The idea of continental drift was given by: a) Harry H. Hess b) J. Tuzo Wilson c) Alfred Wegener d) Frederick Vine
Answer (1)
Oceans can be as deep as the Mariana Trench , which is the deepest part of the world's oceans, reaching a depth of about 36,070 feet (10,994 meters).
The crust is the outermost layer of Earth. It is the thinnest layer and is made up of solid rock, being the surface on which we live.
A latitude is the position or coordinate measured along the north pointing axis. Latitude lines run parallel to the equator and help locate a place north or south of the equator.
Minerals are naturally occurring substances made up of one or more elements. They have a definite chemical composition and structure.
One of the most frequently found sedimentary rocks is limestone . Limestone is primarily composed of calcium carbonate, and is commonly found in marine environments.
Sedimentary rocks are formed from the casts or fragments of other broken down rocks. They are created through the processes of weathering, erosion, and sedimentation.
Q#3:
The idea of continental drift was given by: c) Alfred Wegener .
Alfred Wegener was a German meteorologist and geophysicist who proposed the theory of continental drift in 1912. He suggested that the continents were once a single landmass, known as Pangaea, and have drifted apart over millions of years to their current positions. His ideas laid the foundation for the modern theory of plate tectonics.
