Science Vocabulary Part 2

the rock that forms Earth's outer layer (a)  

• crust
• mantle
• core
• atmosphere

the rock below the crust; made of hot rock (a)  

• mantle
• Core
• Sediment
• Crust

Match the following

• layer of molten metal

• outer core

• lies beneath the ocean

• oceanic crust

• dense ball of solid metal

• continental crust

• forms the continents

• inner core

heat from the core and from the mantle carry hot solid rock of the mantle outward, the rock cools then sinks back down in a never-ending cycle

• Radiation

• Conduction

• Subduction

• convection currents

Reorder the following

• weathering and erosion

• transportation

• deposition

• compaction

• cementation

Match the following

• eroded material can be moved by wind and water

• deposition

• over time, layers of sediment are squeezed together

• compaction

• dissolved materials glue compacting sediment together

• weathering and erosion

• rocks are broken down and carried away

• cementation

• sediment settles out of water or wind into layers

• transportation

forms form cooled magma or lava

• sedimentary rock

• igneous rock

• metamorphic rock

• concrete

forms when small particles are pressed and cemented together (a)  

• sedimentary rock
• Metamorphic rock
• Igneous rock
• Volcanic ash

forms when a rock is changed by heat and pressure or by chemical reactions (a)  

• Igneous rock
• metamorphic rock
• Sedimentary rock
• Fossilized rock

the series of processes that occur on Earth's surface and in the crust and mantle that slowly change rocks from one kind to another

• Carbon cycle

• Water cycle

• rock cycle

• Plate tectonics
