Explain about major landforms

Answers

Answer:

Explanation:

Major landforms are the prominent physical features that make up the Earth's surface. These natural features are a result of various geological processes that have occurred over millions of years. Landforms can vary in size, shape, and elevation and are a crucial part of the Earth's geography. Here are some major landforms and explanations of each:

Mountains: Mountains are elevated landforms with steep slopes and peaks. They are often formed by tectonic plate collisions, where one plate is pushed over or under another, causing the Earth's crust to rise.

Plateaus: Plateaus are flat, elevated landforms that are higher than the surrounding areas. They are typically formed by volcanic activity or the uplift of the Earth's crust.

Hills: Hills are smaller and less steep than mountains. They are often formed by erosion, tectonic activity, or volcanic processes.

Valleys: Valleys are low-lying areas between hills or mountains. They are often carved out by the erosional forces of rivers or glaciers.

Plains: Plains are flat or gently rolling landforms that cover large areas. They are typically created by the deposition of sediment over time and are often fertile and suitable for agriculture.

Plate Boundaries: These are the areas where tectonic plates meet. There are three types of plate boundaries: divergent (plates move away from each other), convergent (plates move toward each other), and transform (plates slide past each other). These boundaries are associated with various landforms, including mountains, valleys, and rifts.

Deserts: Deserts are arid regions with minimal precipitation. They can feature various landforms, such as sand dunes, rocky terrain, and salt flats.

Coastlines: Coastlines are where land meets the ocean. They can feature various landforms, including beaches, cliffs, and estuaries. Coastal landforms are shaped by a combination of erosion, sediment deposition, and tides.

Canyons: Canyons are deep, narrow valleys with steep sides, often carved by rivers or erosion over time. Famous examples include the Grand Canyon in the United States.

Islands: Islands are landmasses surrounded by water. They can be formed through volcanic activity, tectonic plate movement, or the rising sea level.

Peninsulas: Peninsulas are landforms that are almost entirely surrounded by water but are connected to the mainland by a narrow strip of land.

Caves: Caves are underground cavities typically formed by the dissolution of limestone or other soluble rocks over time. They can feature unique geological formations like stalactites and stalagmites.

Fjords: Fjords are narrow, deep inlets of the sea that are often surrounded by steep cliffs. They are created by glacial activity and subsequent sea-level rise.

These are just a few examples of major landforms found on Earth. Landforms play a significant role in shaping our planet's geography and influencing various natural processes, ecosystems, and human activities.

The erosional process which causes rock to change into soil is called weathering. a. True
b. False

Answers

Answer:

a. True

Explanation:

Weathering is the process of transformation of rocks by disintegration (physical) or decomposition (chemical) of their structures, giving rise to sediments and interfering with sedimentary processes such as erosion, diagenesis and pedogenesis (soil formation).

Rocks appearing on the surface become exposed to external or exogenous relief transforming agents such as water and wind force. As a result, they disintegrate in oxidation or “washing” processes of their covers, and remain exposed to temperature variations. All of these effects are considered weather events.

The erosional process which causes rock to change into soil is called weathering.
a. True

What are five cities located south of 30° north latitude and west of 15° east longitude?

Answers

Answer:

They are Brazzaville and the Kinshasa, Luanda, the Libreville, and the Monrovia

Explanation:

The Brazzaville is found in the republic of the Congo in the central Africa, and form a larger area of the Congo River and is 506 km in length, and similar the Kinshasa lies in the southern banks of the river Congo, is directly cross the Brazzaville.

The Libreville is the largest capital city of the Gabon and is a trade center of the timber region. And has a major industrial and a residential area. It has a tropical equatorial climate.

Considering the map information, the five cities located south of 30° north latitude and west of 15° eastlongitude are the following:

For south of 30° north latitude: this means the cities between 0°N to 29°N latitude.

Hence, some of the five cities are the following:
