Milankovitch cycles is the correct term for changes in the elliptical shape of Earth’s orbit every 100,000 years.
Milankovitch cycles are the various influences of the earth's movements on its climate over thousands of years. There are three dominant Milankovitch cycles which are eccentricity, axial tilt, and precession, that combines to affect the location of solar energy around the earth, seasonality, and eventually influence climatic patterns.
Answer:
Szlak Orlich Gniazd w południowo-zachodniej Polsce to znakowany szlak wzdłuż łańcucha 25 średniowiecznych zamków między Częstochową a Krakowem. Szlak Orlich Gniazd został po raz pierwszy wyznaczony przez Kazimierza Sosnowskiego. Od 1980 r. Znaczna część obszaru została wyznaczona jako obszar chroniony zwany Parkiem Krajobrazowym Orlich Gniazd.

<h3>Mid-ocean ridges and plate tectonic theory</h3>
Explanation:
The German geophysicist, Alfred Wegener, proposed the continental drift theory which explained about the drifting of continents from a single large mass.
With the advent of sonar-equipped ships, scientists were able to map the ocean floor. They collected topographic data from the ocean bed which showed them varied features like valleys, high mountains, flat plains etc.
Later, they discovered a ridge in the mid-Atlantic Ocean which ran parallel to the continental coastline and up above 1-2 km above the ocean floor. Then similar mid-ocean ridges were found in other major oceans like the Pacific and the Indian Ocean which also ran parallel to the continental coastline.
These ridges corresponded to hot magma regions which drifted the ocean floor corresponding with Wegner’s continental drift theory.
Later with the discovery of magnetometers and its usage in ships, scientists were able to detect the magnetism exhibited rocks on the sea floor.
Combining all the theories, the continental drift theory, ridges of mid-Atlantic Ocean, magnetism of rocks at ocean bed all led to the formulation of the plate tectonic theory.
