Define coastal zone and its characteristics. Also make a map highlighting the coastal lines of India.

Coastal zone is the area where land meets the sea, it's a dynamic and constantly changing environment. It typically includes a range of habitats, such as beaches, dunes, cliffs, estuaries, and wetlands. The characteristics of coastal zones vary depending on the specific location, but some common features include:High biological productivity due to the mixing of nutrient-rich water from the ocean and freshwater from rivers.
High levels of biodiversity, with many unique species adapted to the coastal environment.
High levels of human activity, including residential and commercial development, fishing, and tourism.
Vulnerability to natural disasters, such as hurricanes, storm surges, and tsunamis.
India has a long coastline of approximately 7,517 km, which runs along the Bay of Bengal in the east, the Arabian Sea in the west, and the Indian Ocean in the south. The coastal zone of India is a unique and diverse environment that supports a variety of ecosystems and habitats, including beaches, mangrove forests, coral reefs, estuaries, and wetlands. The following are some of the characteristics of the coastal zone in India:

High biodiversity: The coastal zone of India is home to a wide variety of plant and animal species, many of which are endemic to the region. The mangrove forests of the Sundarbans, for example, are home to the Royal Bengal Tiger, while the coral reefs of the Andaman and Nicobar Islands support a diverse array of marine life.

High levels of human activity: The coastal zone of India is densely populated and supports a variety of economic activities, including fishing, aquaculture, tourism, and port development. This has led to significant environmental degradation, including pollution, habitat loss, and overexploitation of natural resources.

Vulnerability to natural disasters: The coastal zone of India is highly vulnerable to natural disasters, including cyclones, storm surges, and sea-level rise. In recent years, severe weather events such as the 2004 Indian Ocean tsunami, the 2017 Cyclone Ockhi, and the 2019 Cyclone Fani have caused significant damage and loss of life along the Indian coast.

Coastal erosion: The coastal zone of India is experiencing significant coastal erosion, particularly in areas of high wave energy and human activity. This is leading to the loss of beaches, dunes, and other important habitats, and is exacerbating the impacts of climate change on the region.

In conclusion, the coastal zone of India is a unique and diverse environment that supports a wide variety of ecosystems and habitats, but is also facing significant environmental challenges. It is important to implement sustainable coastal management practices that balance economic development with environmental conservation and protection of vulnerable coastal communities.
