Answer:
Continental drift in terms of plate tectonics.
Explanation:
- Continental drift is a theory given to explain the formation of various plates or slabs on the surface of the earth and the theory is evident in the form of Alfred Wegener as a geologist who through his research and discoveries and advanced knowledge gave the concept.
- Plates on which the landmasses and various features are made is not static as it looks and is more dynamic and was more destructive in the past as the formation of the earth during the 4.6 billion years ago the continental landmass underwent transformations and breakthrough happened as the split and rejoined and again joined to form what is seen today.
- These plates drifted in such ways that the landmasses formed various properties of the northern and southern hemispheres. Wegener gave evidence of Jigsaw fit puzzle, drifting of the climatic zones, spreading of the plants and animals located at the same continental borders.
- Moving of the plates under the action of gravity and wind speeds.
Hydrogen, helium, and nuclear fusion
Answer:
Hydrogen in the core of the star is converted to helium by nuclear fusion. When the hydrogen supply in the core begins to run out, and the star is no longer generating heat by fusion, the core becomes unstable and contracts.
Cosmology is the study of the universe, including its origin, nature, and evolution.
Geology is the study of rocks found on earth and the changes it underwent as a result to the changes that occurred on earth.
Meteorology is the study of the atmosphere. It is an interdisciplinary scientific study.
Answer:
All three statements are sometimes true and sometimes false
Explanation:
The Moon orbits the Earth, with the same face always toward the Earth.
1. The moon is sometimes between the Sun and the Earth. At other times, it isn't.
2. The Sun shines on the back side of the Moon, but it also shines on the front side.
3. The side that faces the Earth is sometimes dark (New moon) and sometimes lit (Full moon).
