Which of the following is not a method of heat transfer?
conduction |
|
reflection |
|
radiation |
|
convection |
Heat is always transferred from warmer to cooler environments through conduction, convection, or radiation.
"An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force." This describes which of Newton's laws of motion?
fourth |
|
second |
|
first |
|
third |
Also known as the law of inertia, Newton's first law of motion states that An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Materials like metals that transfer heat efficiently are called:
insulators |
|
reflectors |
|
conductors |
|
refractors |
Heat is always transferred from warmer to cooler environments and conduction is the simplest way this transfer can occur. It is accomplished through direct contact between materials and materials like metals that transfer heat efficiently are called conductors while those that conduct heat poorly, such as plastic, are called insulators.
The ozone layer is in which of Earth's atmospheric layers?
mesosphere |
|
thermosphere |
|
stratosphere |
|
troposphere |
The stratosphere is just above the troposphere and is stratified in temperature with warmer layers higher and cooler layers closer to Earth. This increase in temperature is a result of absorption of the Sun's radiation by the ozone layer.
Herbivores are __________ that subsist on producers like plants and fungus.
secondary consumers |
|
primary consumers |
|
tertiary consumers |
|
scavengers |
Primary consumers (herbivores) subsist on producers like plants and fungus. Examples are grasshoppers, cows, and plankton.
