What are some surface features on Earth?

Mountains, plains, and buttes (like these) are all 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. Minor landforms include buttes, canyons, valleys, and basins.

What are physical features?

Physical characteristics are defining traits or features of a person's body. These are aspects of appearance that are visually apparent to others, even with no other information about the person. They can include a variety of things. Hair and facial features play a big role but aren't the whole picture.

How are surface features formed?

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.

What is Microsoft Surface?

Surface is the brand name for a variety of computing devices manufactured by Microsoft. These devices include the Surface Go, Surface Pro, Surface Laptop, Surface Book, Surface Studio, and Surface Hub (with new variations of each being released periodically).

Microsoft Surface for Business

Modern businesses need strong enterprise mobility to remain competitive. Being able to allow employees to work remotely can help:

Microsoft Business Security

In any enterprise, business security is a constant concern. A data breach could cost millions (around $3.86 million, according to Ponemon) as your business works to restore damaged systems, prevent future breaches, and provide reparations and security to any affected customers. Needless to say, security breaches should be avoided whenever possible.

Why are surface features important for biomaterials?

Generally, surface features on biomaterials give rise to increased material surface area, resulting in protein and cellular reactions that are increased relative to a smooth surface of the same biomaterial. Roughness on the surface of a static device within flowing blood is likely to capture cells that would otherwise flow downstream away from the site of activation. Thus, in most cases, surface features are not helpful in improving the biocompatibility of blood-contacting devices.

How to create microtopographical features?

Another method to produce microtopographical surface features is to simply copy them from a surface which already contains the microtopography. When a natural surface is copied it is referred to as biomimicry. A common technique used involves taking a polyvinylsiloxane impression of the surface. This takes a negative copy of the surface features; the negative is then filled with a high-resolution epoxy resin to create a positive mould (Marrs et al. 1995 ). This technique allows copying of surface features to the nearest micrometre; it can also be used on wet samples and several replicates of the same surface can be produced by re-using the negative impression. Creating mimics of natural surface features separates physical and chemical effects which may be acting on the natural surface by testing only the surface microtopography. The disadvantage of this technique is that it is limited to a resin substrate, it is difficult to scale-up in size, and inaccurate curing of the surface will result in imperfections. Studies which have used this technique to create biomimics and examine their antifouling properties include: ( Bers et al. 2006b; Bers and Wahl 2004; Marrs et al. 1995; Scardino and de Nys 2004 ).

Why is surface roughness important?

Roughness on the surface of a static device within flowing blood is likely to capture cells that would otherwise flow downstream away from the site of activation. Thus, in most cases, surface features are not helpful in improving the biocompatibility of blood-contacting devices.

Why are nanotopographical structures important?

Nanotopographical structures could be used to more precisely control the adsorption of specific proteins, in defined orientations and conformations. However, such investigations are at an early stage of research, but may in future provide better control of long-term performance of blood-contacting biomaterials.

What are the features of the Earth's surface?

Surface Features. The Earth's surface is composed of rigid plates that move relative to each other. The plates have three main motions, and each one has different results. 1) When two plates collide, one may be forced under the other causing ocean trenches, volcanic islands, and mountain ranges. 2) When two plates move away from each other, rifts ...

What are the features of a plate boundary?

3) When two plates slide past each other, there are faults. Features such as volcanoes and earthquakes exist mainly along the plate boundaries. Most moons and some planets have many impact craters, however these are rare features on Earth.

What are the most visible features of the Sun?

The most noticeable surface features of the Sun are cooler, darker areas known as sunspots ( Figure below ). Sunspots are located where loops of the Sun’s magnetic field break through the surface and disrupt the smooth transfer of heat from lower layers of the Sun, making them cooler, darker, and marked by intense magnetic activity.

What are solar prominences?

Solar prominences are the plasma loops that connect two sunspots. Solar flares and coronal mass ejections are eruptions of highly energetic particles that can erupt from the Sun's surface and cause problems with power grids and communications on Earth.

How long does a solar prominence last?

Prominences can last lengths of time ranging from a day to several months.

What is a solar flare?

Term. Definition. solar flare. a violent explosion on the Sun’s surface. solar prominence. plasma loop flowing between sunspots. sunspot. cool, dark area on the Sun’s surface that have lower temperatures than surrounding areas; sunspots usually occur in pairs and come and go on an 11-year cycle.

How do sunspots occur?

Sunspots usually occur in pairs. When a loop of the Sun’s magnetic field breaks through the surface, a sunspot is created where the loop comes out and where it goes back in again. Sunspots usually occur in 11-year cycles, increasing from a minimum number to a maximum number and then gradually decreasing to a minimum number again. (a) Sunspots.

What is the Earth made of?

Earth is mostly made up of iron, magnesium, oxygen and silicon. 70% of the Earth’s surface is covered in water that is why Astronauts have dubbed it as the Blue Planet. The other 30% is land that are tectonic plates that have shifted through time with some rising above sea level, the other plates have submerged and some appearing ...

Why do tectonic plates exist?

The existence of life is attributed to the movement of tectonic plates that allow for carbon dioxide recycling and prevent runaway greenhouse effect. The tectonic plates on Earth prevent it from getting too hot and eventually lead to the same fate as its sister planet Venus.

How thick is the South Polar Cap?

The south polar cap usually spans about 217 miles (350 km) with a total thickness of about 1.8 miles (3 km), and contains about 25%-30% of the planets’ atmosphere in the form of frozen carbon dioxide. Copious amounts of water are then released when it sublimes in the Martian summer, forming vast cirrus clouds in the process.

Why are there blue ridges on the dunes?

The blue ridges on the dunes are the result of image enhancement processes that allow investigators to differentiate easily between elevations, textures, and angles of illumination in images taken by the HiRISE (High Resolution Imaging Science Experiment) camera on board the orbiter.

How high are the dunes on Mars?

Spotted by the Mars Reconnaissance Orbiter that can resolve objects as small as a meter on the surface, these dunes were snapped from an altitude of 157.8 miles (25 2.4 km) when the Sun was at an angle of about 53° above the horizon.

Is the northern plains lower than the southern hemisphere?

Supporting this controversial theory is the northern martian surface being less heavily cratered than in the southern hemisphere, as well as shoreline-like geographic features, and the northern plains being lower than in the southern hemisphere, just like the ocean basins back here on Earth.
