Based on the red-shift data on galaxies, most astronomers infer that the universe is currently

Expanding

The photograph below shows an impact crater approximately 1 mile wide located in Diablo Canyon, Arizona. Describe the event that produced this crater. 


Barringer Crater was caused by the impact of a meteorite (or meteor or comet or asteroid).

Compared to the JOVIAN planets, terrestrial planets are 

( two things) 


more dense and less massive.

A red giant star would most likely have a temperature of

The temperature T in degrees Celsius (°C) is equal to the temperature T in Kelvin (K) minus 273.15:

T(°C) = T(K) - 273.15

5,000ºC

PUT ON YOUR THINKING HATS 

The Moon has many more impact craters visible on its surface than Earth has on its surface. State two reasons that Earth has so few visible impact craters.


Friction from Earth's atmosphere causes many meteors to burn up; Many meteors fall into the ocean so craters aren't visible; Old craters are eroded away; Vegetative growth may hide evidence of a crater; Plate tectonics has destroyed some craters; Deposition has buried some craters

The diagram below represents two photographs of the moon, A and B, taken at full moon phase several months apart. The photographs were taken using the same magnification. Each photograph was cut in half and the halves placed next to each other.
