Hot and dry conditions for an exteded period of time.
Dehydration stress caused by drought leads to cell membrane damage, protein denaturation, and oxidative stress in plant cells. In addition, drought can disrupt essential cellular processes such as photosynthesis and nutrient uptake. Finally, prolonged drought conditions can trigger programmed cell death in plants as a survival mechanism.
Drought is a subtle, insidious natural hazard that is a normal part of the climate of virtually all regions of the world. Its occurrence results in a myriad of economic, social, and environmental impacts in developed as well as developing nations, although the characteristics of its impacts differ considerably between the two settings. Drought is considered by many to be the most complex but least understood of all natural hazards, affecting more people than any other. It is a normal feature of climate and its recurrence is inevitable. However, there remains much confusion about its characteristics. It is precisely this confusion that explains, to some extent, the lack of emphasis on proactive drought management efforts in most parts of the world. Through an improved understanding of the inevitability and characteristics of drought, as well as its differences from other natural hazards, scientists, policymakers, and the public will be better equipped to establish much-needed policies and plans whereby future vulnerability to drought can be reduced.
The drought we're in , but don't know what to call the drought. :)
A long period of no rain is called a drought.
it will probably be very hot and dry and there will be plants just they will be small hope that helps!:)
During a drought, tree rings tend to be narrower as the tree growth slows down due to lack of water. The rings may also appear darker or more compact than usual, indicating the challenging conditions the tree faced. Combining these characteristics can help scientists identify past drought events by studying tree ring patterns.
A period with little rain is a drought.(The archaic equivalent was drouth.)
The word is drought.
how big is a drought or how tall
A drought will dry everything up.
where does drought happen the most and why?
