As water vapor builds up in the winds blown towards mountains, they are forced to rise and the temperature drops. The water condenses into clouds at these higher altitudes. This is why mountain peaks are often seen to be surrounded by layers of cloud.

How does rain cause Rockslides?
The reason we get rockslides after heavy rain is because the rainwater enters cracks in the rock where as it freezes, it expands and opens the crack wider. As the thaw starts, the pieces of rock splinter and separate from the main rock. Loose rock is continuously building up on […]
How are Mountains formed?
All mountains are formed as result of violent changes in the Earth’s surface, most of which happened millions of years ago. Folded mountains were made of rock layers that had been squeezed by great pressure into large folds. In dome mountains, the rock layers were forced up to make great […]
How are Waterfalls formed?
Water erodes soft rock, such as sandstone or shale much more easily than hard rock such as granite, so where the course of a river goes over both these types, the upper layers of soft rock will be worn away more quickly, and the water will drop down from the […]
How are Rivers formed?
Rivers are formed over thousands of years, as excess rain and melted snow or ice from glaciers makes its way from the land to the sea. Water drains though the ground into small streams, which join up with others as they flow downhill, eventually forming a river in the bottom […]
How does a Whirlpool form?
Whirlpool occur when two opposing currents meet. They cause the water to spin round and round very rapidly. Huge whirlpools at the sea are normally caused by powerful tides. The most famous whirlpool is the Maelstrom, which appears between two islands off the coast of Norway. sometimes this whirlpool is […]
How are Waves formed?
It is noticeable that on a calm day, there are very few waves, but on a stormy or windy day there are many waves. This is a result of a combination of the wind and the shape of the seabed. The wind blows the surface layers of the sea, gradually […]
Why do you feel Jet Lag?
When people travel long distances by fast jet plane, they often get a confusion which is known as jet lag. The reason for this is because the modern aircraft travels so fast that they may cross several time zones in a short time during a flight. The cause of jet […]
Why does the Sky appear Blue in color?
Sunlight reaches Earth’s atmosphere and is scattered in all directions by all the gases and particles in the air. All light travels in a straight line unless something gets in the way and does one of these things:— reflect it (like a mirror) bend it (like a prism) or scatter […]
