Another word for chemical weathering is
Neporo4naja [7]

Answer:

1. Another word for chemical weathering is b. disintegration

Chemical weathering is a process by which the rocks are broken down into parts and sediments by the action of a chemical agent such as alkali or acid. The disintegration can be a natural process by which a solid body is broken down into parts or subparts.

2. d. moving water is not an agent of chemical weathering agent.

The chemical weathering can be caused by the agents like lichens which secretes acid on the rock surface and causes it's disintegration, acid rain and salt water are chemical agents that can cause the disintegration of the rock but moving water will have little influence on the hard rock surface.

3. c. chemical weathering is a process which turns rocks and minerals into new substances. The chemical weathering process brings change in the chemical composition of the rocks due to the action of the weathering agents  hence, on disintegration of rocks new substances are formed.

Why does the reporter have a tube up his nose? why does the reporter have a tube up his nose? to replace the salts and other ion
Helga [31]
The correct answer is to accurately measure core temperature.
The tube seen entering the reporter's nose is a thermistor which is used to measure the core temperature of the body with very high levels of accuracy. The tube reaches the esophagus, which is one of the most preferred locations for measuring the core temperature.
The core body temperature is the operating temperature of the human body and it refers to the temperature of the deeper structures of the body instead of the peripheral tissues. 
The esophagus is close to the left ventricle of the heart, it has a deep body location and a quick response to any changes in the body temperature.

Water is able to travel against gravity, from the roots of a plant to the leaves at the top of the plant.
Juliette [100K]

Answer:

<em>The correct option is B) Capillary action, when adhesive forces are stronger than cohesive forces.</em>

Explanation:

When water leaves from the leaves of a plant through events such as transcription, a gap is produced in the capillary action of the xylem tube. As a result, more water is drawn from the roots to fill the void. The forces of attraction between the water and the xylem tube are much greater than the intramolecular forces of water. As a result, the water flows in an upward direction due to these string adhesive forces present between the water and xylem tube.
