Mechanical Weathering/Geologic Map

these are used to show various physical features of the earth, such as mountain ranges, deep ocean trenches, and volcanoes

• Topographical map

• Abrasion

• Geologic Map

• Universal Map

roots forcing their way into tiny cracks and exerting tremendous pressure on the rocks as they grow, which widens the cracks and breaks the rock

• root force

• mechanical force

• frost-wedging

• tree-root wedging

the physical process that breaks rocks apart without changing their chemical composition

• chemical weathering

• natural weathering

• mechanical weathering

• abrasion

rock that is formed through the cooling and solidification of magma or lava

• metamorphic rock

• igneous rock

• weathered rock

• sedimentary rock

one of the large pieces of earth's surface that moves separately; earth's surface is made up of these

• continental plate

• crusted plate

• geological plate

• dinner plate

the splitting or breaking apart of rock by the pressure of water freezing in cracks and crevices
