Weathering (2)
Erosion
100
The study of our planet, Earth; how it is made; what it is made of; and how it has changed over time.
What is geology
100
layers of sediments (fragments of rocks, minerals, or animal or plant materials) form this rock
What is Sedimentary Rocks
100
physically breaks up the rocks
What is physical weathering
100
rocks change into other materials
What is chemical weathering
100
wind causes smaller sediments to move in the direction of the blowing wind
What is wind erosion
200
Scientist who studies the Earth; how it is made; what it is made of, and how it has changed over time.
What is Geologist
200
When melted lava from a volcano is cooled and harden form this rock
What is Igneous Rock
200
water get's into rock's cracks, freezes, expands, and breaks off pieces of rock.
What is Frost Wedging
200
when oxygen changes the color of the rock into a rust/orange color
What is oxidation
200
rainfall, waves, rovers, and floods, carrying the sediments downstream
What is water erosion
300
Process where rock is dissolved, worn away, or broken into smaller pieces
What is Weathering
300
Sedimentary or Igneous rocks change from heat and pressure for this rock.
What is Metamorphic Rocks
300
blown air and rushing water hits rocks and begin to crumble over time.
What is abrasion
300
water causes the rock to dissolve (disappear)
What is dissolution
300
giant slabs of ice that move slowly over land carving landforms bringing sediments with them as they move
What is glacier erosion
400
Rocks and Sediments are moved from one place to another
What is Erosion
400
How are mountains formed
What is the tectonic plates compress together to form landforms.
400
rocks peel off into sheets
What is exfoliation
400
Causes the rock to change color as well dissolve
What is Acid Rain
400
pulls rocks down the side of a mountain and cliff
What is gravity erosion
500
Process by which rocks, sand, and sediments are left in a new place by the forces of weathering and erosion
What is Deposition
500
what is the most abundant rock in NH?
What is granite
500
plant roots break up rocks as they grow larger
What is plant action
500
Name all the types of weathering that caused the Old Man to fall
What is Physical Weathering-Frost Wedging, Wind Abrasion, Water Abrasion, Exfoliation, and Plant Action Chemical Weathering Chemical Weathering-Acid Rain
500
Name all the types of erosion that made the Old Man fall down
What is Glacier, Wind, Water, Gravity, and Deposition. Glacier Erosion-naturally carved out the face thousands of years ago. Wind Erosion-high up in the mountains it is windy and took small sediments and moved them off the old man Water Erosion-rain fell often in the mountains and made the small sediments fall down the mountain Gravity erosion-when the piece of the nose and other sediments fell it went to the bottom of the mountain Deposition-all the pieces landed at the bottom of the mountain
