Earth’s atmosphere had little to no oxygen. It was composed of carbon dioxide, water vapor, and nitrogen, with lesser amounts of carbon monoxide, hydrogen sulfide, and hydrogen cyanide. Because of these gases in the atmosphere, the sky was probably pinkish-orange. Meaning once earth obtained more oxygen the sky turned blue.
The pattern of disproportionate dumping of toxic waste and other forms of pollution in neighborhoods where the poor and people of color live is called Environmental Racism.
This involves the placement of low-income or minority communities in the proximity of environmentally hazardous or degraded environments, such as toxic waste, pollution and urban decay. The socially marginalized racial minority communities are subjected to disproportionate exposure of pollutants and/or the denial of access to sources of ecological benefits such as clean water, air, and natural resources.
Newton's three laws of motion may be stated as follows:
1. Every object in a state of uniform motion will remain in that state of motion unless an external force acts on it.
2. Force equals mass times acceleration
3. For every action there is an equal and opposite reaction.
the third law is being used in this situation
Answer:Nuclear fusion
Explanation:
Which event takes place first in the stages before the birth of a star? Gravity pulls gas and dust together. A protostar forms as mass increases. Nuclear fusion begins under high pressure.
A, an object in motion stays in motion unless acted upon by an outside force.
