The nine activities that scientists engage in as a part of scientific inquiry are the following:
1. Observe
2. Define the problem
3. Form a study question
4. Research the problem
5. State the expectations (hypothesis)
6. Experiment and gather data
7. Analyze the results
8. Reflect on the findings
9. Communicate with the wider community
4.6 billion years ago
The study pushes back the clock on the origin of Earth's water by hundreds of millions of years, to around 4.6 billion years ago, when all the worlds of the inner solar system were still forming. Scientists had suspected that our planet formed dry, with high-energy impacts creating a molten surface on the infant Earth.
i hope this helped, have a nice day! (o:
I think the correct answer from the choices listed above is option A. For metamorphism to occur, the parent rock must be in solid form. Metamorphism is the alteration of the structure of a rock by factors like heat and temperature so it must be the material should be in solid form.
The Bear population would increase due the the raise in the salmon population.
Explanation:
Sun plays an important role in our solar system especially planet like earth are dependent on sun for food, water and air. Sun helps to balance the ecosystem on earth.
Here is an assumption what would happen if sun disappear for one day only, it would be more curt if it disappear forever but from POV of one day below are certain consequences of such a situation over solar system,
- You might be thinking if sun disappear then we would be seeing the moon for a whole day but don't forget, moon don't have it's own light, it reflects the rays coming from sun if sun disappear then surely moon would be like a ball kept in dark.
- It would happen for the first time if an asian man calls to someone in Europe, usually when here is night there is day and vica versa, but this time both will have same appear (night only)
- There's a idiom in Indian Hindi language that says "seeing the stars during the day time" which we use when we are going through something worse that we see the stars during daytime, but this time every human being on earth will see the stars during daytime, do not forget stars have their own light, they are not sun dependent.
- For the first time Night Blooming Jasmine will bloom and spread it's fragrance for 24 hours.
- Often when the earth revolves around its axis, a certain part of it receives light from the sun.But for the first time the earth will rotate around its axis without the sunlight falling on any part.
- people who are not allowed to go out of the house at night time can now enjoy the night out in the day too.
- Those trees and plants who slept in the hope that they would cook food in the morning with sunlight, they would not even know that their food has gone missing.
- Our ozon layer will have it's first leave from his duty.
- The bad thing is for the patients of night blindness, they will not be able to see this imaginary scene.
