C
Explanation:
Ice-covered surfaces are highly reflective of the sun's rays therefore prevent those areas from warming as much as the areas where the ice is replaced with darker, less reflective surfaces which absorb heat and thus contribute more to global warming. Albedo is the percentage of radiation reflected by the earth's surface. Clear surfaces have greater albedo values than dark surfaces.
To locate <u>positions</u> in east and west directions, <u>cartographers</u> use lines of <u>longitude</u>, also known as <u>meridians</u>. Longitude is the distance in degrees <u>east</u> or <u>west</u> of the prime meridian, which is the reference point for longitude.
<h3>What is a topographic map?</h3>
A topographic map can be defined as a type of map which contains an accurate and detailed graphical (two-dimensional) description, representation or records of both natural and man-made (artificial) features on the surface of planet Earth.
Generally, a topographic map make use of contour lines to represent points of equal elevation above sea level such as:
- Mountains
- Hills
- Plains
- Valley
<h3>What is a line of longitude?</h3>
A line of longitude can be defined as an imaginary great circle of constant longitude on the surface of planet Earth which passes through the North pole (terrestrial pole) and South poles (Meridian) at right angles to the equator.

Answer:
Modern theory of evolution explains that "organisms change over time as a result of changes in heritable physical or behavioral traits". Hence this change suggests the loss of vestigial organs.
Explanation:
- Vestigial organ are those which do not have any function but is present in our body.
- According to the modern theory the genetic and physical appearance changes along with the adaptation in environment by the organism.
- So if the organ looses its function in order to sustain and adopt in the changing environment then they become vestigial and slowly disappear.
- This is the common example for the Lamarck's theory of "use and disuse".

Your question is incomplete.
Explanation:
Although this is a correct statement, since in the species of land turtles the temperature is a determinant of sex.
If the egg is exposed to temperatures below 40-38 degrees Celsius, the sex will tend to be male or male, and if a temperature of 40 degrees Celsius occurs constantly throughout the incubation, it will be female.
The suns role in the water cycle is to heat the water enough so that it evaporates. This allows the water to rise up into the sky where it is then cooled and condensed into clouds, once the clouds are too dense it rains and the cycle begins again with the sun heating the water. The sun allows the cycle to continue infinitely
