Dovator [93]3 years ago

The Earth has a long history that stretches back over 4.6 billion years ago when bodies of rock began to collide together and form larger rocks in the process. The Earth was the product of these rock collisions, and when the Earth was formed into a planet it was extremely hot for several reasons.

Internal pressure helped to raise temperatures from the gravitational contact of these large rock collisions. There were also large amounts of radioactive elements early in the history of our planet that released heat through radioactive decay. The other reason is tied into the first, with multiple rocks and asteroids were colliding with Earth and these large bodies traveled at tremendous speeds through space which created immense heat on impact with Earth.

Distances for latitude are in _____ degrees or _____ of the equator.
Brilliant_brown [7]

Answer:

Distances for latitude are North degrees or South of the Equator.

Explanation:

Latitudinal lines are imaginary lines created by humans to serve their needs. These lines run from east to west as closed lines, or rather circles. Their starting point is the Equator which marks the middle part of Earth, and they spread from it in a northern and southern direction until the poles.

The Equator is at 0 degrees of latitude, and as mentioned it is the starting point for measuring all of the other latitudinal lines. There are latitudinal lines that stretch until 90 degrees North and 90 degrees South. The purpose of these lines is to help in orientation and to help with the absolute location of any place on Earth (in combination with the longitudianl lines). Also, they are very good in roughly representing the climate zones on Earth, the amount of sunlight a place gets, and dividing the globe into Northern and Southern Hemispheres.

How does the European Union work to unify Europe and still protect national and local autonomy?
steposvetlana [31]

Answer:

The EU is based on the rule of law. Everything the EU does is founded on treaties, voluntarily and democratically agreed by its EU countries. Law and justice are upheld by an independent judiciary. The EU countries gave final jurisdiction to the European Court of Justice which judgements have to be respected by all.

1. Describe the various types of air masses and how they interact to form the four frontal types. Also include the general weath
grandymaker [24]

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.
