Transcript of Sensational Seasons

Olivia Mann Sensational Seasons This presentation will explain the cause of the seasons that we experience and their effect on agricultural farming and practices. For the purpose of this presentation I will focus on banana growth and production. Introduction Seasons Explained The Earth's axis is on a tilt of 23.5 degrees. This tilt and the rotation of the Earth as it orbits around the Sun causes seasonal changes. Summer in the Northern Hemisphere means that its Winter in the Southern and vice versa. If the axis of the Earth was not tilted, the seasons would be similar and some areas of the Earth would not receive much sunlight. Australia's Seasons
Summer: December-February
Autumn: March-May
Winter: June-August
Spring: September-November Seasons and their effect The seasons we experience influence our lives daily. It can effect what clothes we wear each day because of the temperature. It can effect what activities we do, because of the weather. It also has an impact on the availability of fruit and vegetables for us to eat. Most fruits and vegetables are grown during the seasons that suit their growth needs. Australia can also import goods to ensure a steady stream of fresh food all year round. Bananas best grow in temperatures of 26-30 degrees. This suits the Australian climate especially in Northern Queensland, South-East Queensland and Northern NSW. Bananas can be grown all year round in some areas but are best in April, May, June, August, September and October as shown above. More than 90% of Australia's bananas are grown in Queensland and are a product of the rain and sunshine of the tropics. Temperatures here rarely drop below 26 degrees and the seasons are less defined than other areas. Banana Production The constant warm temperature of the Northern tropics is directly related to the Earth's tilt and direct sunlight to this area. Being closer to the equator means warmer weather all year round, bananas thrive in this environment. Bananas Development This presentation has informed you about the relationship between the Earth's movement, tilt and the seasons. It has focused on banana production and how Australia's climate in some areas is ideal for their growth.
