Identify two possible reasons for the origin of settlements (cities)
Answer:
Physical factors that influence the location of a settlement include; 1. Water supply – settlements need water, they often locate on wet point sites for this. Settlements built away from rivers and water supplies to avoid flooding are located at dry point sites.

This is one of the three main types of rocks, one in which fossils are frequently found. These are layers of rock within which are characteristics that are different from layers surrounding it. This is a solid substance that is composed of minerals. This is the type of rock formed by the cooling of molten magma. This is the type of rock formed when they are subjected to higher temperatures and pressures which changes its mineral makeup This is a solid, inorganic substance with a crystalline structure that is formed through geological processes. This is a solid in which the basic unit is packed in an ordered, repeating pattern. This is is an underground layer of water-bearing permeable rock from which groundwater can be easily extracted using a well. This system identifies the scratch resistance of various minerals through the ability of a harder material to scratch a softer material. This is a characteristic of minerals. It describes the mineral's resistance to fractures or scratches. This is the color a mineral leaves behind after being dragged across an unweathered surface. This is a description of the way light interacts with the surface of a crystal, rock, or mineral. This is when minerals break on specific planes. This is the separation of a material into two, or more, pieces under the action of stress.

How do ocean currents work
Answer:
These currents are on the ocean's surface and in its depths, flowing both locally and globally. Winds, water density, and tides all drive ocean currents. Coastal and sea floor features influence their location, direction, and speed. Earth's rotation results in the Coriolis effect which also influences ocean currents.

Stigma The top of the female part of the flower which collects pollen grains
Ovary Produces the female sex cells (contained in the ovules)
Nectary Produce a sugary solution called nectar, which attracts insects"

what are two features formed by wave deposition
Answer:
Explanation:
The landforms or features that are formed by wave deposition include the following:
1. Beach: This is a coastal landform is formed when the waves move and spread the sediments along a coastline.
2. Sandbar: This is a long, narrow ridge of sand that is formed in a river or a sea. 3. Spit: It is an extended beach that looks like a finger or a hook that projects its way out into the sea.
4. Barrier islands: This is a lumpy area of sand that is formed when waves move the sediments in areas that are parallel to the main coast. This coastal landform protects the coastlines and creates wetlands.
Answer:
Some of the features formed by wave-deposited sand are. These features include barrier islands and spits. A spit is a sand connected to land and extending into the water. A spit may hook to form a tombolo.
Explanation:
Beaches are the most common features formed by wave deposition. One type of beach is the bayhead beach. This type of beach is formed when waves deposit material between two headlands. The picture below shows a bayhead beach in Brazil.

Explain the societal and cultural factors that may contribute to the high childhood and maternal mortality rates in sub- Saharan Africa.
They are the only mammals capable of self-powered flight, but they’re by no means rare. Bats account for about one in five of all mammals living on the planet and there are around 1,300 bat species worldwide. They are, however, threatened by loss of natural habitat and hunting, and many species of bat are considered endangered or threatened.
Though they’re the only mammals to have developed the ability to fly, they’re extremely good at it. The Mexican free-tailed bat can achieve speeds up to 99 miles per hour in the air and fly as high as 10,000 feet, as high as a bald eagle.
They’re the only flying mammals and are extremely diverse
How do rural water concerns differ between dry areas and areas with heavy
rainfall?
A. Dams for flood control are the biggest concern in dry areas, while
hydroelectric dams are a bigger concern in rainy areas.

boating are bigger concerns in rainy areas.
C. Draining marshes is the biggest concern in dry areas, while
irrigation is a bigger concern in rainy areas.
D. Conserving water is the biggest concern in dry areas, while runoff
is a bigger concern in rainy areas.
Answer: D
Explanation:
In dry areas, there is little to no water, so water conservation is of the utmost importance. In rainy areas, however, excess water can turn into flooding, which is why runoff is a much greater concern.

The amount of energy that Earth receives from the Sun per unit area is I. To find I, we can use this formula:
1 = 3.8 x 1020
In the formula, the variable r represents the distance from the Sun. Based on this formula, what effect will a highly
eccentric orbit have on the amount of energy received by the Sun? Answer in terms of perihelion and aphelion.
Answer:
During the aphelion, the distance from the Sun (r) is larger, leading to a lower amount of energy received from the Sun (I). During the perihelion, the distance from the Sun is smaller, leading to a higher amount of energy received. The higher the eccentricity, the higher the energy difference between perihelion and aphelion.

why should we study about environment
Answer:
Our environment is very important to us because it is where we live and share resources with other species. ... Environmental science enlightens us on how to conserve our environment in the face of increasing human population growth and anthropogenic activities that degrade natural resources and ecosystems.The ecosystem (all the communities of living organisms found in a specific place, their habitats and their interactions) in which we live provides natural services for humans and all other species that are essential to our health, quality of life and survival.
