Module 10 & 11 Flashcards
Water has physical and chemical characteristics. Some of the physical attributes
include
temperature, color, taste, odor, and turbidity.
_______________________
affects some of the important physical properties and characteristics of water:
thermal capacity, density, specific weight, viscosity, surface tension, specific
conductivity, salinity, and solubility of dissolved gases, etc.
The temperature of water
_________, on the other hand, is primarily a concern of water quality for aesthetic reasons.
_____________water gives the appearance of being unfit to drink, even though the water
may be perfectly safe for public use. It can indicate the presence of organic
substances, such as algae or humic compounds.
color, colored
used
as a quantitative assessment of the presence of potentially hazardous or toxic organic
materials in water.
color
are human perceptions of water quality.
Taste and odor
is a measure of the light-transmitting properties of water and
is comprised of suspended and colloidal material. It is important for health and
aesthetic reasons.
turbidity
are a reflection of the soils and rocks
with which the water has been in contact.
The chemical characteristics of natural water
defined as the quantity of water that can be used for human purposes without
significant harm to ecosystems or other users.
Water availability
_______________________ occurs when the amount of water withdrawn from lakes, rivers or
groundwater is so great that water supplies are no longer adequate to satisfy all
human or ecosystem requirements, resulting in increased competition between water
users and other demands. _________________ can be caused primarily by human
activities which promote sedimentation, pollution, climate change, deforestation,
landscape changes, and urban growth.
Water scarcity
contributes to
pollution of the air, land, and water resources.
Human waste disposal
- can be defined as the organic and inorganic materials on the surface of the earth
that provide the medium for plant growth.
-develops slowly over time and is
composed of many different materials through the process of weathering.
Soil
is a necessary resource because it helps sustain life on Earth including humans,
animals and plants.
Soil
is one of the traditional sources of income in our country done by planting
crops or raising livestock.
FARMING
Through ___________________ water stabilizes the soil moisture thus
making it healthier and more suitable for planting.
Irrigation/drainage
activities, such as grading and filling, reduce soil quality on sites. Land use conversion usually done to support urbanization
activities can cause rapid soil degradation and sedimentation. Soil nutrients are
washed away making it unsuitable for farming.
Construction of Structure
happens
when hazardous chemicals from human and industrial sewage are carelessly
disposed of, altering soil’s natural health and quality.
Waste Disposals
Trees as well as other plants and vegetation in the forest are important in the creation
of new soil as leaves and other vegetation rot and decompose. Hence, soil qualities
are ensured when forest are protected and conserved.
Forest Protection
corridors of permanent vegetation used to reduce water and
wind erosion. They provide protection where stream banks exist. They can be created
with grass, trees and shrubs.
Buffer Strips
an approach that allows crops to remain in place for a season. This
keeps the soil from being left bare and unprotected.
No-Till Farming
Soil requires an adequate amount of water in order to function properly. Lots of
_________________, especially in residential areas make it difficult for water to get to
the soil. Using paving stones for patios and gardens work to protect the soil. They
are also a tool to prevent soil erosion in specific areas.
Fewer Concrete Surfaces
are composed of shrubs, plants and trees. They work in combination
and serve a conservation purpose. These will work together to slow the force of wind
over ground areas. This is a method that can also work to prevent erosion of the soil.
Plant Windbreak Areas
This type of planting is done by maximizing the topography of the land. It benefits
from the way the rain water flows naturally. This is a way to protect the soil from
erosion. It is also a proven method to encourage growth from moist soil areas.
Terrace Planting
a good conservation method. As the tree grows, its roots
become even more secure in the soil. This soil is protected in numerous ways because
of the trees’ existence. Erosion is prevented from this planting process.
Plant Trees
a process that works to conserve soil. It is accomplished by planting
and growing a serious of different crops in the same soil. This process prevents
overgrowth of pathogens and a lack of fertility in the soil, overall.
Crop Rotation
This is a simple process that provides a lot of benefits to the soil. _______________ your soil
along with plants and vegetables is important. This helps to not only nourish the soil
but to protect it. Moist soil is not in danger of erosion due to wind activity.
Water the Soil
is an indication of the acidity or alkalinity of soil and is
measured in pH units.
Soil pH or soil reaction
are native crop options that enhance the soil. Planting these is a
way to ensure conservation efforts. They should be planted even when diverse crops
are being planted, as well.
Indigenous Crops
is another of tree
planting method wherein the areas under trees are protected. This is usually done
by planting foliage in forest undergrowth areas. It encourages healthy soil and water
absorption.
Afforestation
plays a critical role in conserving soil. Monitoring the areas where
cows and other animals graze is important. This helps to prevent depletion of the
soil. It also addresses the issue of hoof damage, which can occur to the soil.
Monitor Grazing
important resources when it comes to soil conservation. These structures
work to prevent soil erosion. This is especially important in areas where rivers exist.
Flooding of rivers has been the cause for many instances of soil erosion.
Dams
The use of organic _________ improves the quality
of soil because it is composed of readily biodegradable materials make better nutrient
sources.
fertilizer
A simple conservation method that some gardeners and farmers apply is not to
_______________. This is a protection method that is helpful. You can do this by
creating dedicated paths in your garden. This helps you to not walk on wet soil
causing it to be compacted.
No Soil Compacting
Setting up large container to hold excess water in problem locations is helpful. This water can be re-
used for watering gardens and yards.
Control Storm Water
