The answer is c. on the earth’s surface directly above the initial release of seismic energy.
The definition of an epicentre: the point on the earth's surface directly above the origin of an earthquake (Cambridge Dictionary)
In Geology, we said that it is directly above the focus, which is the initial release of seismic energy mentioned in the above sentence.
As the other options do not have the correct location (e.g. within the Earth's surface, beneath the focus).
Therefore, the answer is c. on the earth’s surface directly above the initial release of seismic energy.
Hope it helps!
Answer: The distant and the Earth
Explanation:
Because the Mar is too far away that its gravity is unable to reach you and also the gravity of Earth is too strong
Answer:
A, B and D
Explanation:
The continental crust contains igneous, sedimentary and metamorphic rocks. Along convergent plate boundaries, the continental crust gets renewed with igneous rock providing more rock to be made into sedimentary rock. The sedimentary rock can then continue to sink into the crust becoming metamorphic. Due to this variety of types of rock, the minerals can be diverse, including sodium, potassium, aluminium and calcium. Continental crust is also much thicker, up to 70km.
Answer:
10 meters
Explanation:
A wave is a natural phenomenon that travels through a material medium but does not have a permanent effect on the particles of the medium. It can either be electromagnetic or mechanical. The propagation of a wave can be represented by a sinusoidal graph, which has crests and troughs.
A crest is the point of maximum displacement, while trough is a point of minimum displacement. The distance between two crests or troughs gives the wavelength of the wave.
From the question, the horizontal distance between a crest to the next trough is 5 meters which is half of the wavelength.
Thus wavelength = 5 × 2
= 10
The wavelength is 10 meters.
