This is Johnson Wash, that runs down the middle of the canyon where we live. It is usually dry, but when it rains up north, we get flash floods. Is this an example of erosion, weathering, both, or neither?
-
Erosion
Yes, the is partially correct! You can tell by the muddy appearance of the water that it is carrying sand, clay and dirt along with it. Erosion is when bits of rock are moved by wind, water, ice, or gravity, so this counts as erosion.. -
Weathering
Yes, the is partially correct! The term "weathering" causes confusion because it sounds like it has something to do with weather. In Earth Science, weathering means "breaking apart." Weathering breaks rocks apart into smaller bits. The fast moving water causes smaller rocks to smash into larger rocks, breaking them apart. -
Both erosion and weathering
Yes! The flash flood in this photo is causing weathering, and erosion. As the flood decreases, and the water slows down, it will drop the sand, clay, dirt, and rocks in a process called deposition. -
Neither erosion nor weathering
No. This flash flood is causing both weathering and erosion.

Baking a cake is an example of:
-
A physical change
Partly right. Some of the changes involved in baking a cake are physical changes. -
A chemical change
Partly right. Some of the changes involved in baking a cake are chemical changes. -
Both
Yes! The process of baking a cake involves many changes. Some, such as water evaporating and sugar melting are physical changes. Others, such as baking powder reacting cause a change in the chemical formulas, indicating a chemical change. For more on this, read Changing How We Look at Changing -
Neither
No. There are many changes involved in baking a cake.

The Earth stays in orbit around the Sun because:
-
The Sun's gravity pulls on the Earth
This is only part of the answer. -
The Earth's gravity pulls on the Sun
This is only part of the answer. -
The gravity of the Sun and the Earth pull on each other
Yes! The gravitational attraction between the Earth and the Sun is a result of both the Sun pulling on the Earth and the Earth pulling on the Sun. -
Gravity does not keep the Earth in its orbit.
No. Without the pull of gravity, the Earth would continue moving in a straight path instead of curving around the Sun.

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.
