Climate does not effect the rate in which weathering can occur. true or false

Answers

This statement is false. Climate does affect the rate which weathering will occur.  Weathering will occur when there is a physical or chemical process to the landscape. Freezing and thawing will turn minerals, like silicate, into clay. When the weather is hot it causes faster chemical weathering than it would in say colder locations. Rocks will also break down faster in a wet climate. So, climate can effect the rate of weathering.

Answers

Answer:

C. Bronchial

Explanation:

The different types of lung sounds, also known as breath sounds differ from each other with respect to their location, pitch, relative duration, and intensity.

The bronchial breath sounds are heard just above the clavicle on either side of sternum bone and are characterized by loud amplitude, harsh quality, and high pitch. The bronchial breath sounds are hollow tubular.

The bronchial breath sounds have a short period of silence between the inspiratory and expiratory sounds. The expiratory bronchial sounds last longer than the inspiratory bronchial sounds (I<E).
