What causes slab pull in earth’s crust? a. the movement of salt water near deep ocean beds b. thick portions of earth’s crust colliding with thinner portions c. convection currents within earth’s molten mantle d. solar winds moving charged particles into earth’s atmosphere

c - convection currents within earths molten mantle.

Explanation:

The warm material rises since it is less dense and lighter whereas cool material sinks down as it is heavier and denser. This movement of warm and heavy material creates circulation patterns in the atmosphere, water and in the mantle of Earth which are known as convection currents.

Thus, the correct answer is option c.

answer : haversian

[explanation: -(compact bone is organized as parallel columns, known as haversian systems, which run lengthwise down the axis of long bones. these columns are composed of lamellae, concentric rings of bone, surrounding a central channel, or haversian canal, that contains the nerves, blood vessels, and lymphatic system of the bone)]
