RADAR is used for

  1. locating submerged submarines

  2. receiving a signals in a radio receiver

  3. locating geostationary satellites

  4. detecting and locating the position of objects such as aeroplanes
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Radar is an acronym fro RAdio Detection And Ranging

$\rightarrow$ It is basically a detection system that uses radio waves to determine the range, angle or velocity of objects.
$\rightarrow$ More over; used for distance measurement
$\rightarrow$ Hence; can be used for detecting and locating the position of objects like aero planes

Which satellites help in finding and managing resources?

  1. Navigation satellites

  2. Communication satellites

  3. Remote sensing satellites

  4. Research satellites
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Remote sensing is the science of obtaining information about objects or areas from a distance, typically from aircraft or satellites. Remote sensing has a wide range of applications in many different fields i.e it helps in finding and managing various resources. For eg: Natural resource management: Remote sensing satellites helps to monitor land use, map wetlands, and chart wildlife habitats. Data collected can be used to minimize the damage that urban growth has on the environment and help to decide how to best protect natural resources.

In which type of environmental scanning, ad hoc decisions are made?

  1. Passive Scanning

  2. Active Scanning

  3. Directed Scanning

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Passive scanning helps to take the ad hoc decisions. Ad hoc decisions refer to those decisions which are taken in case of emergencies. Passive scanning is also known as ongoing scanning which takens place unconsciously in the organization.

Multiple choice

Which system gathers, stores, and analyzes geographic information?

  1. GPS

  2. remote sensing

  3. GIS

  4. satellites

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A Geographic Information System (GIS) is a computer system designed to capture, store, manipulate, analyze, manage, and present all types of geographical data. While GPS is used for finding precise locations and satellites collect data, GIS is the comprehensive system that integrates and analyzes this information.

Multiple choice

What is remote sensing?

  1. using software to combine data

  2. analyzing different types of data

  3. tracking changes on Earth's surface

  4. getting information from far away
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Remote sensing is defined as the process of acquiring information about the Earth's surface from a distance, typically using sensors on satellites or aircraft. This allows scientists to gather data without making physical contact with the area being studied. Therefore, getting information from far away is the most accurate description.

Multiple choice

Which of the following helps people get directions while they are driving?

  1. GIS

  2. GPS

  3. remote sensing

  4. satellites
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The Global Positioning System (GPS) is a satellite-based navigation system that provides real-time location and direction tracking, making it the primary tool for driving navigation. GIS is used for analyzing spatial data, and remote sensing is used for gathering data from a distance, neither of which directly provide driving directions.

Multiple choice

What are satellite tags used for in the marine environment?

  1. Determine the location of a surface buoy

  2. Tracking currents

  3. None of the above

  4. Tracking organisms
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Satellite tags are attached to marine animals, such as sharks, turtles, and whales, to track their movements, migration patterns, and behaviors across the ocean. While other instruments track currents or buoys, satellite tags specifically revolutionized our understanding of marine organism migrations.

Multiple choice

GPS has benefited seafaringand oceanography by doing what?

  1. bridging the gap between submersibles and scuba.

  2. making it possible to see underwater.

  3. increasing under water duration.

  4. making navigation significantly more accurate.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The Global Positioning System (GPS) revolutionized marine navigation and oceanography by providing highly accurate, real-time location data anywhere on Earth. This allows research vessels to precisely map the seafloor, track currents, and return to exact sampling locations, which was much more difficult with older navigation methods.

Multiple choice

What collects the data used in Remote asensing

  1. Sonar

  2. Geographers

  3. Cartographers

  4. Satellites
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Remote sensing involves collecting data about the Earth's surface from a distance, typically using sensors mounted on satellites or aircraft.

Multiple choice
