Question 12

is a necessary resource because it helps sustain life on Earth including humans,
animals and plants.

Answer 12

Soil

Question 13

is one of the traditional sources of income in our country done by planting
crops or raising livestock.

Answer 13

FARMING

Question 14

Through ___________________ water stabilizes the soil moisture thus
making it healthier and more suitable for planting.

Answer 14

Irrigation/drainage

Question 15

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.

Answer 15

Construction of Structure

Question 16

happens
when hazardous chemicals from human and industrial sewage are carelessly
disposed of, altering soil’s natural health and quality.

Answer 16

Waste Disposals

Question 17

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.

Answer 17

Forest Protection

Question 18

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.

Answer 18

Buffer Strips

Question 19

an approach that allows crops to remain in place for a season. This
keeps the soil from being left bare and unprotected.

Answer 19

No-Till Farming

Question 20

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.

Answer 20

Fewer Concrete Surfaces

Question 21

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.

Answer 21

Plant Windbreak Areas

Question 22

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.

Answer 22

Terrace Planting

Question 23

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.

Answer 23

Plant Trees

Question 24

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.

Answer 24

Crop Rotation

Question 25

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.
