Environmental Phenomena and Their Effects

The video explores various unusual weather phenomena, including blood rain, black rain, black blizzards, volcanic tornadoes, and heat bursts. Blood rain is often caused by dust or algae, while black rain results from pollution or nuclear fallout. Black blizzards were extreme dust storms during the Dust Bowl era. Volcanic tornadoes form from pyroclastic flows, and heat bursts cause sudden temperature spikes. These phenomena highlight the diversity and complexity of Earth's weather.

What is the primary cause of the red color in blood rain?

• Actual blood falling from the sky

• Dust from deserts

• Microscopic algae

• Volcanic ash

Which microalgae was responsible for the blood rain in Spain?

• Chlorella vulgaris

• Spirulina platensis

• Trentepohlia annulata

• Haematococcus pluvialis

What was a major cause of black rain during the 19th and 20th centuries?

• Nuclear tests

• Burning coal

• Volcanic eruptions

• Forest fires

What event in 1945 led to black, radioactive rain?

• Chernobyl disaster

• Three Mile Island accident

• Fukushima disaster

• Hiroshima and Nagasaki bombings

What was the primary environmental condition that led to the Dust Bowl's black blizzards?

• Excessive rainfall

• Soil mismanagement

• Volcanic eruptions

• Deforestation

What respiratory condition was caused by the Dust Bowl's black blizzards?

• Dust pneumonia

• Bronchitis

• Emphysema

• Asthma

What is a key difference between volcanic tornadoes and regular tornadoes?

• Volcanic tornadoes last longer

• Volcanic tornadoes are caused by thermal convection

• Volcanic tornadoes form from colliding air masses

• Volcanic tornadoes are larger

What phenomenon involves a sudden temperature increase during the night?

• Heat wave

• Warm front

• Heat burst

• Cold front

What typically initiates a heat burst?

• A heat wave

• A volcanic eruption

• A thunderstorm

• A cold front

How does air pressure affect a heat burst as it descends?

• It causes the air to expand

• It heats the air back up

• It cools the air further

• It has no effect
