Why do planets that are the same size have different surface area?
If you are referring to two planets of the same MASS, then the difference in surface area would probably be due to their relative densities. If one planet is composed of denser matter than the other, then the same mass would take up a smaller volume, and thus the surface area would be smaller.
What is the core temperature of planet Mars?
The core of Mars is cooler than the Earth. Why depends on the surface area relative to the volume of a planet. A larger planet like Earth has a lot of volume and a limited amount of surface area by which to radiate its internal heat to space. Mars is smaller but has more surface area per volume than Earth, so it can radiate its internal heat away to space more efficiently than Earth. There are other smaller differences in the initial heat of accretion and the heat released when the core forms from an initially homogeneous mass, but the surface area is the biggest factor. like none of this has an actual temperature
Why do the big stars shine brighter than the smaller stars?
The big stars have more hydrogen to burn and has much more surface area thats why it shines brighter.
If red giants are cool stars why are they so bright?
Red giant stars emit less light per square meter of surface area than smaller, hotter stars, but their larger size means they have a larger surface area from which to emit light, so they emit more light overall.

True or false the sun's rays are concentrated over a smaller surface area in winter?
no
Does a smaller rock a have higher or lower percentage of surface area than a larger rock?
It depends on percentage related to WHAT! You cannot express surface area as a percentage of volume since the dimensions are different. So the only percentage you can have is the suface area of the smaller rock as a percentage of the surface area of the larger rock. In that case, the answer, not surprisingly, is that the smaller rock has the smaller percentage surface area.It depends on percentage related to WHAT!

Which has the greater surface area one large cell or 27 smaller cells?
If the smaller cells' total volume is at least that of the larger cell then the smaller cells have the greater surface area.
Will a smaller surface speed up a chemical reaction?
No. A smaller surface area will slow down a chemical reaction.
Is the surface area of an object be smaller than the volume?
It can be.
Which has a smaller surface area - cone or sphere?
cone
What is the relationship between surface area and weathering rate?
The rate of weathering also depends on the surface area that is exposed. Mechanical weathering breaks rocks into smaller pieces. As the pieces get smaller, their surface area increases. When this happens, there is more total surface area available for chemical weathering. The result is that weathering has more of an effort on smaller particles.
Why do high heels have a smaller surface area?
This is not necessarily true. Only when the heal tapers will its surface area be smaller. The surface area is that which is in contact with the ground. Platform shoes are likely to have the same surface area as normal shoes, and stilettos will have a very tapered heel and therefore small surface area and great pressure per square unit)
Do cells divide to have a smaller surface area?
No. In fact, if they retain their combined volume, their surface area would increase.
Why does the Arctic fox have smaller surface area to volume ratio compared with a British fox?
The smaller the surface area, the less body heat the animal will lose. So small surface area to volume ratios are great in cold environments.
What happens to surface area when rocks are broken into smaller pieces?
As a substance is broken, the surface area greatly increases. For example a 2 meter cube has a total surface area of 24 square meters. If a 1 meter cube is cut out of one corner, the total surface area is now 30 square meters.
How big is Ukraine compared to Texas?
Ukraine has a surface area of 603,550km2 which is about 70,000km2 smaller than Texas. Ukraine's surface area is about 89% that of Texas' surface area.
