Explanation:

When a destructive wave hits a coastline, it causes the washing away of the coastline and erosion of the beach fronts.

When a constructive wave hits a coastline, new sediments are deposited there.

Coastline is an area along the shore that straddles between the continent and the ocean.

A destructive wave is a very high energy wave that moves materials from the coast in to the ocean. They cause the washing away of the ocean fronts.

A constructive wave are usually of low energy. They bring materials landward more than towards the ocean.

What are the effect of topography

andriy [413]

Answer:

They can help to establish conservation areas such as watersheds and wind blocks.

The topography of the land can have an impact on weather patterns. Meteorologists use information on mountains, valleys, oceans, and lakes to help predict the weather.

Answer:

1) a) $r_{R,I} = 1150\,m$ , b) $r_{R,II} = 3400\,m$ , c) $r_{R,III} = 2750\,m$ .

2) a) $r_{R,I} = 45,2\,km$ , b) $r_{R, II} = 28,15\,km$ , c) $r_{R,III} = 51,8\,km$ .

Explanation:

The scale factor is defined by the following expression:

$n = \frac{r_{S}}{r_{R}}$ (1)

Where:

$n$ - Scale factor.

$r_{S}$ - Scale distance, in centimetres.

$r_{R}$ - Real distance, in centimetres.

1) If we know that $n = \frac{1}{50000}$ , $r_{S,I} = 2,3\,cm$ , $r_{S,II} = 6,8\,cm$ and $r_{S,III} = 5,5\,cm$ , then the actual distances in metres are:

$r_{R,I} = \frac{r_{S,I}}{n}$

$r_{R,I} = \frac{2,3\,cm}{\frac{1}{50000} }$

$r_{R,I} = 115000\,cm$

$r_{R,I} = 1150\,m$

$r_{R,II} = \frac{r_{S,II}}{n}$

$r_{R,II} = \frac{6,8\,cm}{\frac{1}{50000} }$

$r_{R,II} = 340000\,cm$

$r_{R,II} = 3400\,m$

$r_{R, III} = \frac{r_{S, III}}{n}$

$r_{R,III} = \frac{5,5\,cm}{\frac{1}{50000} }$

$r_{R,III} = 275000\,cm$

$r_{R,III} = 2750\,m$

2) If we know that $n = \frac{1}{50000}$ , $r_{S, I} = 90,4\,cm$ , $r_{S, II} = 56,3\,cm$ and $r_{S,III} = 103,6\,cm$ , then the actual distance in kilometres is:

$r_{R,I} = \frac{r_{S,I}}{n}$

$r_{R,I} = \frac{90,4\,cm}{\frac{1}{50000} }$

$r_{R,I} = 4520000\,cm$

$r_{R,I} = 45,2\,km$

$r_{R,II} = \frac{r_{S,II}}{n}$

$r_{R,II} = \frac{56,3\,cm}{\frac{1}{50000} }$

$r_{R,II} = 2815000\,cm$

$r_{R, II} = 28,15\,km$

$r_{R, III} = \frac{r_{S, III}}{n}$

$r_{R,III} = \frac{103,6\,cm}{\frac{1}{50000} }$

$r_{R,III} = 5180000\,cm$

$r_{R,III} = 51,8\,km$
