Answer: Five clocks are being tested in a laboratory.

Earth Science Notes Friction between the wind & the ocean surface generates undulations of water  waves Stormy area at Sea is called a ‘generating region’ Wave Interference: waves interacting with each other and waves that align create much larger waves and produce killer waves because the clashing of the energy from both or multiple waves Wave Refraction: the bending of waves and over time with erosion, the waves try to straighten the coastline out (Coastal Straightening) Types of Coastline:  Erosional: typically rugged, high relief (vertical elevation difference – between altitude of places), tectonically active  Depositional (east coast): gentle relief, sediments from different areas are deposited & available ­ Barrier Spits: deposits build up in areas that jut out into the ocean (don’t last very long) ­ Bay Barrier: body of water trapped by sand deposits (lagoon) ­ Tombolo: sand bridge, enough sand accumulates between island and land Jetty: a breakwater constructed to protect or defend a harbor, stretch of coast, or riverbank (Cred to Google for definition) ­ Groins: smaller versions of Jetty Beach: sediment (depositional material) in motion and an average picture of how big a beach is about 16 feet over tide Barrier Islands: long, narrow, depositional features; generally made of sand Coral Reefs (biological processes): simple marine animals with small bodies – related to many invertebrates ­ Largest Coral Reef is over a 1000 miles in length and 90 miles in width near Australia ­ Coral reefs need warm waters which are located near the equator and shallow water, so they form near land (sunlight)
