Ecological Site Analysis

The branch of biology dealing with the relationships of organisms to one another and their physical surroundings, or the political movement to protect the environment, especially from pollution.

Igneous rocks are formed from the cooling and crystallization of magma (molten rock) or lava.

Sedimentary rocks form when sediments (like particles from weathered igneous rocks) are deposited, compacted, and cemented together.

are rocks changed by heat, pressure, or chemical reaction. When sedimentary rocks are pushed to deeper levels of the earth; they transform into metamorphosed rocks.

Deals with the origin, nature and distribution of landforms.

The relationship between soil composition and appropriate land usage.

The material that makes up soil. Includes mineral particles, organic matter, water, and air.

Capacity of soil to withstand pressure from a weighted object like a building foundation.

Occurs when gravity water is not readily transmitted by the soil, causing frequent or permanent saturation.

The rate at which water penetrates the soil surface.

The rate at which water moves within the soil through a given volume of material.

The rate at which water in a soil pit or pipe within the soil is taken up by the soil.

Texture describes the composite sizes of particles in a soil sample.

Understanding slope forms for site design requires understanding of local geologic, soil, hydrologic, and vegetative conditions.

Describes the shape of the earth's surface by contour lines.

Imaginary lines that join point of equal elevation on the surface of the land above or below a reference surface

identifying features on a map by using symbols and signs or names

Understanding slope forms for site design requires understanding of local geologic, soil, hydrologic, and vegetative conditions.

Describes the shape of the earth's surface by contour lines.

is commonly crushed for use as an aggregate in construction projects

Is used in buildings, bridges, paving, monuments, and many other exterior projects. Indoor, polished granite slabs and tiles are used in countertops, tile floors, stair treads and many other design elements.

was used to make knives, arrowheads, spear points, scrapers.

is used as aggregate in lightweight concrete, as landscaping aggregate, and as an abrasive in a variety of industrial and consumer products

has been used as a building material since ancient times because it is easy to work with and relatively soft. Used or famous statues

these materials were initially limited to road construction. Now the application have spread over the area of roof construction, for industrial purposes, carpet tiles, paints and as a special coating for waterproofing

decorative aggregates, as building stone, as facing stone, garden decoration, office bldgs., curbing, arrowhead, construction aggregate, cutting tool, spear point

for Interior: decorative aggregates, home, interior decoration; for Exterior: As bldg stone, as facing stone, garden decoration, office buildings, paving stone

it is popular for a wide variety of uses such as roofing, flooring, and flagging because of its durability and attractive appearance

It is used for its optical properties In cosmetics, paint, and paper. It used because it is an abundant, low-cost commodity in crushed stone prepared for construction projects

use as a construction aggregate, building stone, or decorative stone

Refers to the description of landforms

Irregularities on the earth's surface. They are derived from volcanic, glacial, or erosional processes

help guide in site selection for residential, industrial, and other forms of development that involve surface and subsurface structures

◦ Mineral particles ◦ Organic matter ◦ Water ◦ Air

• It comprise 50% to 80% of the volume of the soil and form the all important skeletal structure of the soil. • Sand and gravel particles provide for the greatest stability, usually yield a relatively high bearing

is the term used to describe the composite sizes of particles in a soil sample.

There are 12 basic terms for texture at the center of which is Class

refers to the soil's ability to transfer gravity water downward through

Expressed graphically in terms of slope profile, a silhouette of a slope drawn to known proportions with distance on the horizontal axis and elevation on the vertical axis

the inclination or slant of the land

is an elongated depression sloping towards a drainage basin such as a sea, lake or swamp, and which may contain water or may be dry.

is a prominent projection of raised land from higher ground, such as a hill or mountainside into lower land
