Question

which of the following is a consequence of drought?
a. reduced agricultural production
b. higher water levels in lakes
c. increased fish populations
d. greater tree growth
what is the purpose of rainwater harvesting?
a. to filter ocean water for irrigation
b. to collect and store rain for later use
c. to reduce soil erosion
d. to increase stormwater runoff

Explanation:

First Question (Consequence of Drought)

Drought is a period of low rainfall. For option a, less water means crops get insufficient moisture, so agricultural production reduces. Option b is wrong as drought causes lower, not higher, lake water levels. Option c is wrong because less water harms aquatic life, reducing fish populations. Option d is wrong as drought limits water for trees, hindering growth.

Rainwater harvesting focuses on collecting rain. Option a is wrong as it's not about ocean water. Option b matches the definition: collect and store rain for later (e.g., irrigation, household use). Option c: soil erosion reduction is not the main purpose (though it can be a side effect). Option d is wrong as rainwater harvesting reduces stormwater runoff, not increase it.

Answer:

a. Reduced agricultural production
