Energy transformation or conversion
When the child is moving, he/she has kinetic energy. For just a brief second before they move the other way, the child is not moving, but they have gravitational potential energy.
The child may need a push from time to time because friction with the air causes loss of energy.
The correct answer is I disagree. Elements form all pure substances, but some pure substances include elements bonded together to form molecules and compounds.
Elements are pure substances but these elements also make other things such as water. The water molecule is made of two elements called oxygen and Hydrogen. Now water itself is a pure substance as it is chemically bonded hydrogen and Oxygen but it is composed of more than one element

Most of the geologic activity happens
at the boundaries between tectonic plates where two plates meet. This activity
occurs as plates interact, such as volcanoes, earthquakes, and mountain building. Geographies that form
at a plate boundary are determine by the direction of plate motion and by the
type of crust at the boundary.
Moreover, plate boundaries has three types namely;
divergent plate boundaries where the two plates move away from each other, then
convergent plate boundaries, here the two plates move towards each other and
lastly, transform plate boundaries, in which the two plates slip past each
other.
