What is the difference between speed and velocity?

  1. Speed is faster.

    No. An object's speed is part of its velocity.
  2. Velocity has to be in a specific direction.

    Yes! An object's speed is measured in distance per time, such as 20 miles per hour. Its velocity must include a direction, such as north at 20 miles per hour.
  3. They mean the same thing.

    No. The two terms have different meanings.
  4. Speed is a general term and velocity is a scientific term.

    No. Both terms are used in science, and they mean different things.

How can there be rain if this area is a desert?

Answer:

It is important to understand the difference between climate and weather. Weather is what is happening now. Climate is determined by looking at the weather data over a long period of time, often several decades. To be classified as a desert climate, the area has an average annual rainfall of 7.87 inches of rain or less. That tells us that it does sometimes have rain, just not very often.

Pine trees do not have flowers. What structure do they have that servers the same purpose?

  1. Needles

    No. Pine needles are a kind of leaf. They are not used for reproduction.
  2. Cones

    Yes! Pine cones produce pollen and seeds, just as flowers do in flowering plants.
  3. Fruit

    No. Fruit are used for dispersing seeds, not for pollination.
  4. Buds

    No. Pine tree buds produce needles. They are not involved in reproduction.

This snow fell when the temperature outside was 39°F. How can you get snow when the temperature is above freezing?

  1. The wind made it feel colder, allowing it to snow.

    No. While wind chill can make it feel colder, it does not actually make it colder.
  2. It was colder in the clouds where the snow formed.

    Yes. Even when air temperatures at the surface are above freezing, the clouds can be much colder. If the air at the surface is not too warm, the snow can reach the ground without melting.
  3. Rain froze into snow when it hit the ground.

    No. Freezing rain forms ice, not snow. Light, fluffy snow flakes form as they fall through the air, not after they hit the ground.
  4. This is really hail instead of snow.

    No. Hail is made of large chunks of ice, not tiny flakes.

Notice that the very back point on this Mule Deer's antlers is split. This is a genetic trait which is becoming more and more common because hunters would rather shoot deer with perfect antlers. This is an example of:

  1. why hunting deer is a bad idea.

    No. Actually, deer hunting is very important. Because we have killed off many of their natural predators, if hunters did not control their population, large numbers of them would starve to death.
  2. an adaptation that improves an organism's chance for survival.

    Yes. Because hunters are less likely to shoot it, this deer is more likely to survive long enough to reproduce, passing this trait on to its offspring.
  3. an acquired trait.

    No. This is a genetic trait, not an acquired trait.
  4. why antlers are more useful than horns.

    No. Antlers and horns serve different functions, but both are useful to the animal that has them.

UT.5.V.2.c Describe how a particular physical attribute may provide an advantage for survival in one environment but not in another (e.g., heavy fur in arctic climates keep animals warm whereas in hot desert climates it would cause overheating; flippers on such animals as sea lions and seals provide excellent swimming structures in the water but become clumsy and awkward on land; cacti retain the right amount of water in arid regions but would develop root rot in a more temperate region; fish gills have the ability to absorb oxygen in water but not on land).

UT.7.IV.2.a Predict why certain traits (e.g., structure of teeth, body structure, coloration) are more likely to offer an advantage for survival of an organism.
