It is responsible for shaping the Earth's surface and forming the geologic features that are seen on the surface of Earth.
(a)
What are the two types of Weathering?
(a)
It occurs when the oxygen dissolved in water will oxidize some materials.
Oxygen
Carbonation
Oxidation
Biological Action
The physical breakdown/chemical alteration of rocks at or near the Earth's surface are referred to as (a) .
It is a large, moving mass of ice where they are found in many parts of the world, especially in the poles or in high mountains.
Valley Erosion
Flood Plain
Glacial Till
Glacier
It is formed when a stream reaches a flat area called piedmont or gently sloping plain.
Delta
Flood Plain
Alluvial Fan
Leeves
It is the slow movement of regolith down a slope, as observed in bent trees and fences.

A rock broken into chunks after being carried by rapidly flowing water.
Pulverized rock resulting from a landslide.
Splits in a rock due to tree roots.
Form as a result of flood deposits on the banks of channel

Sand dunes
(a) is the transport of weathered sediments by agents of erosion and transported to different places.
What are the agents of erosion?
Water
Wind
Ice
Fire
When rock is broken down and disintegrated without any chemical alterations, the process in operation is
physical weathering.
chemical weathering.
hydrolysis.
erosion.
The fact that water expands as much as 9% of its volume as it freezes is the basis of
oxidization.
exfoliation.
salt crystal growth.
frost wedging.
________ occurs as rock surfaces heated by the Sun during the day expand slightly, and then contract with nighttime cooling.
Exfoliation
Thermal expansion
Frost wedging
Salt-crystal growth
When rock is broken down and disintegrated in the presence of water and with chemical alterations to the rock, the process in operation is
physical weathering.
chemical weathering.
mass movement.
biological weathering.
When rainwater attacks formations of limestone, the minerals dissolve and wash away with the mildly acid rainwater. This is an example of
oxidation.
crystallization.
frost action.
carbonation.

What is the slow, steady, downhill flow of loose, weathered Earth materials, especially soils?
Slump
Landslide
Mudflow
Creep
What are swiftly moving mixtures of mud and water?
Slump
