Answer:
1- Option (D)
2- FALSE
Explanation:
The seafloor spreading takes place because of the divergent plate motion. Alfred Wegener observed this motion of the seafloor and the continents but was not able to explain the main mechanism behind this until the new theory came into the picture. The divergent motion of seafloor and the motion of the continents were explained by the universally accepted theory known as the Plate tectonic theory. This theory was able to explain the mechanism behind this plate motion.
The study of the seafloor spreading provided some pieces of evidence that supported the continental drift theory. They gave a basic idea about how the oceanic plate gets subducted (consumed) at the convergent plate motion that undergoes partial melting at greater depth. As a result of which the magma rises up to the surface on the overriding plates.
The crust represents the outermost layer of the earth. They are of 2 types, namely the oceanic and the continental crust. These crusts when slide past one another in a transform plate boundary, it is neither created nor destroyed. It remains conserved.
Thus, the correct answers are given above and the second statement is false.

The population of humans on earth has reached its carrying capacity or the maximum number of individuals an environment can support over time without destroying or degrading it, is determined by several key factors. Food availability, water, and space
The impact of so many people on the environment Two major forms follow
- the consumption of resources such as land, food, water, air, fossil fuels, and minerals.
- Consumption-related waste such as air pollutants, water pollutants, toxins, and greenhouse gases.
Population growth is the growth of the population on earth. For most of human history, our population is relatively stable. However, innovation and industrialization have made energy, food, water and medical supplies more accessible and reliable.
