During a visit to the beach, you get in a small rubber raft and paddle out beyond the surf zone. You become tired, so you stop and take a rest. Describe the movement of your raft beyond the surf zone. The raft will move toward shore along with the water particles underneath the raft. The raft moves up and down vigorously due to the breaking of waves that are taller than waves in the surf zone. The raft moves in a circle, and it returns to essentially the same place. The raft's net movement is not toward the shore compared to the surf zone.

Which of the following statements provides a possible logical explanation for the increased number of tornadoes during the 1990s and 2000s compared to the 1950s and 1960s? select all that apply Population increases mean that more people could report tornadoes in more areas. Larger warm fronts in mid-latitude cyclones produce more tornadoes. Using Doppler radar more effectively allows scientists to detect more tornadoes than was previously possible. Tornado warnings when tornadoes don't occur can cause the number of tornadoes to look greater than it actually is.

Of the following statements about density stratification, which is/are true? Choose all that apply. The origin of Earth's oceans and atmosphere are a result of density stratification. Density stratification has caused Earth's internal structure to be layered. Outgassing is a direct result of density stratification. Density stratification caused the oxygen crisis on Earth. The time periods of the geological time scale are based on events caused by density stratification. Density stratification has caused the highest-density material to be found at Earth's core.

Of the following statements about tsunami, which is/are true? Choose all that apply. View Available Hint(s) At the coast, a tsunami looks like a suddenly occurring high or low tide, which is why they are misnamed "tidal waves." Tsunami have a very long wavelength, so they travel at very high speeds (equivalent to the speed of a jet airplane). If you are at a beach and the water suddenly drains out away from shore, it is safe to go explore the newly exposed land. A tsunami suddenly appears as a huge breaking wave as it arrives at the shoreline. The tsunami warning system uses seismic waves and deep-ocean pressure sensors to detect tsunami. Tsunami are undetectable by ships in the open ocean.

Imagine an earthquake is about to occur at location 2 on the map (southern Alaska). Which of the following statements is most accurate? All locations (except 9) could benefit from an alert that an earthquake occurred at location 2, because they are near the ocean and might experience a resultant tsunami. Only location 2 could benefit from an alert so people can evacuate before the earthquake occurs. Location 2 is not in the middle of the ocean and therefore will not produce a tsunami, so none of the locations need to be notified of the earthquake. There are no locations on the map that could benefit from an alert that an earthquake at location 2 occurred, because they won't feel any of the effects. Most of the people living at location 2 probably are aware that they live in a location where earthquakes are likely.
