The topography of the earth s surface, what are the main topography of the earth s surface and what

There are five types of terrain on land, including plains, hills, plateaus, mountains, basins.

In detail, is it a form or a form.

Spherical, but uneven.

The main topographic plains, mountains, hills, plateaus, basins of the earth's surface.

They have the following characteristics:

1. Plains: below 200 meters above sea level; The surface is broad and flat; It is found on the banks of large rivers and in areas bordering the ocean.

2. Mountains: above 500 meters above sea level; The ups and downs are very large, the slope is steep, the valley is deep, and it is generally distributed in veins.

3. Hills: between 200 meters and 500 meters above sea level; The slope is gentle; It consists mainly of low mountainous terrain.

4. Plateau: above 500 meters above sea level; The terrain is not very undulating, but the edges are steep; The mountains are undulating and uneven.

5. Basin: high on all sides, low in the middle.

The topography of the earth's surface is characterized by a relatively high amount of water.

The surface area of the earth.

About the surface area is covered by water, and most of the earth's crustal surface is below sea level. The surface of the earth's crust is mountainous, including a global mid-ocean ridge system, as well as submarine volcanoes and trenches.

Submarine canyons, submarine plateaus, and abyssal plains.

The rest are places that are not covered by water, including mountains, basins, plains, plateaus and other terrain. The surface has been reshaped over a long period of time by tectonic and erosion.

Heat within the earth:

Accretion residual heat accounts for about 20% of the heat generated in the Earth's interior, and 80% of the heat of radioactive decay. Thermogenic isotopes within the Earth.

There are mainly potassium-40 and uranium-238

Uranium-235 and thorium-232.

The temperature at the center of the earth can reach up to 6000 °C and the pressure can reach 360 GPA. Because much of the geothermal heat is caused by radioactive decay, scientists speculate on the history of the Earth.

Early, in half-life.

The above content refers to Encyclopedia - Earth.

There are five basic forms of the earth's surface: mountains, plateaus, hills, plains, and basins, and the characteristics of each terrain are different.

Many changes in the earth's surface are carried out very slowly under the action of natural forces such as flowing water, wind, glaciers, and ocean waves, which are difficult for us to perceive in a short period of time. Land surface morphology is a topographic feature made up of the processes that form the shape of the ground. All land surface forms have elevation and topography, and large areas with similar surface forms are called topographic areas.

There are two states on the earth's surface, one is ocean and the other is land.

The Earth's oceans are huge, with about 71% of the Earth's surface covered by seawater. The main body of the ocean is the ocean, and the largest of the four oceans is the Pacific Ocean.

The Earth's land area is relatively small, with 29% of the Earth's surface area, six continents and many islands. Among them, the Eurasian continent is the largest land mass.

The topography of the earth's surface includes both terrestrial and seabed topography.

The terrain generally includes five types: mountains, plateaus, basins, hills, and plains.

The buried terrain of the seabed includes: continental shelf, continental slope, ocean trench, ocean basin, ridge, etc.

Hello dear, I've been waiting for a long time, I'm glad to answer for you. The reasons for the formation of today's geological landforms can be divided into two categories: internal dynamic geological processes and external dynamic geological processes.

The former mainly refers to the energy of geological processes in the earth's interior, including tectonic movements, volcanism, metamorphism, etc. The latter mainly refers to the energy of these geological processes mainly outside the earth, such as the sun, the moon, etc. This type of action mainly includes the geological action of oceans, surface water, lakes, glaciers, winds, glaciers, etc.

I hope mine is helpful to you

The various undulating forms of the land surface are collectively called terrain The terrain of the land surface is diverse, and people usually divide the land topography into five basic types: plains, plateaus, mountains, hills and basins

So the answer is: basin; Plateau

Common landforms are:

1: Flowing water landform. Erosion and accumulation of water handling.

2: Volcanic landforms.

3: Aeolian landforms. Typical Yadan landform. It is mainly due to wind erosion.

4: Bing's Xian River landform. Ice and stool river transport, accumulation, abrasion.

5: Permafrost.

6: Coastal landforms. Water erosion.

7: Karst landforms. Dissolution.

8: Danxia landform. The causes are complex, including flowing water, dissolution, and gravity collapse.
