Catastrophism is associated with major changes that occurs once at a time in a species while gradualism is associated with tiny changes that occurs over a period of time that finally contributes a bigger evolutionary change.
<u>Explanation:</u>
The events that are sudden, short-lived, violent occurring worldwide thereby changing the shape of the Earth is Catastrophic. This process is opposite to contrast to gradualism which is also called as uniformitarianism. This process is associated with slow and also incremental changes. Erosion is the best example for this process.
The formation of major mountain chains and great floods are some of the examples of Catastrophism. Both are associated with the changes that occurs in a species by the time taken for the changes determines whether it is Catastrophism or gradualism.
Answer:
An object in motion stays in motion unless an external force acts on it.
Explanation:
Newton's first law, the law of inertia, states that an object will remain at rest or in motion unless acted upon by another force.
Answer:
The theory of common descent states that all living organisms are descendants of a single ancestor. Hence, common descent helps scientists better understand why species living in different geographical regions exhibit different traits. Some of these traits are highly conserved among broad animal classifications (e.g., vertebrates or tetrapods), and seemingly different species (e.g., birds and reptiles) share inherited physical and genetic traits, and successfully adapted organisms typically produce more offspring.
Explanation:
In evolutionary biology, it is theorized that a group of organisms share common descent if they have a common ancestor.
Answer: Oxisols
Explanation:
The soils that is present on the old land surface unless the parent material were strongly weathered before they were deposited.
These are soils are rich in iron and aluminium oxides. This soil is not good for cultivating crops and agriculture because it does not tightly binds to the crops and plants.
It leaches very easily so considered poor for cultivation. They are mostly found in the tropical rain forest.
