Which map scale would show the greatest amount of physical details?

Large scale maps generally show more detail than small scale maps because at a large scale there is more space on the map in which to show features. Large scale maps are typically used to show site plans, local areas, neighborhoods, towns etc. 1:2,500 is an example of a large scale.

Which remote sensing systems sense the longest wavelengths?

7 µm – 3.0 µm) is used for remote sensing. Thermal IR (3 µm – 35 µm) is the radiation emitted from earth’s surface in the form of heat and used for remote sensing. This is the longest wavelength used in remote sensing. The shortest wavelengths in this range have properties similar to thermal infrared region.

What information does a globe most accurately depict?

A globe is a scale model of the Earth. Because Earth is round, a globe presents the most accurate depiction of geographic information such as area, distance, and direction.

Which of the following forms of remote sensing is based on SOund?

This method of remote sensing is called sonar (SOund NAvigation Ranging). Another method of remote sensing is called radar (RAdio Detection And Ranging). Radar is based on a different kind of wave. These waves are electromagnetic.

What is one advantage of maps over aerial photographs?

Q. What is one advantage of maps over aerial photographs as a way of understanding Earth’s surface? Photographs do not give an accurate picture of the region they show. Which information does a physical map always show?

How does a scale shown on a map help us?

It helps in measuring the distance. The connection between this present reality size of a geographic element and its agent highlight on a map is known as scale. Scale is regularly addressed as a proportion between this present reality size and the size in units on the map.

When air is heated does it expand and lower pressure?

Air mass – huge volume of air that is relatively uniform in temperature and water vapor. 2. But atmosphere has no walls, so heated air expands, becomes less dense. Thus, net result is that pressure actually decreases when heated.

On which one of the following projections do great circle routes appear as straight lines?

A gnomonic map projection is a map projection which displays all great circles as straight lines, resulting in any straight line segment on a gnomonic map showing a geodesic, the shortest route between the segment’s two endpoints.

Which of the following is not a map essential?

Option (C) Volume is the correct option. Maps being a two-dimensional tool does not have the possibility of computing volumes. Volumes of maps are unnecessary and are not part of the features of maps hence this is the correct answer since it is not needed in maps.

Why maps are usually preferred over globes in geography since it is a more accurate representation of the earth than a map?

Because world maps are drawn on a flat surface, they cannot show Earth’s curved surface without significant distortions. Globes help to counter that problem. A globe is a spherical representation of a planet’s surface or another large area.

Which part of the earth is best reflected on a map?

When the cylinder is cut open and flattened into a map, the regions near the Equator are the most accurate. Regions near the poles are the most distorted.

Why is a map not a true representation of the earth?

Answer: Maps are less accurate than globe because map is a flat presentation of our earth but globe is the spherical presentation of the earth and globe are more accurate than maps because globe is a model of earth and we can imagine how our earth looks like by the globe.

What is radar remote sensing?

A satellite-based synthetic aperture radar (Synthetic Aperture Radar, SAR) scans the earth’s surface by means of microwave radiation. The SAR antenna transmits microwave pulses and receives the backscattered echo from the surface.

Can sonar used in space?

sonar will not work in space because there is no transmissive medium out there to carry sound waves. Radar works fine in space and has been used to study the surfaces of distant planets.

Why is remote sensing technology necessary for studying features on Earth’s surface?

Geographers use the remote sensing as a tool to monitor or measure the phenomena on earth’s lithosphere, hydrosphere, atmosphere and biosphere. The sensors record information about an object by measuring the electromagnetic energy that is reflected back and radiated from the object on the earth surface.

What type of information does a physical map always show?

A physical map shows the physical features of an area. It also provides readers with information about the topography, or the height, depth, and shape, of these features. Physical maps identify mountains, deserts, bodies of water, and other landforms.

What type of information does a physical map show?

A physical map is one that documents landscape features of a place. These maps generally show things like mountains, rivers, and lakes. Bodies of water are commonly shown in blue. Mountains and elevation changes are sometimes shown with different colors and shades to show elevation.

Why the scale of a map changes with the size of the area represented?

How Scale Affects Feature Representation. The larger the scale of the map, the better the features that can be detailed. A map that shows the water network of a small area may show the river as a polygon layer and will show the tributaries of that river.

What is the purpose of the scale?

Map scale is a mathematical method for expressing how map distance compares to ground distance, the distance on the surface of the earth. Because a map’s scale determines how features are represented on the map, it also affects the overall interpretation of the map.

Why does air pressure in the atmosphere change as altitude changes?

As altitude increases, the amount of gas molecules in the air decreases—the air becomes less dense than air nearer to sea level. This is what meteorologists and mountaineers mean by “thin air.” Thin air exerts less pressure than air at a lower altitude.

Does rising air affect the movement of air from its surrounding?

A few basic principles go a long way toward explaining how and why air moves: Warm air rising creates a low pressure zone at the ground. Air from the surrounding area is sucked into the space left by the rising air. Air flows horizontally at top of the troposphere; horizontal flow is called advection.

What happens to air pressure as you change altitude?

Air pressure is higher at lower altitudes. Air density is higher at lower altitudes. There is more space between air molecules at higher altitudes. There is less oxygen to breathe at the top of a high mountain than there is at sea level.
