give reasons
(a)There are two high tides and two low tides
(b)Warm currents produce amilder climate
(c)There is a heavy rainfall in queensland but the atacama desert is arid
(d)rich fishing grounds are located on the pacific coast of north america
Give reasons for what??

here is a good explanation for your tides question
http://www.whoi.edu/info/tides.html
Pacific coastal fishing grounds are no longer "rich". Your text is obsolete.
and our famous Newfoundland Grand Banks fishing region no longer has its vast abundance of cod.
Huge factory fishing ships from a certain country in Asia have depleted that as well.
Warm currents produce milder climate because they carry warm water which warms the air near it and the warm air again warms the land near it thus creating a milder climate
Because of periodicity of tides
(a) The occurrence of two high tides and two low tides in a day is due to the gravitational pull of the moon and the sun on the Earth's oceans. To understand this phenomenon, you can consider the following factors:
1. Gravitational Force: The moon's gravitational force has a significant impact on ocean tides. As the moon orbits around the Earth, it creates a tidal bulge on the side of the Earth nearest to it, causing a high tide. At the same time, there is another high tide on the opposite side of the Earth due to the centrifugal force resulting from the Earth and the moon's mutual gravitational attraction.
2. Rotation of the Earth: As the Earth rotates, different parts of the planet come under the influence of the tidal bulges, resulting in high tides occurring approximately every 12 hours. The points between the high tides experience low tides.
(b) Warm ocean currents contribute to milder climates in several ways. Here are some reasons:
1. Temperature Regulation: Warm ocean currents bring heat from the equator to cooler regions. This process helps to moderate the temperatures in areas influenced by these currents, making the climate milder than it would be without them.
2. Moisture Transport: Warm currents also transport moisture from regions of higher evaporation to regions with lower moisture content. This can lead to increased humidity and precipitation in areas where the warm currents flow, further contributing to a milder climate.
3. Wind Patterns: Warm ocean currents can influence wind patterns, which in turn affect the distribution of heat and moisture. These winds can help regulate temperatures, especially along coastal regions, creating a more pleasant climate.
(c) The heavy rainfall in Queensland and the aridity of the Atacama Desert can be explained based on the following factors:
1. Topography and Geography: Queensland is located in the northeastern part of Australia, where it receives a significant amount of rainfall due to its proximity to the coast and prevailing weather patterns that bring moisture-laden air masses from the surrounding ocean. In contrast, the Atacama Desert is located on the western coast of South America, where it is strongly affected by the cooling effects of the cold ocean currents (such as the Humboldt Current). These currents prevent moisture from reaching the region, resulting in arid conditions.
2. Rain Shadow Effect: Another factor influencing the difference in rainfall between the two regions is the presence of mountain ranges. Queensland benefits from the effect of mountains intercepting moisture-laden winds, causing them to rise and release rainfall on the windward side. The Atacama Desert, on the other hand, experiences the rain shadow effect, where mountains block moisture and create a dry zone on the leeward side.
(d) The presence of rich fishing grounds on the Pacific coast of North America can be attributed to various factors:
1. Cold Ocean Currents: The Pacific coast of North America is affected by cold ocean currents, such as the California Current and the Alaska Current. These currents are nutrient-rich and provide favorable conditions for the growth of phytoplankton, which forms the base of the marine food web. The abundance of phytoplankton attracts a variety of fish species, making it an ideal location for fishing.
2. Upwelling: Along the Pacific coast, prevailing winds and the rotation of the Earth cause upwelling. This brings nutrient-rich deep waters to the surface, providing an additional source of nutrients for marine life. The upwelling process enhances the productivity and supports a diverse ecosystem, including fish populations.
3. Coastal Geography: The shape and structure of the coastline play a role in the formation of favorable fishing grounds. The presence of reefs, kelp forests, and other types of underwater structures provide habitats for fish and other marine organisms, contributing to the overall productivity and attractiveness of the area for fishing.
It's important to note that these are general factors, and specific variations can exist due to local conditions and other factors that may influence each location differently.
