This limestone is in Middle Tennessee, and contains a wide variety of fossils of ocean creatures. What kind of rock is limestone?
-
Igneous
No. Igneous rocks are formed from molten lava or magma. -
Sedimentary
Yes! Sedimentary rocks are made up of bits of other rocks that have been deposited by wind, water, ice, or gravity. This limestone was deposited by the ocean, making it a sedimentary rock. -
Metamorphic
No. Metamorphic rocks have been changed by heat and/or pressure. If this limestone was exposed to tremendous heat and pressure, it could change into a metamorphic rock called marble. -
Limestone is not a rock.
No. Limestone is a naturally occurring solid that forms large layers in the Earth. It is a rock.

This is called Quartzite. It was once sandstone, but heat and pressure changed it by fusing the grains of sand to each other, making it much harder. What kind of rock is it?.
-
Igneous
No. Igneous rocks formed from magma or lava. That would have melted the sand grains. 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 sandstone it was a sedimentary rock. -
Metamorphic
Yes!. This quartzite been changed by heat and pressure from a different kind of rock. It is metamorphic. -
Quartzite is not a rock.
No. Quartzite is a naturally occurring solid that forms large layers in the Earth. Quartzite is a rock.

When you mix cornstarch and water, you get something that many science sites call Oobleck. Under pressure, it feels like a solid, but when the pressure is removed, it flows like a liquid. What state of matter is it?
Answer:
This is a mixture, made up of particles of solid matter surrounded by a liquid. The mixture is not a single state of matter.
This is an important concept to understand, and it is seen in many things we use every day. A good example is the Egg States video, showing how a mixture of liquid and gas can seem to be a solid.
Before you try to decide if something is solid, liquid, gas, plasma, or some other state of matter, first make sure that it is a pure substance, and not a mixture of different states.

What season is Australia having in this graphic?
-
Spring
No. In the spring, the Earth's axis would not be tilted towards or away from the Sun. -
Summer
Yes! Australia is in the southern hemisphere, which is tilted towards the Sun. That tells us that it is summer there. -
Autumn
No. In the autumn, the Earth's axis would not be tilted towards or away from the Sun. -
Winter
No. Australia is in the southern hemisphere. If it was having winter, then the southern hemisphere would be tilted away from the Sun.
