Question

how does water protect crops frm frost and hot air currents

Answer 1

Water is absorbed by the plant roots. Along with water, minerals and fertilisers are also absorbed. Plants contain nearly 90% water.Thus it has a good heat absorbing capacity. Also, water protects them from the cold air temperatures. The water freezes onto the crop, a process that releases heat and provides the necessary warmth to protect the crop from the harsh freezing temperatures that could cause damage.
