What is the main reason Australia and New Zealand have such unique biodiversity? A. Both nations have laws that protect endangered species. B. They are islands, so the species there evolved in isolation. C. They have climate patterns that are unlike other places on Earth. D. Both nations are sparsely populated, so there is more native habitat.

55% is the correct answer.

Answer:I know some of you might be confused by the answer below

so this is a better one Higher latitudes, which are closer to the poles, are colder than lower latitudes. Cold ocean water flows from higher to lower latitudes , as cold water moves in to replace rising warm water closer to the equator. The shapes of the continents also determine the actual paths of the currents.

Explanation:

Answer:

D. Antarctica.

Explanation:

After the summer solstice i.e. 21st June the Sun starts to move towards Southern hemisphere due to revolution of Earth around the Sun on it's orbit and by the time it reaches up to Tropic of Capricorn in Southern hemisphere winter solstice arrives i.e. 22nd December and for next few months this part of Earth receives ample amount of Sunlight whereas, Northern hemisphere of Earth experiences winter season.

In January Antarctica receives height of it's summer with average temperature reaching up to 0.3-0.4 degree centigrade and hence provide suitable condition to conduct studies and experiments.

Answer:

Latitude and Longitude have been used as a grid measurement system for navigating the earth for hundreds of years.

Explanation:

    One of the main and best known terrestrial location systems is the geographic coordinate system, which arises from the combination of latitudes and longitudes. Thus, these two elements together indicate the exact reference of any point on our planet's surface relative to its whole, allowing both absolute location and relative distance between two locations.

    Latitude is the distance, in degrees, from any point on the earth's surface to the Equator Line, the main land parallels. The parallels, in turn, are the imaginary lines drawn horizontally to the earth's main axis, east-west or west-east.

    Thus, the Equator Line, which is in the exact position of equal distance to the two terrestrial poles, has a latitude of 0º, increasing north to 90º and decreasing south to –90º.

    Longitude, in turn, is the distance in degrees from any point on the earth's surface to the Greenwich Meridian, an imaginary line that, by convention, separates the western and eastern hemispheres. Meridians are lines drawn vertically north-south or south-north.
