How do you think the speed a satellite fall towards Earth compares to the speed it is moving forward? What would happen to a satellite if its orbit speed was reduced by half? How about if it doubled?

It falls toward earth if speed decreases.

Explanation:

If the speed of satellite was reduced by half, it fall towards the earth because it is attracted by the earth with the help of gravitational force while on the other hand, if the speed of satellite increased by double, it will go into the space because the gravitational force of earth does not keep it in the orbit due to its higher speed so we can say that speed of satellite has a great effect on satellite motion.

the answer is a) a shiprock was formed by igneous process

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
