FROGS vs. TOADS

Many people don’t know the difference between frogs and toads. They are quite different animals, although they belong to the same animal group.

GET DIFFERENCE BETWEEN FROGS AND TOADS

Frogs:

Need to live near water

Have smooth, moist skin that makes them look “slimy”.

Have a narrow body

Have higher, rounder, bulgier eyes

Have longer hind legs

Take long high jumps

Have many predators

Toads:

Do not need to live near water to survive

Have rough, dry, bumpy skin

Have a wider body

Have lower, football shaped eyes

Have shorter, less powerful hind legs

Will run or take small hops rather than jump

Do not have many predators. Toad’s skin lets out a bitter taste and smell that burns the eyes and nostrils of its predators, much like a skunk does.

And neither frogs nor toads will give you warts! That is just a myth.

Dust is a collection of microscopic particles of material. Dust is heavy enough to see and light enough to be carried by the wind.

Dust can be made up of pollen, bacteria, smoke, ash, salt crystals from the ocean, and small bits of dirt or rock, including sand. Dust can also contain tiny fragments of human and animal skin cells, pollution, and hair.

When its windy outside, you can see dust particles blowing through the atmosphere. Large amounts of dust that are carried through the atmosphere by strong winds are called dust storms. Dust storms mostly occur in dry, open areas.

The Sahara Desert in Africa has many dust storms. Most Sahara dust is made of sand. Dust storms in the Sahara Desert can blow a wall of dust as high as one mile off the ground. Dust storms can make it very difficult to see and breathe.

In 1983, a dust storm covered the city of Melbourne, Australia. The deserts of Australia were experiencing drought, so sand and soil were loose. The dry conditions allowed about 50,000 tons of material to erode as dust. Melbourne had more than 1,000 tons of dust dumped on it. The dust caused so much damage that it took years of work and millions of dollars to repair.

In some areas, windblown dust settles into deposits called loess. Loess is a type of sediment that is loose and fragmented. It can be many meters deep. Loess often develops into fertile soil for agriculture because it retains water, allows many different plants to take root, and has abundant nutrients.
