Constructing and Analyzing a Topographic Map In this task, you will create a topographic map based on a clay model. For the model and the topographic map, each contour line will represent an elevation change of 1 inch.

Estimated time to complete: 1 hour

You will need these materials:

lump of modeling clay (approximately 5 to 6 inches in diameter)
string (fishing line or dental floss works best)
ruler
pencil
8.5 x 11-inch piece of paper
After gathering your materials, follow these steps to create your mountain and topographic map.

Part A
Question
Reassemble your mountain by stacking the four pieces in the correct order. In the answer space, sketch a picture of your mountain and its corresponding topographic map. The mountain sketch should be a side view and should include the horizontal dashed lines indicating each section of the mountain that you traced onto your topographic map.

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.

essentially, one bacterial cell splits into two daugurer cells. bacterial offspring don't need or get care from their parents because they are in a sense their own parents. that said, some bacteria can and do depend on other bacteria especially in harsh environments such as bacterial microfilms in hot water tanks.

the circumference of the solar disc is 4375246 km, nearly.
