Facts About Troposphere and Tropopause

Troposphere is the lowest portion of Earth’s atmosphere and contains approximately 80% of the atmosphere’s mass and 99% of its water vapour and aerosols. The average depth of the troposphere is approximately 17 km in the middle latitudes. The characteristic ..

Atmosphere: Composition and Layers

Earth’s atmosphere is mainly consisted of nitrogen, oxygen, and argon, which together constitute the major gases of the atmosphere. The remaining gases are often referred to as trace gases. The below table shows the composition of Dry atmosphere. Composition of ..

How Tides are useful in Fishing?

Tides move water, bringing water in and taking water out. Understanding the cycles and effects of tides on fish helps in better fishing. The full and new moons normally create better fishing conditions because of the spring tides.  The reason ..

How Tides are useful in navigation?

Tidal flows as well as Tidal heights are of profound importance in navigation and very significant errors in position will occur if they are not taken into account. Many rivers and harbours have a shallow ” bar” at the entrance ..

Why there are no high low tides at Equator?

For any particular location, their height and fluctuation in time depends to varying degrees on the location of the Sun and the Moon, and to the details of the shape of the beach, coastline, coastline depth and prevailing ocean currents. ..

Tides: Meaning, Types, Duration, Frequency and Facts

Tides are a result of gravitational pull by both Sun and Moon, but the pull exerted by Sun is apparently weak. This is because of the larger distance as the gravitational force is inversely proportional to the square of the ..

Factors Affecting Ocean Currents

The main effect of temperature differences on the earth occurs in a north-south direction i.e. from equator to poles. Warm equatorial waters therefore move slowly along the surface towards the poles while heavier cold waters of the polar areas creep ..

Ocean Currents of Indian Ocean

The current systems of the Indian Ocean are largely controlled and modified by landmasses and monsoon winds. Indian Ocean being surrounded by the Indian subcontinent, Africa and Australia does not present most favourable conditions for the development of consistent system ..

Ocean Currents of Pacific Ocean

Important currents of the Pacific Ocean are as follows: North Equatorial Current (Warm) The north equatorial current originates off the western coast of Mexico and flows in westerly direction and reaches the Philippines coast after covering a distance of 7500 ..

Atlantic Ocean Currents- Equatorial, Gulf stream and other Currents

Important Currents of the Atlantic Ocean are as follows: North Equatorial Current (warm) North equatorial current is a significant Pacific and Atlantic Ocean current that flows east-to-west between about 10° north and 20° north. This current is generated because of ..
