D. Answer the given questions.
1. How does the earth look from space?
2. How were lakes, rivers, land and mountains formed?
3. What is weathering?
4. How do rocks change into soil?
5. What are the various types of soil?
Answers
Explanation:
1.From space, Earth looks like a blue marble with white swirls. Some parts are brown, yellow, green and white. The blue part is water. ... Mapmakers use the line to divide Earth into two halves.
2.When rain falls on the land, it either seeps into the ground or becomes runoff, which flows downhill into rivers and lakes, on its journey towards the seas. ... As small creeks flow downhill they merge to form larger streams and rivers. Rivers eventually end up flowing into the oceans.
3.to change or make something change in appearance because of the effect of the sun, air or wind
4.Soil is formed through the process of rock weathering. Weathering is the breakdown of rocks into smaller particles when in contact with water (flowing through rocks), air or living organisms. ... This acidifies water in rocks leading to further chemical reaction with rock minerals.
5.Sandy soil. Sandy Soil is light, warm, dry and tend to be acidic and low in nutrients. ...
Clay Soil. Clay Soil is a heavy soil type that benefits from high nutrients. ...
Silt Soil. Silt Soil is a light and moisture retentive soil type with a high fertility rating. ...

Answer:
1)From space, Earth looks like a blue marble with white swirls. Some parts are brown, yellow, green and white.
2)When rain falls on the land, it either seeps into the ground or becomes runoff, which flows downhill into rivers and lakes, on its journey towards the seas.in this manner lakes and rivers are formed.mountains are formed The world's tallest mountain ranges form when pieces of Earth's crust—called plates—smash against each other in a process called plate tectonics, and buckle up like the hood of a car in a head-on collision.
3)Weathering is a term which describes the general process by which rocks are broken down at the Earth's surface into such things as sediments, clays, soils and substances that are dissolved in water.
4)rocks are changed into soil using weathering process.
5) various types of soil are:
clayey,sandy,loamy,red soil,black soil etc...
