- What direction does a low pressure system spin in the northern hemisphere?
The low-pressure system spins in the counter-clockwise direction in the northern hemisphere
- What direction does a high pressure system spin in the southern hemisphere?
The high-pressure system spins in the counter-clockwise direction in the southern hemisphere
- Where is the majority of fresh water found on earth?
The majority of the fresh water are found in the form of ice in the polar regions like Arctic and Antarctic areas.
- List three reasons why it is important that water molecules are polar.
- It contributes to the solvent nature of water in life
- Leads to hydrogen bonding that causes ice to float on water contributing to the life of the marine
- It causes cohesion and adhesion which contributes to biological functions of water
- As a sample of air is cooled, what happens to its relative humidity?
As air is cooled, the relative humidity rises as the water reaches the saturation point where the relative humidity will be 100%.’
- Is the water cycle an exogenic or an endogenic system?
Water cycle is exogenic because there are external factors, like human activities, which contribute to the cycle.
- List three ways that humans can mitigate the effects of hurricanes
- Conserving wetlands in the efforts of maintaining a lot of vegetation that reduce the effect of storm surges
- Avoiding construction in the hurricane zones
- Developing buildings that can endure the high winds
- Why are tropical cyclones (formed in the tropics) much more powerful than mid latitude cyclones (formed outside of the tropics)?
The mid latitude usually covers wider geographical than tropical cyclones, making it to lose much of its energy.
- When water condenses as a cloud forms, is energy absorbed or released?
There is release of energy. During the condensation, water releases energy that it absorbs during evaporation.
