Answer:

Newfoundland

Explanation:

Let's take a look at both locations and find their eastern-most point.

Newfoundland:

we'll take the capital (St. John's) in reference because it's pretty much the eastern-most point.

Latitude: 47.4815685

Longitude: -53.1085765

Now, let's look at Puerto Rico:

we'll take the Punta del Este, on the island Culebrita:

Latitude: 18.312056

Longitude: -65.220939

To see which is the farther East (we'll assume from continental USA), we need to look at the longitudes, which are the vertical lines on the globe.

Since Newfoundland is at -53 degrees, and Puerto Rico is at -65 degrees, Newfoundland is closer to the Longitude 0 (Greenwich), so it's the one farther East from the continental USA.

Newfoundland is farther east than Puerto Rico since its easternmost point has a lower longitude value (approximately 52.6 degrees West) compared to Puerto Rico's easternmost point (approximately 65.3 degrees West).

The question at hand is about the geographical position of Newfoundland and Puerto Rico in relation to longitude, particularly which location is farther east. Newfoundland, located in Canada, is part of the easternmost province of Newfoundland and Labrador. Its most easterly point is Cape Spear, which has a longitude of about 52.6 degrees west. On the other hand, Puerto Rico is a Caribbean island with its easternmost point, Punta Mulas, near a longitude of 65.3 degrees west. Since lower longitudinal values are farther east, Newfoundland is indeed farther east than Puerto Rico.

Answer:

the center of the earth, the north and south poles, the equator and the Prime Meridian.

Explanation:

To obtain a precise latitude, map makers use 4 universal well-known points of reference that make unanimity among the science community, to ensure consensus.

Those reference points are:

1.) the center of the earth: that is used to calculate the radius of the circles and the various angles to draw the latitude lines.

2). the north and south poles: since the latitude lines have to reach them, starting from the Equator.

3.) the equator: that's latitude 0, so it's a pretty important reference point.

4.) the Prime Meridian, as a perpendicular line for the latitude "rings" and other calculations.

And the same reference points are also used to calculate the longitudes as well.

Final answer:

To calculate latitude, four reference points are used: the equator, prime meridian, North Star (Polaris) for celestial navigation in the Northern Hemisphere, and the observer's horizon. Tools to measure these have evolved from astrolabes to sextants and GPS technology.

Explanation:

The question asks about the four reference points needed to calculate latitude, which involves understanding Earth's geometrical and astronomical features. The reference points necessary to determine one's latitude on Earth include:

The equator, which serves as the starting point for measuring latitude degrees north or south.

The prime meridian, which aids in the orientation of the global coordinate system.

The location of the North Star (Polaris) in the Northern Hemisphere for celestial navigation.

The observer's horizon, as the angle of Polaris above the horizon directly corresponds to the observer's latitude.

Techniques used to measure these points have evolved from simple tools like the astrolabe to advanced instruments like the sextant and GPS technology, which calculates a position in three dimensions using at least four satellites and principles of geometry.

We have several layers of crust but they separated because of the desity level differences. The lighter material cruet layers rose upwards and the heavier materials caused them to drop further down

Answer:

- shows isobars

- was probably used by meteorologists

Explanation:

The map that is presented is a map that was most probably made and used by meteorologists. It is a map that that shows isobars, thus it is a map that represents the air pressures across the US and Canada. We can see the air pressure zones, some of which high, some of which low. These maps are often used when the weather information is concluded about certain areas, as the air pressure is directly connected with the temperature, and the movement of the air masses.

Answer:

shows isobars

Answer:

Mercator projection

Explanation:

Using a flat paper map to represent the sphere that  is our planet has always been a challenge.  The Mercator projection is one of the most common representation, although we know it is more accurate around the Equator line and the precision diminishes as you get closer to the poles.

There are other types of projections, correcting some issues, but with their own flaws too.  The only accurate representation of the planet is a globe, since it matches the shape of the planet.

I'm pretty sure one of the answers is Mercator projection.

Lake Titicaca is the highest navigable lake in the world, with an estimated age of 3 million years, located in the Andean high plateau in the central Andes (within the Collao plateau) at an average altitude of 3812 meters above sea level.

This lake is located between the territories of Peru and Bolivia, where 56% of its extension belongs to Peru and 44% to Bolivia, serving as a border between both territories. In addition, it has an average depth of 107 meters and is the largest body of freshwater in South America.
