Clouds
Clouds are classified according to 3 criteria 
- Altitude
- Shape
- do they make precipitation

Cirrus - Thin, featherlike clouds. high in atmosphere. 
Stratus - Flat

Cumulus - White and fluffy, good weather

Nimbus - Rain cloud

Nimbostratus - Dark, Towering cloud that are also called                                                             " Thunderheads "

The effect of gravity on speed

1. Describe how the ball rolls off the ramp at each height-discuss the effect of bouncing or other factors.
Ans In case of small angle of the ramp. At starting position, the level of ball is not height. After we release the the ball. it roll off slowly at the begining and the speed will increase continuously. When it touch to the floor. The ball has some bouncing before change the direction to the horizontal. 
    If we increase the angle of the ramp. The level become higher.
the speed is faster when it touch to the floor. The ball has more bouncing before change the direction to the horizontal. 
    If we try to drop the ball at right angle of the ramp. The level become highest. Speed is fastest when it touch to the floor. The ball bouncing in the vertical direction.

                                                                                                        
2. Discuss what is fastest speed reached and any factors that could improve this.
Ans Speed of the ball is related to the height. We can increase the speed ny increase the height.

3. Does the ball travel in a straight line, why or why not?
Ans :  Most of the ball travel in straight line which there are 3 forms as follows;
1. Vertical direction because of gravity force.
2. Incline direction because of the angle of the ramp.
3. Horizontal direction because of it's guided by the floor.
However, there is not straight line traveling. It's curve direction during bouncing because of it combine between vertical and horizontal direction. It's called projectile.

Global Warming

Image result for world
          Global warming cause of humans don't help together to clear up pollution and garbage. Then, the World bad.    

       It effects for humans environment for eating habitation and working. 


                  Global warming 'cure' found by scientists.           A "technical fix" that could stop global warming by taking billions of tons of carbon dioxide out of the atmosphere and save the coral reefs from being destroyed by acidification has been developed by scientists.
