It's an area that is organized around a focal/nodal point where there is a central focus. The central diminishes as you move outwards from the point. Generally used to display information about economic activities.
Answer:
A landmass formed within a river is known as riverine islands. Riverine islands are formed when rocks and mud gets deposited in the river bed by flowing rivers.
Answer:
Principle of faunal succession
Explanation:
Principle of faunal succession -
According to this theory , the layer of the sedimentary rocks have fossils of the flora and fauna .
Which helps to study the rocks regarding the ages and the types of specifies found at that time .
It is the best method to study about the ancient lives , which helps by determining the relative age of the rocks .
Even the law of superposition is used to determine the time and age of the sedimentary rocks .
Answer:
b. wind waves, seiches, tsunami, tides.
Explanation:
The wavelength of water waves is calculated measuring the distances between the trough (low point) portion of a wave. Usually, the bigger the wave, the greater the wavelength.
wind waves: small waves caused by the wind. These waves tend to be small and with a short wavelength.
seiches: are usually waves on a lake or other closed water bassin. They can be pretty high from a human perspective, so they are definitely bigger than wind waves.
tsunami: we all know how big the waves of a tsunami can be, totally wiping out coastal cities they encounter, so that's pretty big waves, and big waves tend to be larger apart (so with a bigger wavelength) than smaller ones.
tides: yes, a tide can be considered as a huge wave... that's running throughout the planet. We barely see it as a wave because we can only see one wave at a time, the next wave being tens of thousands of mile away.
