Oceans	Oceans, continued	Physical Features of the Ocean	Types of Rocks	Plates and Layers of the Earth
100 70% The ocean covers how much of the Earth?	100 temperature and the amount of light As the depth of the ocean increases, __________________ decreases.	100 trenches The deepest parts of the ocean are __________________.	100 Sedimentary, metamorphic, and igneous Three types if rock are __________________, __________________, and __________________.	100 4.6 billion years old Scientific evidence indicates the Earth is how old?
200 Continental shelf The shallow parts of the ocean floor at the edges of the continents makes up the __________________.	200 The Gulf Stream An ocean current which carries warm water from the equator to Europe is __________________.	200 Tides It is mostly the pull of the moon's gravity that causes __________________.	200 igneous When molten rock or magma cools below the Earth's surface or cools after erupting from a volcana as lava, this type of rock is formed.	200 The Rock Cycle The Earth's surface is constantly changing due to heat and pressure withing the Earth and weathering and erosion at the surface. These processes constantly change rock from one type to another in a cycle called __________________.
300 saltiness The salinity of the ocean varies. What does salinity mean?	300 What is continental shelf. The greatest variety of ocean life is in the shallowest part of the ocean, above the __________________.	300 Mid-ocean ridges Underwater mountains caused by plate movements are __________________.	300 sedimentary Over a period of time, layers of sediment are pressed together to for these types of rocks.	300 inner and outer core. The two layers of the Earth that are composed mostly of rocky material are __________________.
400 ocean currents Wind patterns and different water densities cause __________________.	400 Phytoplankton These tiny plant-like organism produce much of the Earth's oxygen and serve as the basis of the ocean ecosystem. What are they?	400 ---- ----	400 metamorphic rocks Rocks formed from other types of rocks by intense heat and pressure deep withing the Earth are called __________________.	400 faults Most earthquakes and volcanoes are located at the boundary of plates, called __________________.
500 water pressure As the depth of the ocean increases, what else increases?	500 on the ocean's surface Phytoplankton, like other plants, need sunlight for photosynthesis, and therefore live where?	500 ---- ----	500 fossils Sedimentary rocks often contain these remains of organisms, called __________________, which tell us a lot about lfie and Earth in the past.	500 plates; plate movements Heat energy causes movement of material within the Earth. Large, continent-sized blocks that move slowly about due to this heat energy are called __________________. Mountain ranges, including the Appalachian mountains, mid-ocean ridges and trenches are
