Answer:
Mechanical weathering breaks rocks into smaller pieces without changing their composition. Ice wedging and abrasion are two important processes of mechanical weathering. Chemical weathering breaks down rocks by forming new minerals that are stable at the Earth's surface.
Answer:
x = 4.9285 ft
Explanation:
q = 2.3 ft²/person
y = 7 ft
n = 15 persons
We can apply the formula
A = x*y
or
A = q*n = (2.3 ft²/person)*(15 persons)
⇒ A = 34.5 ft²
then we have
A = x*y ⇒ 34.5 ft² = x* 7 ft
⇒ x = 34.5 ft² / 7 ft
⇒ x = 4.9285 ft (wide)
Answer:
Subduction of Pacific plate under North American plate
Explanation:
There has been constant collision between the two plates, namely the Pacific plate and the Central American plate. As a result of which the <u>Pacific plate has got subducted</u> and <u>rate of subduction is very intense and fast</u> here because this lies in the region, commonly known as the "ring of fire".
Due to this subduction, the plates at great depth undergoes dehydration and partial melting occurs, that allows the magma to rise up to the surface forming volcanoes on the central America. There exist a huge number of volcanoes that includes cinder cone, composite as well as shield volcanoes.
B.
The larger distance from the source caused the delay between the earthquake reaching Sarah and then reaching Tonya.
