the days at the poles are always shorter than at the equator
B. it is warmer near the equator than near the poles
C. the nights at the poles are always shorter than at the equator
D. it is warmer near the poles than near the
equator

4. 4. Eighth grade students in a Louisiana middle school planted a
vegetable and flower garden at the school. They discovered that
some plants grew well and others did not. All the plants received soil—it was good soil for some plants, but it did not contain some things needed by other plants. Study the chart above and then answer the questions which follow. Look at the description of the soil horizons. Root crops, such as beets, require a sandy soil with low acidity to grow well. Blueberries require an acidic, sandy soil. Grasses grow well in most types of soil with high acidity. Which of these plants would probably grow well in soil near the students’ school? Which plants would grow most poorly in this soil? Give reasons for your answers?
Soil Around the School A
Dark, grayish brown; low amount of humus (decayed plants and animals); many roots; strongly acidic; sandy B
Yellowish red; few roots; strongly acidic; sandy near top, sandy clay near bottom C
Partly weathered rock; few deep tree roots

5. Erosion
Wind
Water
Ways to limit
Cause
Cause
Ways to limit
Keep ground covered with plants or
parts of plants all year
Increase the roughness of the surface
of the soil
Plow in curved, not straight rows
Keep soil in clumps, not broken up
in small pieces
Long and steep
slopes
Uncovered soil that
rain can quickly
wash away
Soil that will not
absorb water well
Keep ground covered with
plants or parts of plants all year
Shorten the length and lessen
the steepness of the slope
Mix sand with soil to absorb
more water
Loose surface soil
Wind strong enough
to lift pieces of soil
Long, unbroken
expanses of soil
5. The area where the class planted their garden is on a slope. From the information in the concept map, what might you be able to do to limit erosion in the garden?
