Answer: Scientific questions are those questions that can be answered through observation of world around us and by experimentation.

Explanation:

The scientific questions related to the earth and the space science are as follows:

1. How the celestial bodies like moon, sun, and others affect the functioning of the earth?

2. How earth is different from other planets in the space?

3. What is the distance covered by the earth from other celestial bodies including other planets in the solar system?

4. How asteroids and meteors affect the earth?

5. Why different regions of the earth receive different intensities of light from the sun?

Answers

Explanation:

Ans1:-)Gravity is the force that connects every object - planet, the Sun, moons, asteriods, comets - to every other object. The Earth is constantly being tugged by all the other bodies in the solar system. Except for the Sun and the Moon, most bodies are either too small or too

Ans2:-)Earth is one special planet. It has liquid water, plate tectonics, and an atmosphere that shelters it from the worst of the sun's rays. But many scientists agree our planet's most special feature might just be us. ... The fact that Earth hosts not just life, but intelligent life, makes it doubly unique

Ans3:-)For objects within the solar system, distances are calculated from their orbital parameters and are center to center distances. For objects outside of the solar system, those objects are so far away that there is no discernable difference between the center to center distance and the surface to surface distance.

Ans4:-)Such collisions could have caused the larger bodies to be broken up into the smaller objects we observe as meteorites. Much evidence suggests that the asteroids could be the parent bodies of meteorites.

Ans5:-)Because of the Earth's tilt the sun's rays strike the surface at a slant at the poles; they are less focused. ... The tilt of the Earth causes different areas to receive different amounts of solar energy. The difference in solar energy received at different latitudes drives atmospheric circulation.

Likewise, his wife, Martha Washington, could also be considered the "Mother of America," as demonstrated by her roles as the general's wife and the first lady.During the American Revolution, Martha Washington earned the title of "Mother of America" for her caring nature as the general's wife. She was also very brave. Despite the danger of kidnapping, Martha refused to abandon her home, Mount Vernon, in Virginia. When Martha did leave the plantation for periods of time, she traveled to the military camps where Washington was staying. First, Martha had to be vaccinated so that she would not suffer from smallpox. Once she was inoculated, Martha made the risky trip to camp. British and American soldiers roamed the countryside, and capture was a real possibility. Nevertheless, Martha arrived at each winter camp. She acted as confidant and secretary to George Washington, who believed that her presence was crucial. She encouraged the soldiers, helped their wives, and comforted those who were wounded. One of her key roles was also to entertain important visitors to the camp. Occasionally, Martha Washington even represented George at events he could not attend. Martha used her position to contribute to fundraising efforts for military supplies in 1780 and knit socks for the soldiers herself. Overall, her care and attention to others' needs made her the "Mother of America" during the American Revolution.What evidence does the author use to support the idea that Martha Washington should be considered the "Mother of America"?A. British and American soldiers roamed the countryside, and capture was a real possibility. it is not B.C. First, Martha had to be vaccinated so that she would not suffer from smallpox.D.
