1. The answer is B. the asthenosphere
Asthenosphere is a layer of the Earth situated below the lithosphere. It is a semi-fluid and ductile rock or partly molten rock. Due to semi-fluid state of asthenospheric rock, it behave like a plastic and flow gradually. Thus, causes movement of continents.
2. The answer is C. collision between tectonic plates
The Earth’s crust becomes unstable when tectonic plates meet. As the plates slide past each other and push against each other. This causes earthquakes and volcanic eruptions at the edge between the plates.
Answer: B. participate in the hydrologic cycle
Explanation: Residence time of water is the rate of water in a water reservoir such as the ocean or the atmosphere divided by how fast more water is added to it or lost from it.
While residence time is thousands of years in oceans, water in the atmosphere has a short residence time of abut 10 – 11 days. This allows it to participate in the hydrologic cycle which includes evaporation and precipitation. Water in the atmosphere precipitates as snow or rain, returning to other water reservoirs.
