Which statement explains how convection currents affect the movement of plates?
1.Gravity pulls one edge of a plate down into the mantle, which causes the rest of the plate to move as well.
2.Heat from Earth’s interior causes lithospheric plates to collide at convergent plate boundaries, causing volcanoes.
3.Heat from Earth’s interior causes currents of hot rising magma and cooler sinking magma to flow, moving the crust along with them.
4.As convection currents drift across the oceans, they bring the pieces of Earth’s crust with them as the supercontinent breaks apart.

Put the following steps of the convection process in the correct order. 1. gravity pulls cooler matter downward. 2. the matter expands and decreases in density. 3. an up-and-down flow of matter produces a convection current. 4. matter is heated. 5. warmed matter is forced upward. question 2 options: a) 4, 2, 5, 1, 3 b) 2, 4, 3, 1, 5 c) 3, 2, 5, 4, 1 d) 1, 4, 2, 5, 3

Four different thermometers were used to measure the temperature of a sample of pure boiling water. the measurements are recorded in the table below. thermometer temperature reading 1 temperature reading 2 temperature reading 3 w 100.1°c 99.9°c 96.9°c x 100.4°c 102.3°c 101.4°c y 90.0°c 95.2°c 98.6°c z 90.8°c 90.6°c 90.7°c the actual boiling point of pure water is 100.0°c. what can be concluded from the data about the reliability and validity of the thermometers?
