(Redirected from Embayment)
A 'headland' is an area of land adjacent to water on three sides. A 'bay' is the reverse, rather an area of water bordered by land on three sides. A large headland may also be called a '
peninsula'. Long, narrow and high headlands may be called 'promontories'. When headlands dramatically affect the
ocean currents they are often called 'capes'. A large bay may also be called a 'gulf', '
sound' or '
bight'. A narrow bay may also be called a '
fjord' if its sides are relatively steep. Any bay may include other bays (for example,
James Bay is a bay within
Hudson Bay).
Formation
A 'headland' is a piece of land that juts into the sea from the main land coast line. Headlands are shaped by erosion. They are formed when the sea attacks a section of coast consisting of alternating bands of hard and soft rock. The bands of soft rock such as sand and clay, erode more quickly than those of more resistant hard rock such as chalk. This would form a headland.
A bay is an area of water bordered by land on three sides. Bays are found between headlands where there are alternating outcrops of resistant rock and less resistant rock. Waves erode the areas of softer rock more rapidly to form bays.
Geology and geography
Headlands and bays are often found together on the same stretch of coastline. Headlands and bays form on
discordant coastlines, where bands of rock of alternating
resistance run perpendicular to the coast. Bays form where weak (less resistant) rocks (such as
sands and
clays) are eroded, leaving bands of stronger (more resistant) rocks (such as
chalk,
limestone,
granite) forming a headland, or
peninsula.
Refraction of waves occurs on headlands concentrating wave energy on them, so many other
landforms, such as
caves,
natural archs and
stacks, form on headlands. Wave refraction disperses wave energy through the bay, and along with the sheltering effect of the headlands this protects bays from storms. This effect means that the waves reaching the shore in a bay are usually
constructive waves, and because of this, many bays feature a
beach. A bay may be only
metres across, or it could be hundreds of
kilometres across.
Sometimes bays form where movements of the earth's
crust (
tectonics) bring areas of land together, or move them apart. Usually these bays are referred to as
seas or
gulfs and not bays.
"Capes and bays geography" is a derogatory term for the approach to teaching
geography that requires students to
learn by rote the names of large number of geographical features rather than taking a more theoretically driven approach.
