Arabian Gulf is a marginal and closed sea
T/F?
F, semi-enclosed
Why Arabian Gulf is characterized by extreme environmental conditions?
- High-latitude geographical position,
- High temperature fluctuation and high evaporation rates, which results in
- High salinities,
- Wide wind fluctuations.
- Salinity can exceed …. psu
- may reach ……… psu in tidal pools and lagoons.
- 43
- 70-80
Gulf of Salwa is located between
Saudi Arabia and the Qatar
solubility of oxygen in seawater ……… with increasing salinity
decreases
Are caused by gravitational forces from the moon and sun.
Tides
the movement of water that occurs on the surface of water bodies
Waves
Powerful wave can also be formed as a result of :
- earthquakes
- landslides
- volcanic eruptions.
are the rise and fall of sea levels or the difference between the crests and troughs.
Tides
The large masses of water moving in a specific direction from one location to another are
Currents
The deep-ocean currents are driven by differences in the water’s density, which is controlled by temperature (thermo) and salinity (haline).
Thermohaline circulation
Arabian Gulf is connected with the adjacent Indian Ocean by a narrow passage at …..
the Strait of Hormuz
Generally higher salinity occurs within the coastal waters and …….. offshore.
decreases
Generally higher salinity occurs within the coastal waters and …….. offshore.
decreases
results in frequent and thorough mixing of the entire water column and vertical temperature gradients are usually small especially in coastal waters.
Strong wind
