An explosion occurs when the timescale for the energy release by some process is much shorter than the timescale on which a system can adjust to damp the energy release process. In the present day Sun, nuclear fusion is a very slow process: on average it takes many billion years for a proton to fuse with another. This timescale is quite temperature dependent, so you might have thought the centre of the Sun might heat up quickly, leading to a runaway "explosion". However, an increase in temperature leads to an increase in pressure that would expand the Sun, reducing the core density and temperature and decreasing the rate of nuclear fusion again. The timescale for the Sun to react in this way is just millions of years, so this acts like a thermostat that keeps the reactions under control.
Answer:
Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock.
Explanation:
Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock.
Answer:
Erosion can cause water in the rivers to become heavily polluted. The water might carry pesticides, heavy metal ions and other toxic wastes. When this water will be used for irrigation purposes, the growth of plants will be heavily affected by them.
When humans use water this contaminated water from the rivers, it will led to many diseases in humans. Also, the wild- life animals which depend on this river might take in toxic compounds due to which they might die.
Answer:
Question 1: getting there
Mars- between 150 and 300 days depending on where mars is in relation to the earth, the speed of the launch, and the exact travel path that will be taken
Uranus- about 9 and a half years
Question 2: weather
Mars- the atmosphere is completely thin, and an extremely cold planet, with an average temperature of around -80°
Uranus- has very strange seasons due to its tilt, has a surface temperature of about -300°F, strong winds, and sometimes clouds made up of methane ice crystals
Question 3: clothing
Mars and Uranus- both mars and Uranus are unsuitable for humans, you would most definetly need a full body space suit such as the Z-2 Spacesuit created by NASA
you can answer the rest based off imagination and Google for facts
I believe the answer is D.
I'm pretty sure
