Title: How are Earthquakes and tsunami's alike and different? Post by: lenaelle on Feb 4, 2013 I'm helping my 2nd grader with an essay on comparing and contrasting earthquakes and tsunamis. She needs 5 reasons they are alike and 5 reasons they are different..everything I find online is way too complex for her. Any sites, books suitable for a 2nd grader on this? Sites would be best. Even the kids library books were too detailed and I need more simple general info on comparing/ contrasting these. Thanks
Title: How are Earthquakes and tsunami's alike and different? Post by: Firedancer51 on Feb 4, 2013 Sounds like the teacher is asking a rather absurd question--- earthquakes cause tsunamis, so comparing/contrasting makes no sense. I make spit but don't compare me to spit! Really really strange for a 2nd grader to have to answer.

Tsu. are waves on water, quakes make waves on land Both cause lots of damage Damage is in a limited area Instruments can measure the size of both Both happen without warning Different Quakes cause Tsu. but not the reverse Quakes can happen on land or ocean, but Tsu. occur only on water. Tsu. can cause damage far away Tsu. are only longitudinal (surface) waves, quakes have shear and compression waves as well. Quakes have aftershocks hours or days later, Tsu. only happen once after a quake. Tough question for 2nd grader -- be interesting in what they come up with.

Both are carried with waves (the earthquake is with seismic waves and the tsunami will tidal waves). Both generated by seismic activity. Neither can be predicted (well) beforehand. Both have epicenters Both are incredibly destructive natural phenomenon Different: Earthquakes travel through land while tsunamis travel through water Sorry that's all I got before it gets a bit complicated, hope I helped. Title: How are Earthquakes and tsunami's alike and different? Post by: nursing12w3 on Feb 4, 2013 I taught Earth Science for 27 years, and I'd agree completely with Wildturkey's answer. This is a very strange question for a 2nd grade class, a bit like asking the kids to compare/contrast asteroids with mass extinctions.
