True
Explanation:
70% of the population of China lives on only one fourth of the land.
Answer:
Shield volcanoes are built by many layers over time and the layers are usually of very similar composition. The low viscosity also means that shield eruptions are non-explosive. There are two types of lava flows, pahoehoe which is a ropy type of lava that flows easily (low viscosity).
Answer:
The greatest gravitational potential energy is at apogee. The greatest kinetic energy is at perigee. Total Energy is constant.
Explanation:
The gravitational potential energy is at its greatest when the satellite is farthest from the earth, this point is called the apogee. And at this point the kinetic energy will be at its minimum.
The kinetic energy is greatest when the satellite is closest to the earth, this point is the perigee. And at this point the gravitational potential energy will be at a minimum level.
the total energy is the sum of the gravitational potential energy and the kinetic energy.As the satellite orbits the earth, the kinetic energy and the gravitational potential energymay be interchanged but the total energy will remain unchanged.
C since in 2011, the South Sudanese voted on a referendum in which about 99% of the voters voted to separate from Sudan and to become an independent country.
