Sonar Raders were used to discover "underwater mountain ranges"
Some scientists observe the natural world by doing experiments outside or in a plant or animalâ??s natural habitat. Other scientists may study cells of organisms under microscopes to find out more about them.

Sedimentary Rocks in Layers

No animals lived in underwater Ohio since it was underwater. They had to be fish, but no mammals.
Zoologists are like scientists but who study animals. They observe animals both in their natural habitats and in the laboratory in order to learn as much as possible about animal life.
Scientists do not observe Mercury as often because it is difficult to do so.
It is not impossible to study plants and animals that are still alive. Scientists frequently observe plants and animals and even run tests and experiments on them in order to learn more about them.
it depends on the size of the To_observe_a_small_living_organism_a_scientist_might_use_a. If it is microscopic, then scientists might have to observe it using it using a microscope. If it can actually be seen, then scientists mught actually take a sample of it back to the labratory to observe physically
Tools enable scientists to make more accurate observations, and to observe things that they otherwise could not observe. For example, microscopes allow scientists to observe bacteria, which otherwise are too small to see.
There are thousands of species of cold-blooded animals, including reptiles such as snakes, lizards, and turtles, as well as amphibians like frogs and salamanders, and fish. Cold-blooded animals rely on their environment to regulate their body temperature, as opposed to warm-blooded animals that can internally regulate their temperature.
Scientists observe pretty much everything. Clues can be anywhere.

The instrument scientists use to observe the planets is a high powered telescope.
