Seasons What Causes Seasons?
Earth’s seasons are caused by the 23.5 degree angle on its rotational axis. In autumn and spring neither hemisphere is significantly leaning more or less directly towards the Sun. A Change in the Earth's tilt If the Earth was tilted at a 0 degree angle there would be NO seasons. The same might go for people who live at the bottom tip of New Zealand and possibly Tasmania. If the world was tilted at an angle like this the people that live at the tip of Greenland or Russia or places around that top area would have to migrate closer as it could be too cold for them to live permanently. This tilt causes the hemispheres to receive different amounts of the Suns energy. The hemisphere leaning more directly towards the Sun has summer and the hemisphere leaning less directly towards the Sun has winter. The sun would still hit the Equator but neither the Northern nor Southern Hemisphere would be facing more or less directly towards the sun. The North and South Pole would always be darkness instead of 6 months in light and 6 months in darkness. All places around the world would always be around or the same temperature, it would not vary significantly. Mangoes Seasons, weather and climate can impact on the production of Mangoes because they are strictly a tropical fruit. They love the tropics. The best climate to grow mangoes is frost free, with cool, dry winters and steamy, hot summers. Mangoes like growing in light and free draining soils, they don't need rich soil. But best of all, mangoes are one of the most versatile fruits on the market; delicious as a healthy snack on their own, a perfect addition to your favourite chicken and prawn dishes, light summer salads, smoothies and sweet desserts. Mangoes have a boring life cycle. They begin by growing on a Mango Tree and start blossoming in late spring. It depends on how early you plant your tree and it starts growing mangoes as how early or late your mangoes will be ripe. Of course after they are ripe enough humans come along and pick them off the tree and eat them Mangoes begin their life cycle again when the new season comes around and they start blossoming on their own. Farming and Agricultural Practices This can help farmers understand what season to plant and harvest their crops and what weather conditions the crops like best. Farming has improved by understanding what seasons crops best grow in. Some fruits, veggies and grains need dry, cool weather such as late autumn and all of winter to grow best while others need wet, hot weather such as late spring and all of summer to grow best. Understanding what climate, seasons and weather mangoes best grow in is essential for them to grow big and juicy. If the Earth was tilted at a 0 degree angle mangoes would become a year-round product because farmers would choose a piece of land situated where mangoes grow best and as it would always be around the same temperature they would always grow.
