The white lines in this piece of rock were straight when the formed. Later, the rock was squeezed by tremendous pressure that compressed the layers into squiggles. What kind of rock is it?.
-
Igneous
No. Igneous rocks formed from magma or lava. The original rock was igneous, but it has been changed and is no long an igneous rock. -
Sedimentary
No. Sedimentary rocks are bits of other rocks that have been moved and deposited. This rock was squeezed, not moved and deposited. It is not sedimentary. -
Metamorphic
Yes! Rocks that are changed by pressure and/or heat are classified as metamorphic rocks. The wavy, white lines show us that the rock has been squeezed by tremendous pressure. That tells us it is a metamorphic rock. -
None of the above.
No. All rocks are classified as either igneous, sedimentary, or metamorphic.

How can there be rain if this area is a desert?
Answer:
It is important to understand the difference between climate and weather. Weather is what is happening now. Climate is determined by looking at the weather data over a long period of time, often several decades. To be classified as a desert climate, the area has an average annual rainfall of 7.87 inches of rain or less. That tells us that it does sometimes have rain, just not very often.

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.

I poured some water on this rock. Later that day, the water was all gone. What happened to it?
-
It evaporated.
Yes. When liquid water turns into water vapor, the process is called evaporation. That is what happened to the water on the rock. -
It sublimated.
No. Sublimation is when a solid turns directly into a gas. Dry ice (frozen carbon dioxide) is an example of sublimation. The solid changes directly into carbon dioxide gas, without becoming a liquid. -
It condensed.
No. Condensation is when a gas turns into a liquid. The drops of water that form on the outside of a glass of ice is the result of condensation. -
It precipitated.
No. In weather, precipitation is when solid or liquid water falls from the clouds. Rain, snow, and sleet are examples of precipitation.
