Answer:
The climate in that area is different today than when tropical plants and animals lived there
Explanation:
The most likely reason for the absence of those tropical animals in North Texas would be the climate.
Climatic conditions have varied through geologic history of our blue planets. When these conditions changes, organisms have to adapt and on the long run, the environment won't be able to sustain them. They become phased out.
It is possible for rock records in a place to bear different fossil records records that are not similar compared to the life we have in such areas today.
The Sahara desert for example has huge fossils of fishes in its rocks. Today, the area is a hot desert and contains very low biodiversity. Sciencist have proposed that the region was previously a lush green tropical forest and the ocean covered some parts too. Today, the Sahara's climate has changed.
It is possible, during times of drought, for water that has been removed from the root zone of the plant as a result of downward percolation to travel back up into the root zone through capillary movement.
This will be discussed in further detail below.
<h3>What exactly is the movement of capillaries?</h3>
Percolation is the process by which water moves downward through the root zone of a plant. When circumstances are dry, water that has traveled downward through the root zone as a consequence of percolation may possibly travel back up into the root zone of the plant. In general. capillary movement and migration
Only when the adhesive forces in the liquid are greater than the cohesive forces, which always produce surface tension, can capillary action take place. Capillary action is a physical phenomenon.
In conclusion, the phenomenon known as capillary action refers to the movement of a liquid through a limited space either without the assistance of any external forces, such as gravity, or even in opposition to such force.

Answer is B. Air temperature rises and air molecules move faster.
The Sun warms equatorial regions of Earth Low than the poles. This causes an area of toward pressure to develop near the equator. As a result, the northeast and southeast trade winds are created as air at the surface then flows less the equator.
<h3>Why does
air tend to rise in equatorial regions?</h3>
The reason of the air tends to rise in equatorial regions because in the equatorial regions there is more sunlight as compared to other areas. There is difference in the heat in different areas due to that warmer air rises.
Thus, option B is correct.
