How does the Earth create a magnetic field?
The Earth’s magnetic field is created by the rotation of the Earth and Earth's core. It shields the Earth against harmful particles in space. The field is unstable and has changed often in the history of the Earth.
Answer:
Caves, caverns, sinkholes, funnel-shaped holes, underground rivers and lakes
Explanation:
The karst topography is found at places that are dominated by rocks made out of calcium carbonate, better known as limestone. These rocks react with the water very easily and get dissolved from it very easily. Because of the large scale dissolving, this type of topography has numerous specific features. Some of the most common features in the karst topography are the caves, sinkholes, caverns, funnel-shaped holes, underground rivers, underground lakes etc. All of them are very attractive and understandably cause a lot of interest, thus they are often tourist destinations, but more importantly of big scientific interest. The biggest problem with this topography is that it is generally not stable, and it is very common that the rocks can crumble, which makes them relatively dangerous if visited at certain periods of the year, especially when there is more precipitation.
Answer:
•The existence of water at the Earth’s surface—neither too much nor too little—that is in liquid form.
•Proximity to the sun—neither too much heat nor too little.
•System of plate tectonics that enables the carbon-silicate cycle regulating temperature.
•The right size—large enough to hang on to its atmosphere, but not so large to hold on to too much atmosphere and consequently too much heat.
•Its protection by “big brother Jupiter,” whose gravity helps divert and vacuum up incoming debris and keep Earth safe.
•The moon’s stabilizing effect on our planetary rotation, which prevents the poles from shifting unexpectedly.
