In other words, climate means the condition of the temperature, rainfall, wind, humidity, atmospheric pressure and other meteorological elements in any area of earths surface for a very long period of time.
In other words, Climate just means the usual condition of the temperature, rainfall, wind, humidity, atmospheric pressure and other meteorological elements in any area of the Earth's surface for a long period of time.
Two examples of different global climates throughout the Earth's history is in the polar area. Which is in Antartica usually the polar area is cold and dry throughout the years. While arid zones are usually very hot and dry all year, including the deserts of North Africa.
Geologists tend to look for clues in the Earth's natural environmental records. They gather clues about the past climate that are actually deeply buried at the bottom of the ocean that are absolutely locked away in our beautiful coral reefs. Animals in specific climates also tend to help unlock certain information of past climate change.
So what is a Milankovitch cycle? Basically it is described as an effect of changes in the Earth's movements. So what are the 3 cycles of Milankovitch? Eccentricity plays a big part, it describes in other words the degree variation of the Earth's orbit around the sun. Then we have obliquity and percussion.
Volcanic Activity can range from either the leak of gas, the release of lava(that doesn't explode), or even the explosive kind that causes extreme bursts. While not only being an extreme burst it is also very lasting. As for the volcanic event, it is triggered by a continuous source, this can be an earthquake, gas emissions on the surface or when steam interacts with magma at the surface. With all this it causes the volcano to erupt as it gives it energy to do so.
What exactly makes an ocean current? So tides very much contribute to coastal currents that happens to travel very short distances. As we know it a major surface ocean current are out in the open, but there caused by wind which drags itself towards the surface of the water. Then that's when the water and the wind combine forces and go towards the same direction.
