Answer:
The growth of forests.
Explanation:
The Carboniferous Period occurred around 300 million years ago
It is named because many coal beds were formed during this era.
During, the Carboniferous period the first extensive forests appeared on Earth. The expansive growth of these forests removed huge amounts of carbon dioxide from the atmosphere.
For thermometers to read temperatures correctly, they must be immersed in the substance being measured while reading the temperature. When they are taken out the substance, there is a possibility that the fluid inside would change its level due to the sudden change in the temperature. Thus, giving you an erroneous reading of the temperature.
The average velocity can be calculated from the slope of the graph
Explanation:
In a position-time graph, the position is represented on the y-axis while the time is represented on the x-axis.
The slope of the graph is given by:
where
is the change in the y-variable
is the change in the x-variable
However, we have:
- corresponds to the change in position, therefore it is the displacement
- corresponds to the change in time
This means that the slope can be rewritten as
However, this ratio corresponds to the definition of average velocity:
Therefore, the slope of a position-time graph gives the average velocity.

<span>a tsunami travels at a speed that is related to the water depth - hence, as the water depth decreases, the tsunami slows. The tsunami's energy flux, which is dependent on both its wave speed and wave height, remains nearly constant. Consequently, as the tsunami's speed diminishes as it travels into shallower water, its height grows.</span>
