Answer: Usually on a map, solid lines represent boundaries between nations, or if it is a map of the states, it would represent the borders of the states.
Explanation:
Fossils are the remains of plants and animals that have been preserved for millennia in stones under the Earth's surface. They contain the long chapters of the history of our Earth. Fossils tell us what the earth looked like many millions of years ago, what kind of animals and plants lived on its surface and how it was changing. Fossils show us a history of over a billion years old.
From the fossil from a dry, mountainous area we can conclude that the area was once underwater and over time the soil has risen as result of continental drift and uplift. So, a mountain was once the bottom of a prehistoric ocean or sea.
Answer:
Hey!
Stars are formed from massive clouds of dust and gas in space CALLED NEBULAE. Gravity pulls the dust and gas together to form a PROTOSTAR...much like a baby star!
These gases come together, and as they do, the temperature begins to increase...
The finished stars are formed when the OPTIMUM TEMPERATURE is released for the chemical reactions within to start!
OUR SUN'S COLOUR IS WHITE! (Although its actually all the colours mixed together)

Answer:
9.) <em>Humpback Whales</em>
10.) <em>Phytoplankton.</em>
11.) <em>Sotronger upwelling winds</em>
Explanation:
9.) A primary consumer feeds on primary producers, of all the options given Humpback Whales, are the only ones meeting the criteria in the options given since they feed with plankton (a primary producer).
10.) Phytoplankton are the base of the Southern Antarctic Ocean trophic chain. In the nutrient-rich upwelling zone waters, they can reach huge blossoms and are far more common than other forms of zooplankton in this zone.
11.) The productivity of this ecosystem is influenced by the seasonal cycle of the upwelling winds, these peak during the months of December and January, carrying more nutrients and allowing trophic networks to work more efficiently and actively allowing for more productivity.
Answer:
It is formed on earths surface because igneous rock is formed by volcanoes and volcanoes are on land
