Unit 5 - Landforms and Alternative Energy

Fuels formed over millions of years from the remains of ancient plants and animals

• fossil fuels
• alternative energy
• thermal energy
• electricity

a type of rock that forms when layers of sediment are pressed together 

• sedimentary rock
• igneous rock
• metamorphic rock

the breaking down of rocks into smaller pieces by wind, water, and ice

• erosion
• weathering
• deposition
• sediments

the movement of sediment by wind, water, and ice

• weathering
• erosion
• deposition
• sediments

the dropping off (depositing) of eroded materials by wind, water, and ice

• weathering
• erosion
• depostion
• sediments

natural resources that are used up faster than they can be replaced

• renewable resources
• non-renewable resources
• alternative resources
• biofuel

a resource that can be replaced in a reasonable amount of time

• non-renewable resource
• renewable resource
• alternative resource
• coal

pressure on buried solid material causes the material to stick together and turn to rock

• cementation
• compaction
• melting
• freezing

when sediments dissolve in water and stick together to form rock when the water evaporates

• compaction
• cementation
• melting
• freezing

energy resources that we use instead of fossil fuels

• fossil fuels
• alternative energy 
• non-renewable energy
• coal
