The answer to the question is true
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 weathering of the mountain peak will be mostly through the influence of the wind, water, and ice, while the bedrock under a forest will be influenced by the plants.
Explanation:
The weathering is a process that occurs everywhere in the world, on the surface and close to the surface of the planet. This process is basically the breaking up of particles from larger masses of rocks. Which type of weathering will be dominant at a particular place depends n multiple factors, such as:
- topography
- vegetation
- climate
- presence/absence of water
A bear mountain peak will be exposed to strong winds. Also, the lack of vegetation will enable the water from the rainfall to have big influence, while in the colder months the formation of ice will contribute to significant weathering. On the other side, the bedrock under a forest will have minimal influence from wind, water, and ice, as the vegetation provides protection. The vegetation on the other hand, with its roots, as well as with the decomposition will manage to weather the rocks, both on the surface and inside the ground.
