Exam 6: Terrestrial Worlds in the Inner Solar System

Which terrestrial planet shows the least evidence of recent volcanic activity?

According to studies of impact cratering,which of the terrestrial planets has the oldest surface?

Which of the following are sites of volcanic activity on Earth?

How much would you have to change the temperature of an object if you wanted to increase its flux by a factor of 100?

The Mars rovers named Spirit and Opportunity found evidence in the chemical makeup of the rocks that proves Mars had liquid water on its surface in the past.

How does the radioactive heating of Earth vary from when it was first formed 4.6 billion years ago until today?

Give a specific example of impacts of asteroids/comets that have happened on Earth.Why are impact craters rare on the surface of Earth,but plentiful on the Moon?

At what wavelength does your body radiate the most given that your temperature is approximately that of the Earth,which is 300 K?

Permanent magnetism in the Earth's solid iron core is the source of Earth's magnetic field.

Star A emits a continuous spectrum of light that peaks at a wavelength of 450 nm.Star B emits a continuous spectrum of light that peaks at a wavelength of 700 nm.What is the ratio of the temperature of star A to star B if the emissions from both stars follow Wien's law?

The smoother,less cratered surfaces of the Moon resulted from those areas being protected by the Moon's proximity to Earth.
