The answer is; D

As the sunlight changes media from the atmosphere into the water, some of it is reflected back while the rest is refracted and diffused by the water. The deeper the water column the higher the diffusion. Therefore, leaves under water receive lower sunlight intensity hence slowing down the rate of photosynthesis.

Alexus [3.1K]

A topographic map represents earth's surface features like land forms and structures, rivers and lakes, mountains and hills, elevations and other natural features along with man-made artificial features like cities, buildings, monuments, roads, bridges etc. These are formed by contour lines.

Topographic maps are printed with revision dates to observe the changes happening on the Earth's surface. Various land forms keeps changing due to natural and man-made causes and these needs to be updated accordingly to provide accurate details.

A satellite image provides details of the earth aerially from space. These provides details of a land form or any earth structure currently.

By comparing with older satellite images or topographic maps with the current one, the changes which occurred over time can be observed.
