Answer:
Answer is C. Observe planetary position with sufficient accuracy so that Kepler could later use the data.
Explanation:
Tycho Brahe was an astronomer and astrologer which support the geocentric theory, that is , theory about the earth, and the solar system. He built astronomical instruments used in his work or findings.
In his findings , he observed the planetary position, that is ,the distance between the sun and the earth, as the earth goes or moves around its orbit.
This findings was later used by Kepler in discovering the laws of planetary position.
Answer:
Population growth is a problem.
Explanation:
Population is a problem because we have to worry about if we have enough resources to support them and there has been a scientific study done that proves more carbon dioxide is put into the air which doesn't help with air pollution.
Answer:
In troposphere air temperature decreases with increase in altitude.
Explanation:
When the sun rays hit the surface of earth it absorbs the energy of sunlight and after some time the heated surface of earth emits heat which increases the temperature in the lower regions of the troposphere while the top layer of the troposphere is cooler than the regions below hence the variation.
