Which substance is translucent?
a. clear glass
b. cream cheese
c. tissue paper
d. orange juice

hint: translucent means: a material that allows most of the light that strikes it to pass but forms a blurry image.

C. Tissue Paper

Explanation:

When we talk about objects that are illuminated by a light source, they are classified according to the amount of light they let through them, as follows:

Transparent bodies: Those who let in almost all the light that incides them. Therefore, the intensity of the incident light is very similar to that transmitted.  For example: Clear Glass

Opaque bodies: Those who do not let the light pass.  For example: Cream Cheese and Orange Juice

Translucent bodies: Those that let in a portion of the incident light. That is, they let approximately half of the light that falls on them pass through. For example: Tissue Paper

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
