parent material of soil

sediments hardened

category of soil when it reaches and deposited in sea water

soil passing a No.200(75-μm)sieve that is nonplastic or very slightly plastic and that exhibits little or no strength when airdry.

passes a No. 4 (4.75-mm) sieve and is retained on a No. 10 (2.00-mm) sieve.

when a river is formed by the glaciers melting

Gain of heat

it can have cementation or silt particle

is the subdiscipline of civil engineering that involves natural materials found close to the surface of the earth.

Soil categories:

rainwater trap in a basin between two mountains

a clay with sufficient organic content to influence the soil properties.

particles of rock that will pass a No. 4 (4.75-mm) sieve and be retained on a No. 200 (75-μm) sieve with the following subdivisions:

a soil comprised primarily of vegetable tissuein various stages of decomposition,usually with an organic odor, a dark brown to black color, aspongy consistency, and a texture ranging from fibrous to amorphous.

is defined as the uncemented aggregate of mineral grains and decayed organic matter (solid particles) with liquid and gas in the empty spaces between the solid particles.

category of lake Deposits

combined effect of heat, pressure and plastic flow

passes a No. 40 (425-μm) sieve and is retained on a No. 200 (75-μm) sieve.

loss of heat

ASTM stands for

Transported to another location

particles of rock that will pass a 3-in. (75-mm) sieve and be retained on a No. 4 (4.75-mm) sieve with the following subdivisions:

passes a 3⁄4-in. (19-mm) sieve and is retained on a No. 4 (4.75-mm) sieve.

soil passing a No.200(75-μm) sieve that can be made to exhibit plasticity (putty-like propeties) within arange of water content sand that exhibits considerable strength when airdry.

particles of rock that will pass a 12-in. (300-mm) square opening and be retained on a 3-in. (75-mm) sieve,

exhibit plasticity

category of glacial Till

AASHTO stands for

category of gravity Transported

new minerals will be formed

transported by glaciers

by rolling it down a slope

prominent to shore

small particles

passes a No. 10 (2.00-mm) sieve and is retained on a No. 40 (425- μm) sieve.

category of river Deposits

a very fine soil, 75 micrometers in diameter

glaciofuvial Soil also called:

passes a 3-in. (75-mm) sieve and is retained on a 3⁄4-in. (19-mm) sieve.

a silt with sufficient organic content to influence the soil properties.

is the branch of science that deals with the study of the physical properties of soil and the behavior of soil masses subjected to various types of forces.

involves chemical process

especially during flood or sorted according to size

formed by metamorphism

degradation of rocks

no change in the composition of rocks

It includes the application of the principles of soil mechanics and rock mechanics to the design of foundations, retaining structures, and earth structures.

breaking down of rocks

particles of rock that will not pass a 12-in. (300-mm) square opening

is the application of the principles of soil mechanics to practical problems.

remains on the same/original location

involves mechanical process

example of Wind-Transported

category of Wind-Transported

cooling of magma

may be defined as the unconsolidated sediments and deposits of solid particles that have resulted from the disintegration of rock

soil deposits

can be defined as a natural aggregate of minerals that are connected by strong bonding or attractive forces; for this reason, _______ is often considered a consolidated material.

non plastic
