When exploring sand dunes and observing the effects of wind erosion and deposition, the best tools to use include a hand lens for close-up observations of sand grain textures and a small compass or GPS device to navigate the terrain. A field notebook can be useful for recording observations and sketches. Binoculars may also help in observing the larger landscape features from a distance.
The study of changes to materials caused by light is known as photodegradation or photochemistry. This field explores how light can alter the properties and structure of materials over time.
Changes in physical properties: cooling is temperature decrease caused by heat exchange
Discovering the essential Universe by Neil F. Comins fourth edition Extrasolar planets can be discovered by observing them indirectly by using microlensing, by observing the Doppler shift of the star due to the pull of the orbiting planet, by observing the periodic variation of the proper motion of a star, and by observing the periodic variation of the starlight due to the planet passing between that star and Earth, an event called a transit.

In the longest term changes in climate are caused by changes in the sun's output. Over shorter terms there are many different causes.
What changes are caused to the epidermis by medication?
The changes are caused by the weight of air above it.

Motion of a fluid (liquid or gas) caused by density changes caused by temperature changes.
It is caused by the position of the moon that eventually changes because of its revolution and rotation.
This is caused by changes of air pressure in your middle ear.

The seasons are the most obvious changes.
In the "Counterfeit Island" on Poptropica, the pattern of the paint sample chemical test involves mixing three chemicals - each one changes the color of the paint sample. By observing the color changes caused by each chemical, players can identify the counterfeit painting among the three samples.

A benign pap smear with severe inflammation is usually caused by an infection or atrophic vaginitis. Reparative changes are changes that are caused by the inflammation present.
