What do the spots represent?
Answer: Spots are actually the bodies way of healing itself. The sebaceous gland is located next to small hair follicles in the skin and secretes an oil known as sebum which is used to prevent the skin and hair from drying out. Spots develop when these pores become clogged and inflamed.

- PURPLE -Denotes revisions that have been made to a map using aerial photos.
What do the dots represent in map of earthquake distribution?
As you have noticed the dots you added fall along or near the lines you drew. These lines represent plate boundaries. At these plate boundaries are faults which are cracks in the earth’s crust where movement has taken place.
What do the spots represent earthquake?
The seismometers are shown as green dots. The calculated distance from each seismometer to the earthquake is shown as a circle. The location where all the circles intersect is the location of the earthquake epicenter.
How are earthquakes distributed on the map?
Earthquakes are distributed along the fault lines which means at the edge of tectonic plates. On a map showing tectonic plates earthquakes will be distributed along the lines on the map. … Earthquakes occur most commonly where the gigantic tectonic plates that form the Earth’s crust meet and rub together.
Where are there no earthquakes?
What do colors on a map represent?
A color can represent a number say a number of people or number of houses creating a visual map of the population or housing density of an area. Colors are also used to show topography with different shades representing distances above or below sea level.

Different colours are used to depict different elevations political divisions roads etc.
What do the dots represent Figure 2?
These dots are arranged to the right and left and above and below the symbol with no more than two dots on a side. (It does not matter what order the positions are used.) Figure 1 shows the Lewis symbols for the elements of the third period of the periodic table. Figure 1.
What did scientists see when all earthquakes are plotted on a world map?
Scientists discovered that when the locations of earthquakes were plotted on a world map these locations occurred in a pattern or variety of patterns. These patterns led scientists to believe that the earth’s crust is divided into different sections or plates.
How are the earthquakes distributed on the map on Figure 5?
The earthquakes are mainly distributed along the edges of the platonic plates on the map. Explanation: … The map also differentiates the different movements of the plates like rubbing against each other or moving apart.
What is the meaning of red dots in earthquake?
The first example shows how the colors change as the shaking at a location progresses from no shaking through weak moderate and strong shaking peaking at a violent shaking level (very dark red) before the shaking dies off (red becomes brighter). …
Why does the earth shake when there is an earthquake?
The tectonic plates are always slowly moving but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction there is an earthquake that releases energy in waves that travel through the earth’s crust and cause the shaking that we feel.
What is earthquake Short answer?
An earthquake is the sudden movement or trembling of the Earth’s tectonic plates that creates the shakes of the ground. This shaking can destroy buildings and break the Earth’s surface. … Seismology studies about the cause repeats type and size of earthquakes. Earthquakes are measured using watching from seismographs.
Are earthquakes scattered evenly or concentrated in zones?
Are earthquakes scattered randomly over the surface of the earth or are they concentrated in definite zones? Earthquakes are scattered around the globe. However they are fixed around certain areas on the edges of faults. These faults can be found on the borders of large stretches of land.
Does the location of earthquakes and volcanoes show a pattern?
How earthquake epicenters around the world is distributed?
Earthquakes are not randomly distributed around the earth rather they are located in distinct zones which can be related to the margins of tectonic plates on the Earth’s surface. Figure 6 shows the distribution of areas of most frequent earthquake activity. The active plate boundaries are superimposed on this map.
Can Singapore be hit by a tsunami?
Singapore is surrounded by water and can therefore be affected by a tsunami. However the megathrust tsunamis like the one that hit the Indian Ocean in 2004 will not affect Singapore: the Indonesian archipelago acts as a barrier that protects the city from such events.
What country has the most earthquakes?
Japan
For which country do we locate the most earthquakes? Japan. The whole country is in a very active seismic area and they have the densest seismic network in the world so they are able to record many earthquakes.
Why Antarctica has no earthquake?
As with the interior area of all tectonic plates earthquakes can and do occur in Antarctica but they are much less frequent than quakes on the plate boundaries. … It is because smaller quakes are much more likely to go undetected in Antarctica because there are very few seismograph stations.
Why are symbols and Colours used on maps?
Topographic maps have unique markings that make them technically useful on the trail. Colors and symbols add the detail unique to a topographic map. … Colors stand out from the map and provide identification to many features such as vegetation and water. Colors represent natural and man-made features of the earth.
How do you color code a map?
- Click the Create Maps from Data tab > Color-Coded Maps.
- In the Color-Coded Maps pane select the variable to map.

Answer: Generally blue is used for showing water bodies brown for mountain yellow for plateau and green is used for plains.
What does the blue colour represent on a map?
The topographical maps use the color blue to show water bodies like perennial rivers canals well tanks and springs. Most contour lines which are relief elevations and features are denoted by the colour brown on a map.
What are the five different elements of a map explain any one?
So the five elements that you should see on any map and be able to identify are the title legend grid directions and scale.
What are the symbols used in maps?
Map symbols are categorized into three categories: Point Symbol Line Symbol and Area Symbol.
What are the conventional symbols?
Conventional symbols are widely accepted signs or sign systems which signify an idea or concept. They represent different features on a map and are not drawn to scale. They are important because: Symbols can be used to depict features like cities roads and railways.
How do scientists know where tectonic plates are?
Modern continents hold clues to their distant past. Evidence from fossils glaciers and complementary coastlines helps reveal how the plates once fit together. Fossils tell us when and where plants and animals once existed. Some life “rode” on diverging plates became isolated and evolved into new species.
