What type of landforms are found in the Ethiopian highlands?
Its geomorphology varies from highlands marked by high volcanoes and incised by deep river gorges to the rift valley lakes endorheic systems and the below sea level lowlands with characteristic landscapes which are unique in the world.
What two geologic processes are we using to describe landforms describe how these geologic processes shape landforms?
Tectonic plate movement under the Earth can create landforms by pushing up mountains and hills. Erosion by water and wind can wear down land and create landforms like valleys and canyons. Both processes happen over a long period of time sometimes millions of years.
What would you expect to have happened as the Earth or any other planet cooled after its formation?
What would you expect to have happened as the Earth (or any other planet) cooled after its formation? The hard crust thickened closing off volcanic vents and the mantle began to solidify slowing the motion that causes volcanism and tectonics. … Part of the planet’s interior is liquid.

What are the 4 types of endogenic processes?
The most familiar endogenic processes involve vulcanism metamorphism earthquakes crustal warping folding and faulting .
What are the 4 geological features?
There are peaks valleys jagged edges rolling hills and everything in between. In general we call these geological features but this term is very broad and refers to any of the physical features on Earth’s surface. You might also hear them referred to as landscapes topography and landforms.
What are 3 geological features?
You learn about volcanos mountains (also called hills or mountains) and canyons. These three features are some of the most well-known geologic features on Earth but they aren’t the only ones.

What does geology consist of?
Definition of Geology: Geology is the study of the Earth the materials of which it is made the structure of those materials and the processes acting upon them. It includes the study of organisms that have inhabited our planet.

Tracing Early History of Plate Tectonics. Geological processes are ultimately consequences of Earth’s cooling with time as well as the plate tectonics which is controlled by the secular cooling of the mantle (Niu 2014 Condie 2016).
What are the major geological process of Ethiopia?
The geology of Ethiopia includes rocks of the Neoproterozoic East African Orogeny Jurassic marine sediments and Quaternary rift-related volcanism. Events that greatly shaped Ethiopian geology is the assembly and break-up of Gondwana and the present-day rifting of Africa.
What are major landforms in Ethiopia?
The country’s main geomorphological landscapes regions are identified as follows: (1) the northern highlands including (i) the volcanic plug belt of Adwa (ii) the central highlands and (iii) the southwestern highlands (2) the Rift Valley which consists of three main portions namely the northern central and …
Who explained how geological processes have shaped the earth?
The idea that the laws that govern geologic processes have not changed during Earth’s history was first expressed by Scottish geologist James Hutton who in 1785 presented his ideas—later published in two volumes as Theory of the Earth (1795)—at meetings of the Royal Society of Edinburgh.

What are the four major geologic processes that have shaped the surfaces of the terrestrial planets Mercury Venus Earth Mars and the moon?
figures and/or photographs. The processes involve include the following: Volcanism Tectonism (evidence of plate tectonics) Gradation (leveling of the surface due to erosion and deposition) and Impact Cratering.
What are 5 geological features?
Examples of Geologic Features Erosion produces geologic features such as valleys canyons river channels bays caves and cliffs. A few geologic features that result from deposition are deltas beaches sand dunes and stalactites.

Why did the terrestrial planets lose their primary atmospheres?
Why did the terrestrial planets lose their primary atmospheres? Their low gravities couldn’t hold them. Which molecule moves with the fastest average speed in the Earth’s atmosphere in thermal equilibrium? … UV light would break apart the water molecules and the hydrogen would be lost into space.
What are the processes that shape the Earth’s surface?
The physical processes on Earth create constant change. These processes—including movement in the tectonic plates in the crust wind and water erosion and deposition—shape features on Earth’s surface. See also what effect did the industrial revolution have on slavery
What Are The Four Major Geologic Processes That Can Shape A Planet’s Surface??
What processes shape Earth’s surface? The four major geological processes are impact cratering volcanism tectonics and erosion.
What are the 4 basic processes that shape planetary surfaces?
Explanation: The four common Planet Surface Processes are: Cratering Volcanoes Erosion and Weathering (chemical and physical). Accretion collisions and radioactive decay would be required in the formation.

What are some examples of geologic processes?
Geological processes – volcanoes earthquakes rock cycle landslides Plate boundaries include transform convergent divergent.
What geologic features form from surfaces?
As these plates slowly move about they interact with each other forming boundary zones. Each of these different types of plate boundaries produces unique geographical features on the surface including fault lines trenches volcanoes mountains ridges and rift valleys.
What are geological features might form at the surface of plate A?
Deep ocean trenches volcanoes island arcs submarine mountain ranges and fault lines are examples of features that can form along plate tectonic boundaries.

What are the major geological processes and the resulting landforms of Ethiopia?
The external (exogenic) processes include weathering mass transfer erosion and deposition. They act upon the volcanic and structural landforms by modifying roughening and lowering them down. The landmass of Ethiopia as elsewhere is the result of the combined effect of endogenic and exogenic processes.

What are the four things that cause weathering?
Weathering breaks down the Earth’s surface into smaller pieces. Those pieces are moved in a process called erosion and deposited somewhere else. Weathering can be caused by wind water ice plants gravity and changes in temperature.

Geologic Processes Melting – responsible for creating magmas that result in volcanism. Deformation – responsible for earthquakes volcanism landslides subsidence. Isostatic Adjustment due to buoyancy – responsible for earthquakes landslides subsidence. Weathering – responsible for landslides subsidence.
