Why do we have different seasons?

Why do we have different seasons?

Why do we have different seasons?


Since earliest times, man has been curious about the changing of the seasons. There are a lot of questions. Why is it warm in summer and cold in winter? Why do the days gradually grow longer in the spring? Why are the nights so long in winter?
In ancient times people thought that Gods were changing the weather and the seasons.
As we know now the earth revolves around the sun, and at the same time it revolves on its own axis. The axis of the earth isn’t at right angles to the path of the earth around the sun. The reason for this is a combination of forces: the pull of the sun, the pull of the moon, and the spinning action of the earth itself. The earth goes around the sun in a tilted position. It keeps that same position all year, so that the earth’s axis always points in the same direction, toward the North Star.

Spring is wonderful

Spring is wonderful

Spring is wonderful

In spring nature reawakens and the world looks renewed, fresh and filled with joy. The weather gets warmer, and as the snow thaws long icicles glitter in the sun. The rooks, the first spring birds, have come back from the warm countries and are making nests in the trees. The air is fresh. The sky comes blue and great white clouds drift over it. The first flowers appear, the grass sprouts and shoots up visibly. The sun grows warmer and warmer and as the snow melts under the bright sunrays brooklets begin to run. Rivers and lakes begin to melt and cracks.
Spring is the first season of the astronomical year, coming between winter and summer. Its start can be precisely defined astronomically. The ecliptic, the plane in which the sun seems to revolve around the earth and in which the earth really revolves around the sun, is divided into four 90 sections, each beginning with a definite point: two solstices and two equinoxes. The amount of time taken by the sun to cover each of these divisions is termed a season.

Coffee – world’s favorite cup

Coffee – world’s favorite cup

Coffee is one of the world’s most valuable agricultural crops. The coffee tree is native to Ethiopia. The name coffee also refers to the fruit (beans) of the tree and to the beverage brewed from the beans. In Africa, coffee beans were consumed as food and later made into wine. Coffee beans were introduced to Europe during the spice trade (fifteenth century).
Today, Brazil and Colombia are the world’s leading producers of coffee beans.
Coffee is among what historian Sidney Mintz called the “drug foods” of the Americas and other tropical zones; these foods also include tea, chocolate, tobacco, rum, and sugar.
Coffee grows as a bush with sweet-smelling flowers and fleshy fruit called “coffee cherries.” Within the fruit are two seeds, or beans. There are at least 60 types of coffee plants. But only two kinds, called Arabica and Robusta, are in great demand.

Butterflies – flying flowers

Butterflies and moths are insects, and like all insects they have three pairs of legs. Their bodies are divided into three sections: head, thorax, and abdomen. Most butterflies are active during daylight, while moths are mostly nocturnal.
Butterflies live throughout the world, except in Antarctica.
Nectar from flowers is an important part of their diet. Some will eat mosses and ferns. Others like cones, fruits, and seeds, but some do not eat at all and live for only a short time!
Butterflies and moths change form completely over the course of their lives. This change is called metamorphosis. First, they hatch from an egg as a larva, or caterpillar. Caterpillars have no wings, and they often look like fat worms. Some kinds are hairy.

The drink that cheers

The drink that cheers

The drink that cheers

Tea is said to be the most common drink in the world, with production exceeding two million tons per year worldwide.
Tea is a strong and energizing drink. It is made by soaking the leaves of the tea plant in hot water.
Tea was first drunk many centuries ago by the Chinese. The story goes that some leaves from a tea bush fell by chance into the boiling water in a philosopher’s pot. In the past, tea was affordable only by the rich, because of the high cost of importing it. Wealthy households would lock it securely away in sturdy tea chests to prevent theft.
Tea is thought to be native to China and/or Tibet, but not to India or Sri Lanka, where most commercial tea is grown today.
Commercial teas are generally of two forms—black or green—with black by far the more common.

Interesting facts about trees

Interesting facts about trees

Trees and other plants release the oxygen that we breathe; prevent soil erosion; provide food and shelter; and provide material for human use, such as paper, medicine, tools, weapons, and even toys. They are also the dominant plants in the world’s forests, and thus provide critical habitats for the other species which live there.
Trees have great economic significance to humans as a source of food, building materials, and paper. Almond, coconut, cherry, prune, apple, peach, pear, and many other tree species are grown in orchards for their fruits and nuts.
Wood is used as a construction material and to make furniture.
Trees exist as an element in many legends and myths worldwide. They are often used as a symbol for life. The Druids frequently worshipped and practiced their rites in oak groves, whereas some ancient pagans worshipped the trees themselves.

Deadly plants

Upas Tree

Upas Tree


Our world is covered with plants, and we are surrounded by them. There are many poisonous plants.
The best way to avoid accidental poisoning from plants is knowledge and prevention.
No bird flies near, no tiger creeps; alone the whirlwind, wild and black, assails the tree of death and sweeps away with death upon its back.
A. S. Pushkin, The Upas Tree
