10⁻⁶ W/m².

Explanation:

Given;

intensity of the sound level, dB = 60 dB

The intensity of the sound in W/m² is calculated as;

$dB = 10 Log[\frac{I}{I_o} ]\\\\$

where;

I₀ is threshold of hearing = 1 x 10⁻¹² W/m²

I is intensity of the sound in W/m²

Substitute the given values and for I;

$dB = 10 Log[\frac{I}{I_o} ]\\\\60 = 10 Log[\frac{I}{I_o} ]\\\\6 = Log[\frac{I}{I_o} ]\\\\10^6 = \frac{I}{I_o} \\\\I = 10^6 \ \times \ I_o\\\\I = 10^6 \ \times \ 1^{-12} \ W/m^2 \\\\I = 1\ \times \ 10^{-6} \ W/m^2$
