Gravity causes stars to form out of gas clouds
.
<u>Explanation:</u>
The formation occurs in molecular clouds in the interstellar space. The atoms of light are first forced under sufficient pressure so that their nuclei undergo fusion. The gravitational force is responsible for this fusion to begin.
The gases present in these clouds clump to form molecules with higher densities. Due to the internal gravitational disturbance, there begins to occur a collapse of the denser regions of the cloud. As the collapse continues to occur, the temperatures begin to increase and each of the smaller clouds will eventually form a star.
The Coloumbian exchange was the exchange of species between the Old and the New continents. Because of this we can for example choose between cofee and cacao to drink: Cofee is from the Old, and Cacao from the new World. Similarly, if you've even eaten food that included tomatoes (New world) and rice (Old World) - this is only possible with Columbian exchange.
Carl Rogers was a humanistic psychologist who lived throughout the 20th century. He supported the idea that in order for a person to develop, they need an environment that provides them:
- Genuineness: To behave with openness towards others.
- Acceptance: Being to see ourselves in a continuous positive way.
- Empathy: The chance of being listened to and understood.
He developed the concept of "self-actualization", which occurs when a person's ideal self is highly represented in his o her current behavior (real self).
