GEOS2201
Fairmont State Exosphere Exam 2
| Question | Answer |
|---|---|
| Craters | evidence of impact (stuff slammed into the moon and made a dent) |
| Mare | called seas; lava flows that are dark colored and show tectonic activity |
| Rilles | valleys/rifts, evidence of earlier tectonic motion |
| If your mass is 60 kg on earth, how much is your mass on the moon? | 60 kg |
| Why does the moon not have a climate? | with low gravity, there is no atmosphere for the water cycle. also, there is no insulation to filter sunlight out or keep it in |
| How long does it take the moon to rotate? | 27.3 days |
| How long does it take the moon to revolve? | 27.3 days |
| What explains why we see various amounts of the moon's surface? | the moon is lit by different amounts of sunlight |
| Order of objects in a lunar eclipse | sun earth moon |
| Order of objects in a solar eclipse | sun moon earth |
| What causes tides on earth? | the gravitational pull of the moon and sun |
| What is the rule of the moon's gravity on earth's tides? | it pulls on the ocean closest to it but also causes a bulge on the other side |
| How often do high and low tides occur in one day? | twice (they're diurnal) |
| What is the order of the objects in a spring tide? | the sun earth and moon are lined up |
| What does the daughter hypothesis state? | the earth was spinning and a piece from the ocean flew off |
| What does the capture hypothesis state? | the moon was a wandering planet captured by earth's gravity |
| What does the sister hypothesis state? | the earth and moon were formed at the same time from the same material |
| What does the giant impact hypothesis state? | a giant asteroid type structure struck earth and the moon formed from debris of that collision |
| What does Newton's first law state? | an object at rest/in motion remains at rest/in motion until an outside force acts upon it |
| What is the natural state of things? | in motion |
| What does Newton's second law state? | there is a relationship between force, mass and acceleration |
| What type of relationship do force and mass have? | direct: as one increases, the other increases |
| What type of relationship do force and acceleration have? | direct: as one increases, the other increases |
| What type of relationship do mass and acceleration have? | indirect: as one increases, the other decreases |
| What does Newton's third law state? | for every action, there is an equal and opposite reaction |
| What are the three natural forces? | electromagnetic, nuclear, gravitational |
| Electromagnetic force | motions of electrons create magnetic/electrical field |
| Gravitational force | gravity pulls on one another |
| Nuclear force | strong force holding the nucleus of an atom together |
| If two objects of the same size/shape are released from the same height at the same time, what will happen? | they will hit the ground at the same time |
