The resources we get from our nature is called natural resources. This resources are limited. So, we have to conserve them.
To conserve our natural resources -
1. We should create awareness among the people.
2. The government should enforce law and order to protect the natural resources.
3. We should not misuse our natural resources.
Thus, we can conserve our natural resources.
To me the job of the judge at the cort seems the hardest. Those who break the law, do crimes and disturbs the social peace are caught by the police and put forward to the judge for judgement. The judge listens to the both plaintiff and criminal . He punishes the criminal accordingly to the law. A small mistake made by the judge can convict an honest man and release a criminal.
This is why I think the job of the judge is the hardest.
Dinosaurs were animals that lived 100 million years ago. Some dinosaurs were more like reptiles while others were more bird-like. Although many creatures are sometimes called dinosaurs, dinosaurs did not fly or live in the ocean.
Kingdom:Animalia
Phylum:Chordata
Class:Reptilia
Superorder:Dinosauria
What did they eat?
Most dinosaurs lived off of plants, but some were carnivores and ate meat. The carnivores have become famous in the movies like Jurassic Park. The T-Rex and the Velociraptor are two of the scary carnivores.
How do we know about dinosaurs?
We know about dinosaurs from fossils that are found in the ground. From fossils, scientists are able to recreate whole skeletons of dinosaurs and determine what the dinosaurs were like. Some of these fossils and skeletons can be seen in museums. Fossils of dinosaurs have been discovered on every continent of the world. Fossils from the same type of dinosaur have been found on different continents as well.
Were they all big?
Dinosaurs, in general, were very large. Some dinosaurs are thought to have been 40 feet tall or more. This is twice as tall as the tallest giraffe ever. There were also some smaller dinosaurs that were just a foot or so tall. There were a wide variety of dinosaurs from giant lumbering plant eaters that walked on four legs to fast dangerous meat eaters that could run on two legs.
Why did they go extinct?
Well, scientists aren't 100 percent sure, but many think that the dinosaurs went extinct when a giant meteorite hit the Earth. When the meteorite hit, it sent up dust and dirt into the sky covering up the sun for a really long time. This caused all the plants to die, and soon the dinosaurs died too.
Biggest, Fastest, Tallest
There is a lot of debate on which dinosaur is the biggest, smallest, smartest, etc. We don't know for sure, but we can take a good guess using the latest information from paleontologists.
Biggest - The biggest dinosaur we currently know about is the Argentinosaurus. Paleontologists estimate it weighed up to 100 tons and measured 120 feet long.
Smallest - The Microraptor may be the smallest dinosaur ever. It was only about 16 inches long, about the size of a pigeon.
Biggest carnivore - The really big dinosaurs were all herbivores, but the biggest one that ate meat was the Spinosaurus. It weighed around 8 tons. The T-rex was one of the biggest carnivores as well.
Smartest - We don't really know for sure how smart dinosaurs were, but best guess is that they weren't very smart. However, the smartest was likely the Troodon. It is thought that the T-Rex was pretty smart for a dinosaur as well.
Dumbest - The stegosaurus was likely one of the dumbest dinosaurs. It was a giant animal with the brain the size of a ping pong ball.
Fastest - The Ornithomimus was likely a very fast dinosaur. It was a lot like an ostrich and probably ran as fast, or faster, than an ostrich at speeds of 40-50 miles per hour.

What is a glacier?
A glacier is a thick mass of ice that covers a large area of land. Around ten percent of the world's land area is covered by glaciers. Most glaciers are located near the North or South Poles, but glaciers also exist high in mountain ranges such as the Himalayas and the Andes.
How do glaciers form?
Glaciers form from snow that doesn't melt even during the summer. When enough snow builds up the weight of the snow will compress and turn into solid ice. It can take hundreds of years for a large glacier to form. Glaciers Move Although glaciers are made of ice and appear to be sitting still, they are actually moving. The weight of a glacier will cause it to move slowly downhill, sort of like a very slow moving river. The speed of glaciers varies widely with some moving as slow as a few feet a year while others may move several feet per day.
Types of Glaciers
Scientists have given names to different types of glaciers. Here are a few of the main types: Calving -
A calving glacier is one that ends in a body of water like a lake or an ocean. The term calving comes from icebergs that break off the glacier or "calve" into the water. If the body of water has tides (like the ocean), the glacier may also be called a tidewater glacier. Cirque - Cirque glaciers form on the slopes of mountains. They are also called alpine or mountain glaciers. Hanging - Hanging glaciers form on the side of a mountain above a glacial valley. They are called hanging because they do not reach the valley where the main glacier is located. Ice cap - An ice cap is formed when ice completely covers an area of land such that no part of the land, not even mountain peaks, poke through the top of the ice cap. Ice field - An ice field is when ice completely covers a flat area. Piedmont - A piedmont glacier is formed when a glacier flows into a plain at the edge of a mountain range. Polar - A polar glacier is one that is formed in an area where the temperature is always below the freezing point. Temperate - A temperate glacier is one that coexists with liquid water. Valley - A valley glacier is one that fills a valley between two mountains.

What are salts?
In chemistry, salts are ionic compounds that are formed from the neutralization reactions of an acid and a base. Salts have certain properties:Salts are made up of an equal number of anions (negative ions) and cations (positive ions)They are hard and brittleMost salts dissolve in water and are solids at room temperatureThey have strong bonds and a relatively high boiling pointSalts are electrically neutralIn their solid state, they arrange themselves in a rigid structure called a latticeSalts come in a variety of tastes and colors. Some salts are not safe to eat.
Table Salt
What most people call "salt" is the chemical compound sodium chloride. It has the chemical formula NaCl. Sodium chloride dissolves in water and is what makes the ocean water salty.
Salt is necessary for animal life. It is also used to enhance the taste of our foods and to preserve foods.
Soap is a Salt
In chemistry, soap is a type of salt. This is because it is formed from the mixing of an acid and a base.
How does soap work?
Soaps and detergents help to clean clothes, skin, dirty dishes, and other items by dissolving grease. Detergents are made up of special molecules. Part of these molecules is attracted to water. The other part is attracted to grease. The part that is attracted to grease will dissolve the grease and break it up into smaller components that can then be rinsed away by water.
How is soap made?
Humans have made soap all the way back to the ancient civilizations of the Babylonians and the Egyptians. For many years soap was made from a mixture of ashes, animal fat, and water. Although we no longer make soap the same way, the chemistry for making modern soap is very similar.
Today soap is often made from a combination of fats and sodium hydroxide. As the soap is formed, the byproduct of glycerol is removed. Once the raw soap is produced, other ingredients like perfumes and colors can be added. The chemical process used to make soaps is called saponification.
Interesting Facts about Soaps and SaltsSalts can be made by mixing an acid and a base or an acid and a metal.Thallium salt was once used as rat and ant poison.The green color of an emerald is because of small amounts of the salt chromium oxide.Around 250 million tons of salt was produced in 2010. Most of it is produced by the evaporation of ocean water and salt lakes.Glycerol, the byproduct of soap manufacturing, is used for making other chemical compounds such as plastics and explosives.Several different salts go into the manufacture of glass.Liquid soap was not invented until the late 1800s.Soap is a key ingredient in many lubricating greases.
