Pangaea begins to break up and splits into two major landmasses — Laurasia in the north, made up of North America and Eurasia, and Gondwana in the south, made up of the other continents.

Where can you find a valley?

Valleys are most commonly drained by rivers and may occur in a relatively flat plain or between ranges of hills or mountains. Those valleys produced by tectonic action are called rift valleys. Very narrow, deep valleys of similar appearance are called gorges.

How many types of valleys are there?

There are three common types of valleys which include V-shaped valleys, U-shaped valleys, and flat-floored valleys.

What do valleys look like?

Valleys are depressed areas of land–scoured and washed out by the conspiring forces of gravity, water, and ice. Some hang; others are hollow. … Mountain valleys, for example, tend to have near-vertical walls and a narrow channel, but out on the plains, the slopes are shallow and the channel is wide.

Are hills landforms?

A landform is a feature on the Earth’s surface that is part of the terrain. Mountains, hills, plateaus, and plains are the four major types of landforms.

What are river valleys?

1. An elongated lowland between ranges of mountains, hills, or other uplands, often having a river or stream running along the bottom. 2. An extensive area of land drained or irrigated by a river system.

What is V-shaped valley?

What is a Delta in geography?

Deltas are wetlands that form as rivers empty their water and sediment into another body of water, such as an ocean, lake, or another river. Although very uncommon, deltas can also empty into land. A river moves more slowly as it nears its mouth, or end.

What are the 3 types of deltas?

The three main types of deltas are the arcuate, the bird’s foot and the cuspate.

Is the Nile river a delta?

The Nile delta is situated in northern Egypt, where the river Nile reaches the Mediterranean Sea. The Nile is the longest river in the world. It originates near the equator and flows nearly 7000 km northward. The Delta begins approximately 20 km north of Cairo and extends North for about 150 km.

What is bird foot delta?

Bird’s foot Delta: Named because it forms like a bird foot’s claw. This shape is created when the waves are weak and the river flow is stronger. They are formed due to deposition of finer materials by river water. Deposited alluvial material divides the river into smaller distributaries.

What is Gilbert delta?

A Gilbert delta (named after Grove Karl Gilbert) is a type of fluvial-dominated delta formed from coarse sediments, as opposed to gently-sloping muddy deltas such as that of the Mississippi. For example, a mountain river depositing sediment into a freshwater lake would form this kind of delta.

What area is considered the Mississippi delta?

The Delta covers 35,000 square miles from southern Illinois to the Gulf of Mexico, encompassing 219 counties in seven states and approximately 8.3 million people.
