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 escape velocity

DanielleElmas [232]

Escape velocity is the speed that an object needs to be traveling to break free of a planet or moon's gravity well and leave it without further propulsion. For example, a spacecraft leaving the surface of Earth needs to be going 7 miles per second, or nearly 25,000 miles per hour to leave without falling back to the surface or falling into orbit.

1. A student is biking to school. She travels 0.7 km north, then realizes something has fallen out of her bag.

Snezhnost [94]

Explanation:

(a) Displacement of an object is the shortest path covered by it.

In this problem, a student is biking to school. She travels 0.7 km north, then realizes something has fallen out of her bag. She travels 0.3 km south to retrieve her item. She then travels 0.4 mi north to arrive at school.

0.4 miles = 0.64 km

displacement = 0.7-0.3+0.64 = 1.04 km

(b) Average velocity = total displacement/total time

t = 15 min = 0.25 hour

$v=\dfrac{1.04\ km}{0.25\ h}\\\\v=4.16\ km/h$

Hence, this is the required solution.
