Question

a) State four factors that affect the movement of ocean currents. 1.How are Tides caused .

2.What is the time log between two high tides?​

Answer 1

Answer:

a) There are four factors affecting the origin and flow of Ocean Currents i.e. Rotation and gravitational force of the Earth; Oceanic factors (temperature, salinity, density, pressure gradient and melting of ice); atmospheric factors (atmospheric pressure, winds, rainfall, evaporation and insolation); factors that ..

1. The moon's gravity pulls the ocean toward it during high high tides. During low high tides, the Earth itself is pulled slightly toward the moon, creating high tides on the opposite side of the planet. Earth's rotation and the gravitational pull of the sun and moon create tides on our planet

2.12 hours and 25 minutes

Because the Earth rotates through two tidal “bulges” every lunar day, coastal areas experience two high and two low tides every 24 hours and 50 minutes. High tides occur 12 hours and 25 minutes apart.

Answer 2

Answer:

1. Temperature
2. Salinity
3. density
4. pressure gradien.

Tides are caused by the gravitational force exerted by the moon, and to a lesser extent the sun
