There are three kinds of rock: igneous, sedimentary, and metamorphic. Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water.
One simple and easy way that scientists can accurately date fossils found is through the ground levels. When you take a big chunk out of the earth, you can see the changes in the texture in the "ground" Each "layer" represents a set of years. And as you get further and further into the ground, fossils become older and older.
This is normal polarity case if u look u can clearly see it’s normal
That is called an obtuse angle.
Weather is determined by the values of meteorological factors: temperature, air umididatea, wind direction and speed, atmospheric pressure, air turbulence, the amount and type of precipitation. These factors are measured by specific instruments - thermometers, barometers, hydrometers, weathervane to The measured values over long periods of time (years or decades) statistically give us information about the climate of a region.
