How did ancient Greece make their maps?
They drew them!
How did Columbus extend cartography?
Columbus extended cartography by making new maps of the new world. Columbus didn't make the maps he had someone else make them.
Did the pilgrims have a map?
Of Europe. Not America. Natives did not make the kind of maps we use.
Why did george Vancouver decide to go on his journey?
to make maps and meet people at Nootka
What did the 19th century explorers do in Hawaii?

How do scientists map features of the ocean floor using sonar?
Scientists use sonar to map the ocean floor by sending sound waves from a ship to the ocean floor. These sound waves bounce back and are picked up by a receiver on the ship, providing information about the depth and texture of the ocean floor. By analyzing the time it takes for the sound waves to return, scientists can create detailed maps of the underwater terrain.
Which method is not a technique currently used by ocean scientists to map the topography of the ocean floor?
Satellite imagery is not typically used by ocean scientists to map the topography of the ocean floor, as it cannot penetrate the water to provide detailed depth information. Instead, methods such as multibeam sonar and lidar are commonly used to create detailed maps of the ocean floor.
How can scientists map the ocean floor using the satellite Geosat?
Scientists can map the ocean floor using the satellite Geosat by measuring the height of the ocean surface, which is affected by the gravitational pull of underwater features. By comparing these measurements with known gravitational models, scientists can infer the shape and depth of the ocean floor. This method, called satellite altimetry, allows for the creation of detailed maps of the seafloor topography.
What does Landsat help scientists to make accurate maps of?
Landsat helps scientists to make accurate maps of land cover, land use, changes in the Earth's surface over time, deforestation, urban development, and agriculture. These maps are crucial for monitoring environmental changes, managing natural resources, and understanding the impacts of human activities on the environment.
Are submersibles used to map the ocean floor?
no sonars areNo they are not, a sonar maps the ocean floor.
What technology did Harry Hess use to map the ocean floor?
Harry Hess used echo sounding technology to map the ocean floor. This technology involved sending sound waves from a ship and measuring the time it took for the sound waves to bounce back, allowing scientists to determine the depth of the ocean floor and create detailed maps.
What does an oceanographists do daily?

What are the lines in the ocean on Google Maps and what do they represent?
The lines in the ocean on Google Maps are called bathymetric lines. These lines represent the depth of the ocean at different points. They help users understand the underwater topography and features of the ocean floor.
How is sonar utilized to map the ocean floor effectively and accurately?
Sonar is used to map the ocean floor by sending sound waves from a ship or underwater vehicle. These sound waves bounce off the ocean floor and return to the device, allowing scientists to create detailed maps based on the time it takes for the sound waves to return. This method is effective and accurate because sonar can penetrate deep into the ocean and provide precise measurements of the seafloor's depth and features.
What was used aboard HMS Challenger to map the ocean floor?
HMS Challenger used echo soundings, which involved sending sound waves to the ocean floor and recording the time it took for them to bounce back, to map the ocean floor. This method helped create the first global maps of ocean depths.
Why is it important to have maps on the ocean floor?
because you know whats happening and remember what is marked so other people can know what it is
What are scientists who make maps of the earths surface called?
Scientists who make maps of the Earth's surface are called cartographers. They analyze geographic data and use specialized software to create accurate representations of different locations on Earth. Their maps are used for various purposes, including navigation, urban planning, and resource management.
