Lets talk about Weather!

Hi! Today i am going to talk about a new topic called "weather"

To start lets talk about types of clouds!

Types of clouds:

• Cumulus
• Nimbostratus
• Cumulonimbus
• Stratus
• Cirrus

Cumulus:

Cumulus Clouds

This are sample of cumulus clouds. Cumulus clouds are usually looks soft and fluffy like a cotton ball. It is located around 2000 meter in the atmosphere. 

Cumulonimbus Clouds

Cumulonimbus:

Stratus Clouds

This are sample of cumulonimbus.Cumulonimbus are formed when cumulus clods turns grey. It is located 1600 - 2000 meter in the atmosphere. This clouds could cause long steady rain.

Stratus:

Stratus clouds are located 2000 meter below the atmosphere. It is like a flattened sheets of clouds. It may stay over some place for sometime. This clouds cause overcast weather.

It looks like feathers right?

Cirrus:

Cirrus clouds are formed 8000 meter above the atmosphere. Cirrus Clouds looks like a feather.This Cloud could be seen even in a sunny day!

It's colour is dark grey

Nimbostratus:

This clouds are formed at a height of 2400 meter in the atmosphere. This cloud could bring a long and steady rain.

Since we are done talking about types of clouds. Now lets talk about other types of weather related things.

• Dew

Dew are formed when water vapor in the air comes in contact with a cold objects of a temperature at or below the dew point. The temperature at which droplets can from is called dew point.

• Hail

Hail is a form of precipitation that falls from the sky as clumps of ice. Precipitation is produced when water vapor from the sky condenses and falls to the ground because the clouds could not hold it anymore

This is how hail looks like

• Wind

To be exact wind cannot be seen. We can only feel it. Wind has its own negative and positive effects.

This Windmill could make wind

Positive effects

Wind could help the plants on doing the process called "pollination". Wind could also help us humans on our activities such as kite-flying and windsurfing. It also helps the animals to smell their prey.

Look at that people that use the wind to do windsurfing.

Negative effects

Its could cause tornadoes, hurricane, heavy rains and also it could cause floods.

This are a picture of a town/city when there are tornadoes.

• Land breeze and sea breeze

Wind is also formed when land and water are heated. Heating of land and water cause the formation of sea breeze at night and land breeze at day time.

That is all for now. Thank you for reading.

Human Population

Birth and Death rate

Human Population increases each day. We could even say every 3 minutes 1 or more babies are born around the world. Human Population increases everyday, every months and every year. Human population increases depending on the birth and death rate.
1. Birth rate:
Birth rate are the number of babies that are born each day, every hours and every minutes.
This are some factors that causes a high birth rate:

• Early marriages
• Lack of knowledge of birth control

2. Death rate:
Death rate are the number of people that died in the years and months. Death rate increases everyday, every months and every year. Human population decreases because / depending on the death rate.
This are some factors that causes a high death rate.

• Diseases
• Natural disasters
• Famine

Density
Human population is also measured by its density. When a place has many people living there the density will  increases.


Density may increases and decreases because of immigration and emigration. People who migrates is called migrants.


1. Immigration:
Immigration happen when people move from one country to another country / place. This action will increases the human population density. People who immigrates are called immigrants.


2. Emigration:
Emigration occurs when people move from the country to another country / place permanently. This action will decreases the human population density. People who emigrates are called emigrants.

Say NO to pollution!!

Soil Pollution

Plstics and trashes are thrown on the ground

This are samples of soil pollution that i took beside my church. Soil pollution may cause air and water pollution. The picture on the left shows about peoples that throws their trash on the ground. This action may contaminate the soil and damage the plants. When the plants cannot grow anymore the animal that is classified to herbivore will have nothing to eat. So if they have nothing to eat they could die. 

                                     Air Pollution

cigarette that has been used

The picture on the right shows about air pollution. In this picture I saw a  cigarette on the ground. This cigarette has been used and when its used that means smoke is coming out of it and it made air pollution. It also cause soil pollution since its not thrown in the right place. Air pollution may lead / cause to global warming. Air pollution can also cause diseases. Example of the diseases and other :

◦ Lung cancer

◦ Eye irritation

◦ etc.

The diseases  and eye irritation I mention is caused by air pollution. Example lung cancer: it is cause by inhaling smoke from the cigarettes and for eye irritation is caused by the dust and dirt from the street and etc.

Water Pollution

Water pollution can make the water in the water dirty. If the water is dirty animals like fish will die because the water is contaminated with oil from farm and factories, human waste, and others. This things could contaminate the water because when it is thrown in the water it will go to the water bodies and it will spread form one place to another. This days finding clean water is hard due to water pollution. Of course we as humans need clean water to survive if we don’t get enough water for our bodies we could suffer from dehydration and if we drink dirty water / water that has been contaminated it may cause diseases. Some people have did that because there are less clean water in their place. People like us, are lucky because we still can drink clean and healthy water.

We must say NO to pollution and say YES to save our mother nature! Because if we will not control our action soon earth will not be suitable for us to live and we all will have no future.
