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.

Answer:
If two plates move away from each other then a continental rift will form.
Explanation:
There are three basic types of plate boundaries, convergent, divergent, and transform plate boundaries. All of them have their own characteristics and the boundaries can be between oceanic and oceanic, oceanic and continental, and continental and continental plates, and each type creates different landforms.
If there are two plates moving each other over land, then a continental rift will form. Basically, the two plates slowly move away from each other, opening a gap that is constantly widening, so over time, it grows into a rift valley. Over the course of millions of years, the continental rift or rift valley will get filled by oceanic water and physically separate the two landmasses. A perfect example of this is the divergent plate boundary between the Nubian and Somali plates which have created the rift valley cutting through the eastern part of Africa.
