REPORT
TEXT
The betel plant is a slender,
aromatic creeper, rooting
at the nodes. The branches of the plant are swollen at
the nodes. The plant has alternate,
heart-shaped, smooth, shining and long-stalked leaves,
with pointed apex. It has five
to seven ribs arising from the base; minute flowers and
one-seeded spherical small
berries.
Betel is a native of central and
eastern Malaysia. It spread at a very early date throughout tropical
Asia and later to Madagascar and East Africa. In India, it is widely cultivated
in Tamil Nadu, Madhya Pradesh, West Bengal, Orissa, Maharashtra and Uttar Pradesh.
The use of betel leaf can be traced as far back as two thousand years. It is described
in the most ancient historic book of Sri Lanka, Mahavasma, written in Pali.supari)
to guests in Indian subcontinent is a common courtesy.
Recent studies have shown that betel
leaves contain tannins, sugar and diastases and an essential oil.
The essential oil is a light yellow liquid of aromatic odor and sharp burning
in taste. Betel also has powerful antiseptic properties since it contains
chavicol. The
alkaloid arakene in it, has properties resembling cocaine in some respects.

Stalactites and stalagmites are
unique natural appearances.
They occur in limestone caves. The
stalactite is above, and hangs downward like an icicle. Meanwhile, the
stalagmite is below and sticks up. They grow in pairs, the slightly acidic
water dissolves some of the limestone, carrying it downward.
Sometimes
the stalactites are missing, as they sometimes break off and fall. Or
human visitors may break them off, and take them away. Often, the stalactite
and stalagmite will connect, and become a column.
The
flow of water, slightly acidic from acid rain or from passing through something
acidic, is what digs out the caves. It essentially widens cracks in the rock.
And the ceiling may also collapse, making a mound of limestone on the floor, and
a concave dome above.

The Sun
The
sun is the largest object
in the solar system. It contains more than 99.8% of the total mass of the
Solar System. It is often said that the sun is an "ordinary" star.
That's true in the sense that there are many others similar to it. But there
are many smaller stars than larger ones; the Sun is in the top 10% by mass.
The median size of stars in our galaxy is probably less than half the mass of
the Sun.
The
sun is, at present, about 70% of hydrogen and
28% helium by
mass everything else ("metals")
amounts to less than 2%. This changes slowly over time as the sun converts
hydrogen to helium in its core.
The outer layers of the Sun exhibit differential rotation: at the
equator the surface rotates once every 25.4 days; near the poles it's as much
as 36 days. This odd behavior is due to the fact that the sun is not a solid
body like the Earth. Similar effects are seen in the gas planets.
The differential rotation extends considerably down into the interior of the
sun but the core of the sun rotates as a solid body.
Conditions
at the Sun's core (approximately
the inner 25% of its radius) are extreme. The temperature is 15.6 million
Kelvin and the pressure is 250 billion atmospheres.
At the center of the core the sun's density is more than 150 times that of
water.
The
sun's power (about 386 billion mega Watts) is produced by nuclear fusion reactions.
Each second about 700,000,000 tons of hydrogen are converted to about 695,000,000
tons of helium and 5,000,000 tons (=3.86e33 ergs) of energy in the form of
gamma rays. As it travels out toward the surface, the energy is continuously
absorbed and re-emitted at lower and lower temperatures so that by the time
it reaches the surface, it is primarily visible light. For the last 20% of
the way to the surface the energy is carried more by convection than
by radiation.

Weather is the state of
the atmosphere in a certain place
at a certain time. Weather always changes and is different all around the
world. It depends on many
elements. It may be warm and sunny in one place but cold, windy and rainy
somewhere else. Climate refers to
the weather conditions in a certain area over a longer period of time.
Weather is important to everyone. It affects our
daily lives in many ways What we wear depends on the
weather. Weather affects the way plants and crops grow.
Extreme weather
may lead to dangerous situations. Hurricanes and storms may even kill people
and destroy houses
and roads.
Our weather is made in the
troposphere—the lower layer of
the atmosphere. Our atmosphere consists of 78% nitrogen and
about 21 % oxygen.
Water vapor in
the atmosphere produces clouds, rain, snow and fog.
