Seismic waves are sent through the earth during earthquakes, and those
energy waves are what cause the ground to shake as they travel through
it.Seismic waves travel at different speeds when they pass through
different types of material, so by studying seismograms, scientists can
learn a lot about Earth's internal structure.Body waves are seismic
waves that travel through Earth's interior, or its 'body.' Surface waves
are seismic waves that travel through Earth's surface.Surface waves are
important, but they don't provide much information about what happens
below the surface. For this, we need to study body waves so that we can
see what Earth's 'body' is like.
There are two types of body waves, called P waves and S waves. P
stands for primary waves because these waves travel the fastest and are
detected first. S stands for secondary waves because these are slower
than P waves, arriving second on the seismogram.
The word that most adequately completes the fragment is Small because the rocks of the Grand Canyon do not span a wide span of geologic time.
<h3>What is geological time?</h3>
Geological time is a term to refer to the frame of reference used to represent the events of the history of the Earth and of life in chronological order. It establishes divisions and subdivisions of the rocks according to their relative age.
<h3>What is the Grand Canyon?</h3>
The Grand Canyon is a colorful and rugged gorge carved out by the Colorado River over millions of years in northern Arizona, United States.
The Canyon was created by the Colorado River, whose course undermined the land for millions of years. It is about 446 km long, has mountain ranges between 6 and 29 km wide and reaches depths of more than 1,600 m.
Additionally, nearly 2 billion years of Earth's history has been exposed as the Colorado River and its tributaries cut through layer after layer of sediment at the same time the Colorado Plateau was uplifted.
According to the above, it can be inferred that the Grand Canyon exposes a small portion of the earth's history because it exposes only about 1.7 to 2 billion years and the Earth is about 4.5 billion years old.
