Answer:
There are dried-up riverbeds on Mars.
Explanation:
Now there is some evidence that is known that in Mars there is some water in layers below the soil, that mean that there are some possible storage of water. The life in Earth as we know it, it is possible just with the presence of water, that is the reason of this important knowledge.
In Mars atmosphere is almost carbon dioxide (aprox. 95 %) and just some traces of water, so the main source is located in soil.
The English Channel is the body of water between England (Great Britain) and France, it is connected to the Atlantic Ocean.
Being a body of water, it can't be a water way - so the answer b) is false.
In fact, from the description above you know that the answer a. an extension of the Atlantic Ocean between England and France is true.
The Earth's rocky outer crust solidified billions of
years ago, soon after the Earth formed. This crust is not a solid
shell; it is broken up into huge, thick plates that drift atop the soft,
underlying mantle.
The plates are made of rock and drift all over the globe; they move both
horizontally (sideways) and vertically (up and down). Over long
periods of time, the plates also change in size as their margins are
added to, crushed together, or pushed back into the Earth's mantle. These plates are from 50 to 250 miles (80 to 400 km) thick.
Answer:
The correct answer is D. National Parks are an invention of the United States that has spread around much of the world, as a way of protecting some of the finest parts of the world.
Explanation:
A national park is a park in which the protection of nature comes first, albeit almost always in alignment with human activities (in particular recreation, often also forestry, agriculture, hunting and fishing, sometimes mining) in and around the national park. The state usually recognizes the national significance of such a park and guarantees its protection. The term was coined in the US around 1870. Shortly thereafter the Yellowstone National Park was founded in a special area with geysers and bison among others. This park serves as an example for many other parks. Since then, hundreds of national parks have been established worldwide.
