Answer:
Geologists can use index fossils to match rock layers in different areas.

Answer:
True
Explanation:
The earth's ocean generates warm and cold current with respect to the location and the time of the year.
Warm ocean currents originates from the equator and flows towards the pole to balance the surrounding temperature whole cold ocean currents rises from the pole towards the equator to balance the hot equator temperature.
Answer:
The evolution of karst landscape is by the interaction of water with limestone rocks.
Explanation:
- The karst topography is formed by the dissolved soluble rocks like the limestone and dolomite and featured by the sinkholes and caves.
- The development of the karst occurs when the acidic water starts to break down the surface bedrocks and cracks open in the bedding plane, as time passes these features gets wider and leads to the development of a drainage system. Carbonic acid is one of the main mechanisms for the formation of features.
- The karst landscape has a variety of small features and these include the sinkholes, limestone payments, cave pillars, stalactites, and stalagmites. Hazards associated with the karst landscape are erosion by rivers, sinkholes, and hollow holes and Karst wells, etc.
- The relations between the groundwater and surface water are water quality and quantity. The subsurface layer creates a filter and cleans water from other impurities.
Salinity Is the measurement of minerals in the ocean waters.
