Answer:
The correct answer is D. How gravity interacts with planets
Explanation:
Einstein's theory of relativity formulated in 1915 introduces the following concepts:
- Formula E = mc2 (relationship between energy, mass, speed of light)
- How nuclear energy is produced
-After seeing a solar eclipse, gravity is interpreted geometrically (which is an effect of distortion)
-Relative time
Answer: he gave him a map of somewhere
Explanation:
Answer: Out of the given options bonds connecting atoms in reactants break, and bonds connecting atoms in products form are the changes which takes place when a chemical change occurs.
Explanation:
A change that leads to the change in chemical composition of a substance is called a chemical change.
For example, 
Here, bond between the reactant atoms nitrogen and hydrogen is broken down.
On the other hand, bond connecting the products that is 
and 
is formed.
Thus,, we can conclude that out of the given options bonds connecting atoms in reactants break, and bonds connecting atoms in products form are the changes which takes place when a chemical change occurs.
(1)
The health of coral colonies
The levels of carbon dioxide in the atmosphere
This is because corals are very sensitive to changes in the ocean's properties pH being included. Warmer oceans dissolves more carbon dioxide from the atmosphere hence making the waters slightly acidic. This will affect coral resulting in bleaching. This negatively affects the marine ecosystems since corals are usually at the bottom of the energy pyramid in these ecosystems.

Chlorofluorocarbons are very harmful to the environment when released into the atmosphere. They damage the ozone layer and therefore allow more UV rays from sunlight to reach the earth’s surface. They also have a greenhouse effect causing the earth’s atmosphere to warm up. This ultimately leads to global warming and climate change.
(3)
It would allow storm systems to stall in an area
Jets streams are very significant in that they influence weather patterns across the world. They are responsible for the movement of pressure systems and global air cells and their accompanying weather patterns. Because they generally sit in between cold and warm air systems they are significant in moving these air masses around. When they are weak they cause an air system to linger including storms causing excessive flooding in an area.
(4)
Absorb and re-emit infrared radiation.
Produced by human activity
Greenhouse gases do not allow infrared radiation from the earth's surface to escape back to space. Infrared is the electromagnetic wave spectrum responsible for transferring heat energy. Therefore, when left to linger in the atmosphere, they cause the greenhouse effect. This is the reason for global warming.
(5)
Air temperature –, ice
Ocean temperature – ice, a chemical isotope of <em>foraminifera</em>
Carbon dioxide levels – a chemical isotope of <em>foraminifera</em>
Kind of plants – fossilized pollen grains
Rainfall- the rings
