Question 1

What is urban heat island effect?

Accepted Answer

Higher temperatures in urban areas due to impervious surfaces and waste heat

Answer

Urban areas are warmer than surrounding rural areas because paved and built surfaces absorb more heat and lack evaporative cooling.

Question 2

Which conservation tillage practice involves planting directly into previous crop residue without plowing?

Accepted Answer

No-till farming
