Characteristics used to describe matter are called physical properties. Therefore, option A is correct.
What are physical properties?A physical property of matter can be defined as a characteristic of a substance that can be evaluated without changing the identity of the material. For example, silver is shiny metal, that shows malleability, and conducts electricity.
Physical properties can be measured without altering the chemical composition of matter. Physical properties include density, malleability, electrical conductivity, color, solubility, hardness, melting point, and boiling point. There are two kinds of physical properties which are intensive and extensive properties.
Chemical properties can be described by their potential to chemical change by virtue of their chemical composition. The elements, chemical bonds, and electrons are involved in the chemical change.
Physical properties are general characteristics that describe matter. They have characteristics such as shape, size, color, and mass. These characteristics can be observed without changing the identity of the matter.

what are tectonics wegener theory
Answer:
Alfred Wegener first presented his hypothesis to the German Geological Society on 6 January 1912. His hypothesis was that the continents had once formed a single landmass, called Pangaea, before breaking apart and drifting to their present locations.Plate tectonic theory had its beginnings in 1915 when Alfred Wegener proposed his theory of "continental drift." Wegener proposed that the continents plowed through crust of ocean basins, which would explain why the outlines of many coastlines look like they fit together like a puzzle.

Answer:
1. True.
2. False.
3. True.
4. True.
Explanation:
Ridge push is also known as gravitational sliding plate that happens at mid-ocean ridges. Slab pull is the pulling force exerted by a cold oceanic plate that is denser go inside into the mantle due to its weight. Slab pull is the other process that is responsible for the movement of tectonic plate. When the hot less denser particles cool down, they sinks due to their more mass and the other less dense particles rises up.

During most of the Mesozoic Era, the Earth was ________. A.warmer than present B.about as warm as present C.cooler than present D.experiencing wild temperature fluctuations E.Unclear from the data presented. If you choose this answer explain what you are seeing.
Answer:
A.warmer than present
Explanation:
During most of the Mesozoic Era, the Earth was warmer than present.
This is because during the Mesozoic era the land were far away from water bodies which led to prevalence of deserts while today the land are much more closer to the water bodies. It’s a known fact that water bodies help in the thermoregulation and cooling of the atmosphere.
This is the main and feasible reason why the Earth was warmer in the Mesozoic era than now.

There are two continents with an ocean between them. Today, the continents
have very different plants and animals on them. However, a geologist found
fossils of the same type of organism on both continents. Millions of years ago, when this type of organism was alive, we know it lived in only one place. The geologist is using the fossils as evidence to argue that the two continents used to be touching. How could the continents have gotten so far apart, and how long did it take for this to happen?
Answer:
The continents drifted like the theory in 1912 by Alfred Wegener, moving by mere CM every year, and one day the plates will move back together due to the sea floor drift slowing moving During the BC age.

Sunspots are associated with regions of
It is visible on the
1. Decreasing magnetic field
2. Increasing magnetic field
3. Chemical combustion
4. Increasing electric field
1. Photosphere
2. chromosphere
3. Corona
4. Core
Answer:
Sunspots are associated with regions of increasing magnetic field. It is visible on the photosphere.
Explanation:
The region of the Sun that is visible to us is the photosphere. It is the lowermost layer of the solar atmosphere. This is the layer where the energy from the interior of the Sun bubbles up and is released as visible light.
One hypothesis is that sunspots are created by changes in magnetic fields in the Sun. Sunspots usually occur in pairs over regions of intense magnetic activity.
Hope the helps and have a nice day!!
Sunspots are associated with regions of increasing magnetic field. It is visible on the Photosphere.
A sunspot is an area on the Sun with a magnetic field that is about 2,500 times stronger than the Earth's. When there is a strong magnetic field, the magnetic pressure increases while the surrounding atmospheric pressure decreases.
As we know, the photosphere is the visible surface of the Sun. Due to the Sun's gaseous nature, this is not a solid surface but an atmospheric layer that measures about 100 km thick (extremely thin compared to the Sun's 700,000 km radius).
The photosphere is the lowest layer of the solar atmosphere. In this layer, sunlight (visible light) is released as a result of energy bubbling up from the Sun's interior.
Thus, Sunspots are associated with regions of increasing magnetic field. It is visible on the Photosphere. According to one hypothesis, sunspots are caused by changes in the Sun's magnetic field. Over magnetically active regions, sunspots usually occur in pairs.

Answer:
When the entire lake reaches 40 F, the surface water cools further, dropping below 40 F. Because this water is now less dense than the surrounding water, it will stay on the top and continue to cool. Once the surface water falls to 32 F, it freezes. The freezing then spreads downward into the lake and the ice thickens
