Main Difference
The key difference between Physical Map and Political Map is that Physical Map indicates the natural features of a place like mountains, waterbodies plains, etc. and The political map shows territorial features like country, cities, nations and their boundaries.
Physical Map vs. Political Map
The difference between a political map and physical map stems from the purpose for which they are created. Before discussing that further, let us first see what a map is. Maps are representations of natural features and landforms on a piece of paper with greatly downscaled ratios. Maps are important as they could be used to locate a place in an unknown area and also used to get directions to reach a particular location. To meet the requirements, different types of maps are available out there. Two important types of maps are the political map and physical map. A physical map is used to show geographic properties of an area such as mountains and rivers, while a political map is one that shows the cities, roads, and borders of different countries. This is the key difference between a political map and physical map, but there are other differences that we will discuss in this article.

Answer:
A stalactite
Explanation:
It is produced by precipitation of minerals
That's called a "geostationary" orbit. (Not "geosynchronous".)
It's the situation when the satellite's orbit is
-- perfectly circular,
-- exactly over the equator,
-- and at exactly the right distance from the center of the Earth
(<span>42,164 km or 26,199 mi).</span>
None of these conditions can ever be perfect, and in fact they change over time.
So every real geostationary satellite actually describes a little figure-8 in the sky
once a day. The better its orbit is, the smaller the figure-8.
In order to keep the orbit reasonably correct, it needs a puff from its onboard
thrusters every once in a while.
That's how a TV or weather satellite reaches its "end of life", if it doesn't get
smashed by a meteoroid first: Either its solar panels get too dusty and chipped
by micrometeoroids to generate enough power, or else it runs so low on fuel for
its onboard thrusters that it can't be kept in a useful orbit. At that point, the fuel
that remains is used to intentionally put it into a crazy orbit, where it will dip low
into the atmosphere and burn up.
Why destroy it ? To get it out of the geostationary orbital track, and open up one
of those precious slots for a new, young satellite to take its place. There are only
a few hundred slots available where a satellite can be geostationary. (And a slot
over the Indian Ocean doesn't do TV viewers in the US much good.)
Since, AD ≅ BC, ∠BCD ≅ ∠ADC and segment CD ≅ DC, △ADC ≅ △BCD by SAS. Therefore, based on CPCTC, DE ≅ CE.
Explanation:
- We are given AD ≅ BC and ∠BCD ≅ ∠ADC.
- The segment CD is common for △ADC and △BCD.
- This means BCD and ADC are isosceles triangles.
- Therefore, we can say that △ADC ≅ △BCD by SAS.
- Because of CPCTC, segment DE is congruent to segment CE.
- Hence, based on the isosceles triangle theorem, DE ≅ CE.
