HONORS EARTH SCIENCE VOLCANO STATION LAB NAME _____________ PARTNER __________ DATE ______ HOUR ___ You may need your rock chart and volcano notes STATION 1- 3 ROCKS Match the rock with the type of volcano letter Name of rock Volcano type Cinder Shield Composite STATION 2- PACIFIC OCEAN FLOOR MAP Besides Hawaii, name another island chain formed from a hot spot _____________ Find a trench on this map. What is its name _________________ Use plate names to describe how this trench formed: What type of volcano would be found near the trench? _________________ STATION 3- ATLATIC OCEAN FLOOR MAP What type of plate boundary is happening in the middle of the Atlantic Ocean ________ Which two plates are meeting here? __________________ & ___________________ What type of igneous rock would you find along the Mid-Ocean Ridge? _____________ What type of volcanic eruption would happen here? _______ STATION 4- MT. RAINER TOPO MAP What type of volcano is Mt. Rainier? _______________ How do you know? Name any igneous rock you may find at Mt. Rainier. ___________ What is the contour interval of this map? _________ STATION 5- KILAEUA, HAWAII What is the contour interval of this map? ____________ How does this contour interval compare to Mt. Rainier (station 4) ? __________ Why is there a difference? Name an igneous rock you may find here ____________________ Explain why. A chain of islands formed from a hot spot and formed the pattern below, what direction is the plate moving? _____ label the oldest island. Explain how you determined it was the oldest.
