The 1919 Red Scare - the craziest year in America Which of the following processes are a result of tides (tidal gravity) between a planet and its moon? U the gradual slowing down of rotation rates of planets and moons synchronous rotation (a moon always keeping the same face toward its planet) ring systems around planets the gradual change in orbital separation between a planet and moon QUESTION 2 Due to its lack of a large moon, Mars also lacks a strong magnetic field plate tectonics a stable climate large volcanoes QUESTION 3 Suppose you live on Mercury, and you base your calendar on Mercury's years and solar days (just like we do on Earth, using our own planet's years and solar days). Tonight you're celebrating your 20th birthday. Tomorrow night, what birthday will you be celebrating? still your 20th your 21st your 22nd QUESTION 4 Why does the Earth have a higher density than Mercury, even though Earth is only 40% heavy metals and Mercury is 70% heavy metals? Mercury's core contains different metals than Earth's Earth's core is compressed by its thick mantle Mercury's mantle contains different rocks than Earth's Mercury is hotter
