If you look on openstudy.com they have lots of answers to this :-)
Answer:
Maps and globes are drawn to scale and use symbols to represent topography and other features on Earth's surface. Grid lines on maps and globes are often used, with lines curving because the Earth is a sphere. The baselines for measuring distance on Earth are the equator and the Prime Meridian. Satellites are also often used as a mean to graph.
Answer:
d). It is easier to make a large reflecting telescope than a large refracting telescope.
f). A reflector can collect more light than a refractor.
Explanation:
A telescope is a device that is used to observe distant objects by the use of lenses and mirrors. It is also used to observe different distant objects by their reflection, absorption, emission or the reflection of the electromagnetic radiations.
Most of the professional telescopes are reflectors because :
1. The reflected telescope is able to receive more of the light when it reflects all the light falling on surface. And it is easier for making a large telescope rather then making large lenses for the refracting telescope. So it is easier to make large reflecting telescope than a large refracting telescope.
2. A reflected telescope receives all the wavelength of the light and it reflects all the light falling on the surfaces where it is refracted telescope that contains lenses cannot absorbs all the light and causes the chromatic aberration.
<span>By the given data the following conclusion is best supported: The oceanographer is is traveling toward a mid ocean ridge.
At the mid-ocean ridge network crust is created. So as the oceanographer moves toward it, it becomes progressively younger.
