Secrets of Snow | Compilation

The video explores the science behind snowflakes, including their unique shapes and the role of temperature and humidity. It delves into the influence of bacteria on precipitation, the formation of the Athabasca Dunes, and the historical significance of Camp Century in climate research. Additionally, it highlights how bats use snow dens for hibernation and explains the rare weather phenomenon of thundersnow.

What is the primary factor that determines the shape of a snowflake?

• Altitude

• Wind speed

• Temperature

• Humidity

Why are snowflakes typically flat hexagons?

• Influence of atmospheric pressure

• Effect of sunlight on snow

• Because of the molecular structure of water

• Due to the Earth's magnetic field

What is the term used for the process where microbes act as condensation nuclei?

• Bioaccumulation

• Microbial condensation

• Microbial nucleation

• Bioprecipitation

What role do bacteria play in the formation of snowflakes?

• They increase the temperature of snowflakes

• They prevent snowflakes from melting

• They provide nutrients for snowflakes

• They act as condensation nuclei

Which of the following is NOT a factor in the formation of the Athabasca Dunes?

• Glacial retreat

• Volcanic activity

• Sediment deposition

• Wind erosion

What unique feature is found in the Athabasca Dunes?

• Volcanic rocks

• Rare animal species

• Underground rivers

• Endemic plant species

What was the primary scientific contribution of Camp Century?

• Development of nuclear energy

• Study of polar bear habitats

• Discovery of new plant species

• Collection of the first long ice core

What was a major challenge faced by Camp Century?

• Melting ice causing structural issues

• Lack of food supplies

• Frequent polar bear attacks

• Inadequate communication systems

What is a key difference between summer thunderstorms and thunder snow?

• Summer storms have taller clouds

• Summer storms are quieter

• Thunder snow occurs only at night

• Thunder snow is caused by volcanic activity

What is a common condition for the occurrence of thunder snow?

• Strong solar activity

• Presence of volcanic ash
