during which moon phase do spring tides occur?

new moon and full moon
first quarter and third quarter
waxing gibbous and waning gibbous
waxing crescent and waning crescent

new moon and full moon

Explanation:

Tides occur due to gravitational force of the sun and the moon. During New moon and Full moon, the Sun and the Moon are aligned in a straight line. This alignment leads to strong effect of gravity on tides and highest high tides and lowest low tides occur. These tides are referred as spring tides.

Neap tides occur when the sun and the moon are aligned at right angles. Effect of gravity is minimum and low tidal range is observed.

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion
