Question

a measure of how fast an objects particles are moving is ________. temperature boiling melting a device that measures temperature is a(n) ______. device thermometer convection hot liquid rock inside the earth is ______. metamorphic rock magma extrusive rock the earths ________ is made of large plates. surface crust

Explanation:

1. Temperature is defined as a measure of the average kinetic energy of an object's particles, meaning it reflects how fast the particles move. Boiling and melting are phase changes, not measures of particle speed.
2. A thermometer is a specialized device designed to measure temperature. "Device" is too general, and convection is a heat transfer process.
3. Magma is the term for hot, liquid rock located beneath the Earth's surface. Metamorphic rock is altered by heat/pressure, and extrusive rock is magma that has erupted onto the surface (called lava once erupted).
4. The Earth's crust (along with the upper mantle forms the lithosphere) is broken into large, moving tectonic plates. The "surface" is a vague term, while the crust is the specific layer made of these plates.

Answer:

1. A. temperature
2. B. thermometer
3. B. magma
4. B. crust
