Front

What type of sediment is most subject to erosion?

Back

Sand is the type of sediment most subject to erosion.

Front

What are mid-ocean ridges recognized as?

Back

Mid-ocean ridges are recognized as divergent plate boundaries.

Front

What type of tides are created when the sun and moon are at a right angle to each other?

Back

When the sun and moon are at a right angle to each other, they create neap tides.

Front

Which tide has the smallest tidal range?

Back

Neap tide has the smallest tidal range.

Front

What type of plate boundary is the Mariana Trench located at?

Back

The Mariana Trench is located at a convergent plate boundary.

Front

Define sediment. What role does it play in marine processes?

Back

Sediment refers to particles of organic or inorganic matter that accumulate in a loose, unconsolidated form. It plays a crucial role in marine processes by influencing coastal dynamics, habitats, and the geological features of the ocean floor.

Front

What is the difference between divergent and convergent plate boundaries?

Back

Divergent plate boundaries occur where tectonic plates move apart, leading to the formation of new crust, while convergent plate boundaries occur where plates collide, often resulting in subduction and the formation of mountains or trenches.

Front

Explain the concept of tidal range. What factors influence it?

Back

Tidal range is the vertical difference between the high tide and low tide. It is influenced by the alignment of the sun and moon, the shape of the coastline, and local geographical features.

Front

What are the primary forces that cause ocean tides?

Back

The primary forces that cause ocean tides are the gravitational pull of the moon and the sun on Earth's oceans.

Front

What is the significance of neap tides in marine ecosystems?

Back

Neap tides are significant in marine ecosystems as they result in lower tidal ranges, which can affect the distribution of marine organisms and the availability of nutrients in coastal areas.
