<h3><u>
The following events are identified as chemical weathering:</u></h3>
- The minerals in a marble statue react with water to form acids and pores in the structure.
- The rocks in a region are streaked orange after being exposed to repeated rains.
<em><u>Reason: </u></em>
When the weathering process occurs due to <em>chemical reaction</em>, then it is considered as chemical weathering.
In <em>the first case</em>, minerals of marble statue are <em>reacting</em> with water to cause weathering. In the <em>second case</em>, due to the <em>acidificaion reaction</em>, the change of the color has happened after exposure to the repeated rains.
<h3><u>
The following events are identified as Mechanical weathering:</u></h3>
- A piece of rock crumbles after being constantly thrashed by strong waves.
- Industrial runoff forms cracks in a rocky structure in its path.
<em><u>Reason:</u></em>
When the rock is broken into simple pieces <em>without any chemical reaction </em>it is considered as mechanical weathering.
In the <em>first cause</em>, due to the <em>abrasion</em> caused by the strong waves, weathering has happened, in the <em>second case</em> industrial run off may be of varying temperature and thus may cause <em>heating or cooling</em> of the rock and causes weathering.
this is true. when it is warmer the plant and insects can migrate to these other places so they do not have to die or hibernate through winter
The ciliated simple columnar epithelium is a tissue that would line the uterine tubes and function as a conveyor belt to help move a fertilized egg toward the uterus. The ciliated columnar epithelium transfers mucus and constituents through cilia and is originate in the upper respiratory area the fallopian tubes, the uterus, and principal part of the spinal cord. It is the main objective of contamination for common cold illnesses.
The food chain that would include an aphid include:
- Plant ---> Aphid ----> Birds
- Plant ---> Aphid ----> Spiders
- Plant ---> Aphid ----> Bat
<h3>What is a food chain?</h3>
A food chain is a chart that shows how food is transferred from producers to consumers.
Producers are plants as they are responsible for producing food from inorganic materials using the Sun's energy.
Consumers depend on plants and other organisms.
The food chain that would include an aphid include:
- Plant ---> Aphid ----> Birds
- Plant ---> Aphid ----> Spiders
- Plant ---> Aphid ----> Bat
