This is called Marble. It was once limestone, but heat and pressure changed it, recrystallizing the calcite and distorting the layers. What kind of rock is it?.
-
Igneous
No. Igneous rocks formed from magma or lava. This is not an igneous rock. -
Sedimentary
No. Sedimentary rocks are deposited by wind, water, ice, or gravity, and they often contain fossils. When it was limestone it was a sedimentary rock, but not now. -
Metamorphic
Yes!. This marble been changed by heat and pressure from a different kind of rock. It is metamorphic. -
Marble is not a rock.
No. Marble is a naturally occurring solid that forms large layers in the Earth. Marble is a rock.

This magnet attracts the compass and the magnetized needle without having to come in contact with them. This is an example of a force acting at a distance.
Which of the following is another example of a force that acts at a distance without actual contact?
-
Wind turning a windmill.
No. The moving air is pushing against the blades of the windmill. Because a physical object (moving air) is pushing on the windmill, this is a contact force. -
Sound causing you to hear something.
No. For you to hear a sound, the vibrations of the object make the air vibrate. That is a contact force because there is direct contact between the vibrating object and the air. The vibrating air is in contact with your ear drum, causing it to vibrate too. That lets you hear the sound. Because a physical object (vibrating air) is moving your ear drum, this is a contact force. -
Gravity causing a rock to fall.
Yes. The gravitational attraction between the Earth and the rock does not need physical contact. The rock would fall, even if it was in a total vacuum, with no physical object to push or pull on it. This is a force acting at a distance. -
Throwing a ball to knock over a target
No. To throw the ball, your arm pushes against it. Your arm moving the ball is a contact force. The moving ball hits the target to knock it over. The ball is touching the target to knock it over, so this is also a contact force.

The Common Raven is often a scavenger, but its beak is not strong enough to tear through the thick hide of a winter-killed deer.
It will sit near the carcass and call loudly, attracting other ravens. As the mob gathers, they start making distress calls. That usually attracts a large predator, such as a wolf or coyote. They wait until the predator tears into the carcass.
At that point, 3 or 4 of them will start harassing the predator, keeping its attention, while the other ravens steal parts of the carcass. They then share what they get with the ravens that kept the predator busy.
This is an example of what kind of relationship?
-
mutualism
Yes! In mutualism, both organisms benefit. The ravens help the predator find the carcass, and the predator tears it open so that the ravens can eat some too. Both get a benefit from the relationship. -
commensalism
No. In commensalism, one organism benefits, and the other is not affected. In this case, the ravens and the predator both benefit. -
parasitism
No. For parasitism, one organism benefits, and the other is harmed. Neither the raven nor the predator is harmed by this relationship. -
predation
No. In predation, one organism eats another. Neither the raven nor the predator gets eaten in this relationship.

When Nancy and I moved from Florida to our new home in Utah, we found that many of the flowers we grew in Florida would not grow well here. Why?
-
The soil is different.
This is part of the answer. The soil here is mostly sand, and is very alkaline. The soil in Florida had much more organic matter and was more acidic. Plants that need rich soil do not grow well here. -
The climate is different.
This is part of the answer. The climate in Utah is very different from Florida. The winters are MUCH colder (down to -20°F) and the summers are MUCH hotter (up to 125°F). The climate here is also much drier. When we lived in Jacksonville, FL, we got about 52 inches of rainfall each year. Here in Utah, we only get about 14 inches of rainfall each year. Some of the plants from Florida can grow here, but the ones that cannot stand the cold, heat, and dry conditions do not. -
The animals are different.
This is part of the answer. The wildlife here is much different from the animals in Florida. There are insects here that eat plants that were not bothered by Florida insects. There are rock squirrels, western pocket gophers, jack rabbits, mule deer, and many other animals here that love to eat many kinds of flowers. Plants that do not have a bitter taste, spines, or other ways to discourage animals do not do well here. -
All of the above.
Yes! All of the answers are correct. When you take an organism from one environment and put it into another, you may see different results. If the organism is not adapted for the new environment, it may die or not grow well. If it is very well adapted to the new environment, it may take over, crowding out some of the native organisms.
