Answer:
A physical blend of two or more substances!
Explanation:
Mixture is a chemical blend of two or more substances. Thus, the correct answer is option A.
What is a mixture?A mixture is a material composed of two or more different chemical substances that are not chemically bonded. A mixture is the physical combination of two or more substances that retain their identities and are mixed in the form of solutions, suspensions, and colloids.
Mixtures are created by mechanically blending or mixing chemical substances such as elements and compounds without the use of chemical bonding or other chemical changes, so that each ingredient substance retains its own chemical properties and makeup.
Despite the fact that its constituents do not undergo any chemical changes, the physical properties of a mixture, such as its melting point, may differ from those of the components.
Therefore, a chemical blend of two or more substances is called a mixture.

a. Slow population growth
c. Negative population growth
b. Rapid population growth
d. No change in population
A population pyramid that is in the shape of an "upside down triangle" shows that country is probably experiencing Negative population growth. The correct option is (c).
What do you mean by the population pyramid?
The population pyramid shows how the population is divided by gender and age at any given time. It consists of two histograms with the numbers displayed horizontally and the ages displayed vertically, one for each gender (by convention, males are on the left and women are on the right).
The age of a certain population can be represented as a pyramid. The distribution of a population's ages overall provides information on a species' potential for reproduction and chances of survival in ecology. Population density is the number of people per square meter of land.
Therefore, a population pyramid that is in the shape of an "upside down triangle" shows that country is probably experiencing Negative population growth.

A rocks and soil are pulled downhill by gravity
B sediment and sand are carried away by gusts of wind
Crocks are slowly broken down into sediment or soil
Drocks are carved out along shorelines by waves and streams
Answer:
C. rocks are slowly broken down into sediment or soil
Explanation:
Weathering is the breakdown of rocks, soils, and minerals as well as wood and artificial materials through contact with the Earth's atmosphere, water, and biological organisms.
The rocks are slowly broken down into sediment or soil, is defined as the weathering. Thus, option C is correct.
What is Weathering?Weathering is the degradation of rocks, soils, and minerals, as well as wood and man-made materials, caused by contact with water, atmospheric gases, and biological organisms.
It does not require the removal of rock. Weathering can be classified into three types: physical, chemical, and biological. Weathering is a significant procedure because it breaks down rocks and minerals, which aids in the formation of soil.
Soil is required for plant growth, which provides food and oxygen to animals and humans. Weathering is also responsible for the formation of landforms such as mountains, canyons, canyons, and plateaus.
Therefore, option C is correct, that the Weathering is the process by which rocks are gradually broken down into sediment or soil.

What physical feature allowed settlers in the Fertile Crescent to grow crops? sea tides flooding rivers natural canals eroding mountains
Hey there! I'm happy to help!
The Fertile Crescent is basically where human civilization started. It stretches from Mesopotamia and across the Mediterranean coast to Egypt. Early civilizations depended on agriculture. To make agriculture, you need a river because it is a good water source to help grow your crops.
If you look at the map I have provided below, you will see that there are tons of rivers. This would make it very easy for settlers to grow crops. This means that sea tides and eroding mountains aren't the answer. I don't think the rivers were flooding and natural canals is an oxymoron because canals are artificial waterways, but this all should give you and idea.
Have a wonderful day! :D
Rivers is the physical feature in Fertile Crescent.
Fertile Crescent is used to describe a region in the Middle East and was an ancient home to old civilizations.
This region spans across countries which includes Turkey, Iran, Iraq, Syria, Israel, Jordan, Egypt.The popular name was given because its contains fertile soil which were found near rivers in the region, thus encouraging development of agriculture.
