DDT is an insecticide that was formerly used to control insects that would eat crops. It was banned from use in the 1970s.
Reil [10]
<h2>It contains toxins</h2><h2>It killed off bird populations.</h2><h2>It caused harm to human populations.</h2>

Explanation:

Let us understand the term DDT

DDT : Dichlorodiphenyltrichloroethane

  • This is a crystalline chemical compound
  • Basically used for protecting insects eating crops
  • It is colorless, odorless, tasteless
  • Initially used as pesticides

It killed off bird populations: Though it does not kill birds directly by consuming, it has indirectly damaged the egg by making the egg's shell too thin which gets broken easily.

It controlled diseases like malaria: Since this option talks about positive attribute of DDT, this option stands invalid. This chemical compound controls mosquitoes attacking the crop.

It caused harm to human populations: DDT causes vomiting, tremors or shakiness, and seizures

How would you identify a floodplain that has not been immersed for a long time?
ELEN [110]

Answer:

Floodplains are identified as zones on FEMA Flood Insurance Rate Maps (FIRMs). Flood zones are defined by type, depth, and frequency of flooding. But the shape and nature of a floodplain may also change over time as the main channel of a river naturally migrates through erosion and accretion, impacting how and where excess water may first over top the banks of the river during a flood event. Geologically ancient floodplains are often represented in the landscape by fluvial terraces. These are old floodplains that remain relatively high above the present floodplain and indicate former courses of a stream. I HOPE THIS HELPS YOU :)
