Answer:
1. chemical properties
2. physical properties
Explanation:
1. chemical properties
2. physical properties
Since ,
Earth is distributed into two ways i.e. - chemically or mechanically.
By chemically ,
The Earth is composed of the crust, the mantle and the core whereas ,
By mechanically or ( by the state of liquids) ,
The Earth is divided into different spheres , i.e. , the lithosphere, asthenosphere, mesospheric mantle, outer core, and the inner core.( which is based on physical properties )
Race doesnt exist and ethnicity is where youre from.
Answer:
Fronts are defined as body of two air masses and are of four types.
Explanation:
Air masses always be in motion which brings different types of weather. Transition between the two air masses is a front.Basically there are four different types of fronts and the weather which are associated with them also varies.
So the four fronts are:
- WARM FRONT: It has a wide range from 10-100km.Winds move easterly before the front passes.Chances of rainfall increases when the front cloud approaches . And the wind starts blowing southwesterly or southerly and then the temperature becomes warm with the clouds cleared. Has a huge amount of humidity.
- COLD FRONT: It is narrow down to a range of <1km.Over a short distance Temperature changes when cold air advances and warm air displaces.Moisture change also causes sharply. At the ahead of the front their is higher moisture content and behind it is lower.
- OCCLUDED FRONT: When a cold front catches up with a warm front. Their are both cold and warm occulusions. In a warm occulusion colder air is found behind the front and conversely in cold occulusion warmer air is found at the front end. Winds blow either fromsouth or east. And then it gets shifted from west or northwest.
- STATIONARY FRONT: Boundary between warmer and colder front doesn't move. Precipitation may get developed.
- Finally the context of midlatitude cyclogenesis leads to understanding the different type of fronts which helps us to know the kind of weather and the knowledge help us to predict how the areas near the fronts will be impacted regardless of precipitation' wind and temperature.
The countries in the Middle East are oil rich, so they are profiting offf oil. China and Malaysia are rich because they make clothing and other needs and ship them over here. Bangladesh profits off making clothing like weavings, but has lost lots of money in previous years due to flooding.
