Sedimentary rock formation involves all

the following processes except —

• erosion

• deposition

• melting

• compaction

Students were asked to compare the masses of

equal size cylinders made from different materials.

The left side of the scale weighs more than the right

side. The mass of each cylinder is shown in grams.

How could a student balance the left side and the

right side of the scale?

• Move a 100 gram cylinder from the right side of

  the scale to the left side

• Move a 50 gram cylinder from the left side of

  the scale to the right side

• Move a 100 gram cylinder from the left side of

  the scale to the right side

• Move a 50 gram cylinder from the right side of

  the scale to the left side

Jane Goodall is a famous

scientist. She has spent her entire

career studying chimpanzees. One

of her major discoveries was that

some groups of chimps have

learned how to use tools such as

prodding sticks to get termites out

of holes and rocks to break open

nuts.

Which scientific observation

listed below did NOT help Jane

Goodall and other scientists

conclude that using tools was

a learned trait in chimps?

• The older chimpanzees teach the younger chimpanzees to strip leaves

  off sticks and put them in termite holes.

• Chimps break open nuts that grow there.

• Chimps use a larger stick to dig a hole in the termite mound and a smaller

  stick to dig out the termites.

• Wild chimps live in Africa and their diet consists of fruits, nuts, seeds, leaves

Below are drawings of two different types of elephants. One lives in Africa and one lives in Asia. Elephants release a lot of heat from their ears, helping them to keep cool when it is hot outside. They can also flap their ears to help cool themselves off.

Based on the information above and the pictures of the elephants, which elephant lives

in Africa and why?

• Elephant A lives in Africa because its ears are larger, and Africa is cooler than Asia.

• Elephant B lives in Africa because its ears are smaller, and Africa is cooler than Asia.

• Elephant A lives in Africa because its ears are larger, and Africa is hotter than Asia.

• Elephant B lives in Africa because its ears are smaller, and Africa is hotter than Asia
