If a large volcano that is on an island erupts, it will impact the local ecosystem. Give one way how.
1. Lava will run down from the volcano, burning down all the trees around the volcano. 2. When the volcano erupts, it will throw dust into the air affecting plants across the island. 3. The magma will run into the ocean around the island, killing coral reef animals.

Wildebeest are cow like animals with horns. They migrate in herds across Africa in search of the grasses they feed on. Wildebeests are prey for lions. Predict the impact that a drought would have on the wildebeest population.
Wildebeest will be affected negatively by the drought as they will not have grass to feed on.

Janie gathered 4 different kinds of rock samples — granite, limestone, marble, and sandstone — and 4 trays. She tilted the trays, put a rock sample on the top end of each tray, and used a pump to force water continuously through a tube over the rocks for four days (96 hours). She checked each rock sample after each day. The purpose of Janie’s investigation is to determine — A the effects of weathering on different kinds of rocks B what kind of rock particles are suitable for purifying water C how changes in the rate of water flow affect different kinds of rocks D the effects of pH on different kinds of rocks
A the effects of weathering on different kinds of rocks

When a ramp was set at 90 degrees, it took 10 N of force to move a 1 kg object. When the ramp was set at 60 degrees, it took 8.6 N of force to move the 1 kg object. When the ramp was set at 30 degrees, it took 5 N of force to move the 1 kg object. What conclusion can be made with the above data?
The steeper the ramp, the more force has to be used. The less steep the ramp, the less force has to be used.
