The first reason was that his theory of continental drift was just too weak for most geologists to accept. Even though he believed the supercontinent that broke up into different continents moved, he did not have a clear explanation to how the continents moved. The other reason is that some of his explanation clashed with ideas that were widely accepted in the science communities. He used similar fossils from different continents to back up his theory of continental drift. However, at that time, many scientists that had observed similarities in fossils in places like South America and Africa believed there were similar fossils in different continents because of a land bridge that were formed by two continents.
Many science communities believe that land bridges allowed migration of many different species and even people to one place to another by large bodies of water frozen by low temperature known as ice age.
Answer:
potential energy, kinetic energy
Explanation:
potential energy is the energy held by an object because of its position. kinetic energy is energy in motion. when the bow is being drawn back it has potential energy because of its position and that at any moment it can be converted into kinetic energy.
That's a very good question!! That would have to go along with the process of weathering and erosion. Basically how the heat, weather, and he pressure of the Earth forms land . Mount Everest was formed when India plate moved rapidly northwards towards Euro Asia plate.
Hope this helps!!
A = (v2-v1) / t --> t = (v2-v1)/A
t = (55 km/hr)/(2.5 km/hr•sec)
t = 22 sec
Answer:
Option 2, Arousal
Explanation:
Reticular activating system (RAS) or the ascending arousal system consists of nuclei and tracts and is involved in the regulation of wakefulness, sleep aspects and arousal.
RAS is located in the mesopons and interacts with the basal forebrainand thalamocortical systems. It activates the cerebral cortex and thereby maintain the consiusness. The neurons located at the pontomesencephalic junctionparticipates in this activity of arousal.
Hence, option 2 is correct
