Explanation:
Deccan Plateau, a pre-cambrian shield, is partially covered by the Deccan Traps, a large igneous province. The northwestern part of the plateau is made up of lava flows or igneous rocks known as the Deccan Traps. The rocks are spread over the whole of Maharashtra and parts of Gujarat and Madhya Pradesh, thereby making it one of the largest volcanic provinces in the world. It consists of more than 2,000 metres (6,600 ft) of flat-lying basalt lava flows and covers an area of nearly 500,000 square kilometres (190,000 sq mi) in west-central India. Estimates of the original area covered by the lava flows are as high as 1,500,000 square kilometres (580,000 sq mi). The volume of basalt is estimated to be 511,000 cubic km. The thick dark soil (called silt) found here is suitable for cotton cultivation.

Answer:
0.0197 m
Explanation:
Given that,
Last week, a coral reef grew 19.7 mm taller.
We need to find how much it grow in meters.
We know that,
1 mm = 0.001 m
It means,
19.7 mm = (19.7 × 0.001) m
= 0.0197 m
So, it grows 0.0197 m.
