The time gap between spring and neap is approximately 7 days. The neap tides refers to a period of moderate tides when the sun and moon are at right angles to each other. The spring tides are high tides.
The Stratosphere is the layer of the Earth’s atmosphere which lies beyond the troposphere. It extends up to an altitude of 50 kilometres from the earth’s surface. This layer is almost free from clouds and associated weather phenomenon. It therefore makes conditions most ideal for flying aeroplanes.
