The answer is urban areas
Answer:
Option C. Is used to cool the drill bit and to flush rock cuttings up and out of the drill hole
Explanation:
Drill mud plays a vital role in the drilling process. Its addition into the well-bore does a lot in enhancing the drilling processes and activities.
Among other importance and function of the drill mud /fluid:
1. It is used to cool off the drill bit
2. It flushes rock cuttings out of the drill hole
3. High pressure control
4. Providing buoyancy
5. Lubrication

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:
A. At the Arctic Circle, the sun’s rays travel through a thicker layer of atmosphere, reducing the amount of solar energy reaching the ground.
C. At the Arctic Circle, solar energy reaching the ground is spread over a smaller area, reducing the intensity of solar energy reaching the ground.
D. At the Arctic Circle, the daytime position of the sun in the sky is lower (closer to the horizon), reducing the intensity of solar energy reaching the ground.
Explanation:
- The arctic circle is the northernmost part of the world and is defined by the latitude of 66° 33' N the temperature of the warmest months in July and is below 10 ° C and thus has cool and cold summers.
- <u>Thus rays of the sun have to enter or travel through the thick layers of the atmosphere being at a height altitude and less sunlight is received at the poles and hence the small area gets insolation</u>.
- <u>Thus the day time position of the sun in lower latitudes of 40 to 60 degrees than it's in after noon time is more intense.</u>
