Answer:
Convection currents generated within the asthenosphere push magma upward through volcanic vents and spreading centres to create new crust.
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
A sky map is created by astronomers to identify, name, and plot celestial objects it is a map of the sky made by dividing the celestial sphere into 88 different areas.

Answer:
Conditions at the base of a glacier increase glacial flow velocity -
Steeper slope
Smooth rock / glacier contact
Colder basal water temperature.
Explanation:
Steeper slope and smooth rock/glacier contact will increase glacial flow velocity because higher the steepness higher the velocity and smoothness will apply less friction.
Due to decrease in ice thickness the load at the bottom of the glacier will decrease, and we know that the glacier flows under the load of itself, so lesser the load lesser the velocity.
Colder basal water temperature will generate less amount of melt as compared to warmer basal water temperature, so in colder condition, glacial flow velocity will not be increased.
