Small scale manufacturing industries in cottage industries play a very important role in the economic development of India if any amount of capital is invested in small scale industries it will help in reducing unemployment in India and increasing self employment
All aspects of human activity, from agriculture to urbanization, are changing that influence human settlement and economic development.
<h3>How economic development
affects the environment?</h3>
Natural resources are the basic requirement for the production of the many materials that are used by humanity on a daily basis.
While using the products results in pressure and pollution on the environment and other species of the environment, so it harms the environment.
Thus, human activity, from agriculture to urbanization affects environment.

Anorthosites, almost entirely made of plagioclase feldspar, are the Moon's earliest rocks. They appear to have developed when feldspar crystallised and floated to the top of the Moon's early magma ocean.
Anorthosite is an intrusive igneous rock made primarily of calcium-rich plagioclase feldspar. All anorthosites found on Earth are coarse crystals, but some Moon samples are finely crystalline. It is almost entirely composed of plagioclase feldspar, a standard, light-weight, light-coloured mineral on Earth. It is an igneous rock that cools and solidifies from hot melting material. This mineral floated to the surface and created anorthosite. Anorthosite is a significant rock type on the Moon's surface, accounting for most of the highlands and crust. This sample, recovered by Apollo 16 astronauts, has been proven to be 4.19 billion years old.

Answer:
Options (A), (C), (D) and (E)
Explanation:
The tectonic setting usually refers to the plate tectonic activity, where the earth's crust is divided into numerous small and large plates that move over the layer of the asthenosphere. This motion of plates gave rise to the formation of different geological settings on and under the earth's surface.
Some of the common tectonic activities that are associated with the volcanic activity are as follows-
- Continental rift refers to the splitting of the continental areas, where the rift valley is formed eventually and due to this divergent motion of the crust, there form volcanoes in the adjacent side of the plate boundary.
- Mantle plumes refer to the region where the hot and less dense magma rises up from the interior of the earth, forming large convection cells in columns. When plates move over this region, there form volcanoes. For example, Hawaii.
- Island arcs and continental arcs are commonly formed in the convergent plate boundaries, where the subduction zone is formed and as the magma rises upwards towards the surface in the over-riding plate, it forms volcanoes.
Thus, the correct answers are options (A), (C), (D) and (E).
