Answer:
The weather represents the state of the atmosphere in a certain place, at a certain moment. <em>Usually, the weather is defined by evoking the most obvious characteristic of the atmosphere, so that it can be warm weather, cold or frosty weather, clear weather.
</em>
The characteristics that define the weather are the <u>meteorological elements.</u> These are:
- air temperature (expressed in degrees Celsius or Fahrenheit)
- air pressure (expressed in millimeters mercury column)
- wind direction and speed (wind direction is indicated by the cardinal or intercardinal point from which the wind blows, and the speed is expressed in m/s or km/h)
- nebulosity (the degree of coverage of the celestial vault with clouds, expressed in tenths of the visible celestial vault)
- the amount of precipitation represents the thickness of the water layer that would form if it stagnated on the earth's surface and is expressed in liters / m² or mm
Answer:
Rays of light emanate from a real image, but only appear to do so from a virtual image.
Explanation:
- The real images are inverted to the object and rays of light are emitted from the virtual object tends to do so and this image is always bigger than the object.
- Thus a real image occurs where the rays of light converge and a virtual Image occurs when the rays of light diverge and a virtual image can't be projected to a screen as compared to a real image.
Question: Which statement best explains why Earth’s outer core is in liquid form?
The iron-nickel alloy melts due to hot temperatures.
The outer core has a tarry consistency.
This region is less dense when compared to the mantle.
This region is under extreme pressure from the weight of other layers.
Answer:
The statement here that bet describes the Earth's outer core is in liquid form " The iron-nickel alloy melts due to hot temperatures."
Explanation:
The outer core of the Earth's is made up of fluid layer which is about 2400 km thick and basically made from iron as well as nickel alloy. This layer lies just above the solid inner core and below it mantle is present. The core of the Earth works like a furnace for the whole composition. It holds the intense heat as well as pressure that helps is maintaining the iron and nickel in the molten state.
